Abstract

PURPOSE:To improve the sliding property of a floor pad by a process wherein the heat curing synthetic resin containing aliphatic mono-carboxylate or light metal of aliphatic mono-carboxylic acid is impregnated into bulky non-fabric of base material to coat it. CONSTITUTION:A floor pad with dry finishing coat is made by the process that seize-coating material which is in the ratio of 'aliphatic mono-carboxylate of zinc sterate, magnesium sterate and something or light metal with aliphatic mono-carboxylic acid' 5-50(wt.) to 'heat curing synthetic resin' 100(wt.), is impregnated into bulky non-fabric of base material to coat it which is formed by temporarily fixing between web fibers made of synthetic fiber, by using of emulsion of synthetic resin. A stearic acid layer is thus made around resin, since the sterate and the light metal with stearic acid are softened and melted by friction heat. It is, therefore, difficult that floor wax sticks on floor pad, and the floor pad increases the resistance to wax release agents and hardly degrades or breaks.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary finishing floor pad used for cleaning and waxing floors of buildings, etc.

[Conventional technology and its problems]

Conventionally, this type of floor pad has been made of polyester,
Nonwoven fabrics made from synthetic fibers such as nylon are impregnated with synthetic resins such as phenol, epoxy, and urethane containing inorganic fillers such as calcium carbonate and silica, and lubricants. However, in recent years, the performance of rotary cleaning tools for floor pads has improved, and with the advent of ultra-high-speed poly lashers that can process at very high speed and in a short time), the performance of floor pads has become inferior to that high speed, and frictional resistance has increased. Various problems have occurred, such as scratches on the floor wax and deformation of the floor pad. In order to cope with such high-speed performance, the fibers used in the raw fabric are made thicker to enhance the heat dissipation effect of frictional heat. Round products are now on the market as improved products, but the fibers are thicker and the fibers and resin are less slippery. In addition to the sexual problem, there is also the drawback that the problem of scratches (surface roughness) on the floor wax has not been resolved.

(Means for solving problems) In view of the current situation, the present invention is an ultra-high-speed polygon.

To provide a floor pad for dry finishing which has sufficient durability for shearing, has excellent scratch roughness (glossiness) on the floor surface, and allows stable work over a long period of time. That is, the present invention applies an aliphatic monocarboxylate salt or aliphatic monocarboxylic acid light metal such as zinc stearate or magnesium stearate to a thermosetting synthetic resin such as phenol, epoxy, or urethane used for the size coat. By containing 5 to 50 parts per 100 parts and impregnating and coating a bulky nonwoven fabric as a base material, it is possible to obtain a floor pad for dry finishing that greatly improves the slipperiness of the synthetic resin. This solves the problem.

For dry finishing floor pads, use a wax remover with a wet floor pad, polish and clean the floor surface while peeling off the wax, and then use a dry waxing and dispensing pad to remove the wax.
-It is used after four layers of wax are applied, and the baking of the resin wax imparts its effect. Therefore, the performance required for finishing floor pads is to make the voids between the fibers coarser, improve heat dissipation,
Of course, physical properties such as interfiber strength 9 and rebound elasticity are the most important, but the slipperiness of the floor wax surface, the fibers of the floor pad, and the resin are the most important.

Therefore, it has been found that it is most logical to add an aliphatic monocarboxylic acid salt or a light metal aliphatic monocarboxylic acid to a thermosetting synthetic resin using as a secondary binder.

In addition, the addition amount of aliphatic monocarboxylate salts such as zinc stearate, magnesium stearate, and metals is 5 to 50 parts per 100 parts of thermosetting resin. is not achieved, and if the amount exceeds 50 parts by weight, the added stearic acid will drop off, which is not preferable.

[For production]

The present invention has the above configuration, so that during finishing work,
The stearic acid contained in the resin softens due to frictional heat and surrounds the resin particles, so as it is used, the surface smoothness improves and a wax layer with an ideal dry finish is formed.

In this way, once a wax layer of stearic acid is formed around the synthetic resin particles, stable surface smoothness can be obtained as described above, and a highly glossy finish can be achieved without scratching the floor wax layer.

In addition, as described above, in the floor pad of the present invention, a stearic acid layer is formed around the resin by softening and melting the stearate and the light metal stearate due to frictional heat, so that floor wax is difficult to adhere to, and the stearate is hard to adhere to. The acid layer also improves resistance to wax strippers and causes little deterioration damage to the floor pad.

The present invention will be described in detail below based on examples.

In addition, there is little change in shape and the product does not lose its shape. In addition, there is less adhesion of floor wax, and once the floor wax has adhered, it can be removed without deterioration due to the fiber and resin remover due to the softening wax layer of stearic acid that contains fiber resin, so it can be removed after cleaning. This invention has excellent effects such as no change in shape and stable polishing and cleaning work at all times.
