Abstract
A bitumen blend comprises bitumen and a polymer binder, which is low density polyethylene most preferably having a melt flow index of from 0.3 to 0.4 and which most preferably also, is present from about 15 to 18% by weight. The softening point of the blend is preferably about 107 to 120 DEG C. The composition may be used as a waterproofing compound for roofing or for use in carpet tile backings.
Description
BITUMENlPOLYETHYLENE BLEND FOR ROOFING AND THE LIKE
This invention relates to a modified bitumen blend for use particularly but not exclusively in roofing.
Roofing may be waterproofed by the application of a coated bituminous membrane or laminate. Conventionally, such felt has comprised of a layer of rag base - fibreglass, paper or hessian coated with oxidised bitumen and bonded by hot oxidised bitumen.
Bitumen may be oxidised to improve its mechanical properties, but other developments, as described in
U,S. Patent No. 4368228, include modifying the bitumen with polymers such as styrene-butadiene-styrene block copolymer, atactic polypropylene, and polyisobutylene.
The examples in the patent show a polypropylene blend further modified by amorphous ethylenejpropylene copolymer.
A desirable bitumen blend should have a good processing viscosity at the coating temperature, a high softening point to resist slump in summer and good low temperature flexibility to prevent cracking in winter it is very desirable that the rheological changes described be achieved with a minimum addition of modifying compound.
It is an object of the present invention to provide a useable bitumen for roofing and the like, by an addition of at least 12% by weight of a modifying compound.
According to the present invention there is provided a bitumen blend for roofing damp courses and carpet tile backings, comprising bitumen and at least 12% by weight of a low density polyethylene (hereinafter polyethylene) having a melt flow index of from 0.2 to 005.
Preferably the melt flow index is 0.3 to 0.4 and more preferably there is from 15 to 18% by weight polyethylene.
In the production of, for example, the roofing felt ar.d the base materials used are standard and form no part of the invention.
As shown in Graph 1, for a bitumen/polyethlene blend, the softening point increases sharply past a critical concentration of modifying polymer, possibly as a polymer network is formed (see upper plateau in Graph 1). The inventor has however, found that a surprisingly low concentration of polyethylene is actually required to form a continuous phase of polyethylene, with a good processing viscosity. As can be seen from the aforementioned U.S. Patent, the trend is towards highly amorphous systems, with the minimum concentration of modifying polymer.It is therefore highly surprising.on a hindsight comparison with the apparently more amorphous atactic polypropylene (at least 20% by weight)- that the inventor has found a cost effective bitumen blend which requires only at least 12% by weight of a polyethylene, the characteristics of which are hereinbefore defined.
The bitumen/polyethylene blend can be used in (for example) the production of roofing materials dampcourse and in carpet tile backings The blend is prepared by mixing straight run bitumen, preferably 200pen, (BS4691) with low density polyethylene of melt flow index 0.2 to 0.5 preferably 0.3 to 0.4 where the polyethylene may vary from about 12% to 20%, at an elevated temperature, until a smooth dispersion mixture, with a softening point in the region of 107degC-120degC, is obtained.This mixture may be filled with a mineral filler such as calcium carbonate, fly ash or slate dust, up to a loading of 40%
Once the mixture has been prepared, it may be applied using conventional techniques to rag fibre, paper, fibreglass, asbestos, hessian and polyester bases, or any combination of the aforementioned in a laminate, to produce a water-proofing membrane which may be finished with sand, talc, slate granules or aluminium flakes on the top surface and, in the case of traditional roll and ppur felts, sand on the bottom or with a cast polypropylene/ polyethylene film where the product is to be applied with a gas torch.
The invention will now be described by way of example: Exaluple 1
The composition of a typical mixture which may be advantageously used in the manner described above would be:200 pen bitumen - 86%) 60% low density polyethylene(BS3412) - 14%) limestone filler 40,0 This mixture would also be suitable for carpet tile backing in place of conventional filled oxidised bitumen.
The advantage of polyethylene midified bitumen over conventional oxidised bitumen are:1. Improved resistance against slump at high temperatures.
2. Improved low temperatux flexibility (down to -lOdegC).
3. Improved ductility.
Example 2
The following blend was prepared again as before:15% polyethylene ! 70% 85t 200pen )
Filler 30%
Four tests were carried out on this blend to determine its suitability: the softening point, penetration at 250C, the low temperature flex and the viscosity at typical processing temperatures. The softening point must be high enough to avoid substantial slump in the summer yet have sufficient flexibility to avoid brittleness in the winter.
The blend should further have reasonable hardness and a reasonable processing viscosity.
The following properties noted, and a graph (No. 2) prepared of viscosity against temperature for example 2: a. softening point - llldegC b. penetration @ 25degC - 23dmm c. low temperature flex - lOdegC
D. viscosities at 155 degC - 11900 cps " " 160degC - 9300 cps " " 165degC - 7900 cps It It l70degC - 6700 cps Results were tabulated (table 1) showing the temperature.jviscosity characteristics of bitumen blend, at specific percentages of polyethylene.
Bitumen/P.E. blends

As shown in Table 1 and graph 1, there is a sharp rise in the viscosity and softening point of the bitumen blend surprisingly between about 6% and J2% of polyethylene addition.Thereafter the softening point increases only slightly with further addition of polyethylene.Thus below about 6% ptlyethylene there is a dispersion of polyethylene in a continuous bitumen phase; from about 6% to about 12%, there is phase inversion; and about 12% and above the polyethylene in the continuous phase. Above about 20% the blend becomes too viscous for piratical use. The inventor has therefore found that an apparently less amorphous system in comparative terms actually requires a good deal less modifying polymer to bring about phase inversion, than say bitumen/polypropylene, and have thereby found a useable and cost effective bitumen blend.
Furthermore, as can be seen from the rest of the results of example 2 and the graphs, the softening point, low temperature flex and penetration are superior to conventional oxidised bitumen (95/25; 111/15) presently being used by the roofing industry. The viscosity is good for processing of the blend, intact at the normal processing temperature of about 1600C, the resulting viscosity of 9300cps was ideal-and the blend can be surprisingly produced at a cost effective minimum addition of about 12% of the defined polyethylene.
It will be appreciated that further polymers such as selectively shown from the aforementioned U.S. Patent can be added to further modify the bitumen/polyethylene blend.
