At present, wet curtain paper with the synthesis technique of resol generally is: phenol and formaldehyde under the condition of basic catalyst, pH be 8～10,70～90 ℃ of isothermal reactions to the certain viscosity scope, promptly obtain desired product.This kind technology is widely used at wet curtain paper, but because the price height of phenol, about 14000 yuan/ton, causes production cost height, rate of profit low.
Summary of the invention
The present invention is directed to deficiency, propose a kind of wet curtain paper resol, adopt low cost raw material to substitute expensive phenol, reduced production cost, and kept product performance.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of wet curtain paper with the preparation method of resol is: the phenol and the aldehyde that add mol ratio 1: 2.0～4.0 in reactor, and the xylogen and the alkali that accounts for phenol weight 2%～8% that account for phenol weight 10%～60%, carry out polycondensation, resin viscosity to generation is 20～50cp/25 ℃, be cooled to rapidly below 40 ℃, get resol.
Preferably, phenol and the xylogen that accounts for phenol weight 10%～60% are dropped into reactor, refluxed 1.5～2.5 hours, add aldehyde and alkali again.
Preferably, to account for the weight ratio of phenol be 30%～50% to described xylogen.
Preferably, described alkali is sodium hydroxide or potassium hydroxide.
Preferably, the consumption of described alkali is 3%～5% of a phenol weight.
Preferably, described xylogen is alkali lignin, sulfonated lignin, the biomass enzymolysis xylogen that wood pulp or straw pulp produce in the paper industry.
Preferably, described polycondensation is carried out under 70 ℃.
Compared with prior art, the present invention adopts xylogen instead of part phenol, comes novolak resin; Because the reserves of existing xylogen are only second to Mierocrystalline cellulose, and all regenerate every year with 50,000,000,000 tons speed.Pulp and paper industry will be isolated about 1.4 hundred million tons of Mierocrystalline celluloses every year from plant, obtain the xylogen byproduct about 5,000 ten thousand tons simultaneously, but up to now, surpass 95% xylogen still directly enter rivers with " black liquor " or concentrate after burn, seldom be utilized effectively.Preparation method of the present invention has reduced the production cost of resol.Free aldehyde of this patent synthetic resol product and free phenol content are few, and production environment and environment for use are had greatly improved.
Xylogen is a kind of complicated phenol polymer that is formed by four kinds of alcohol monomers (to tonquinol, lubanol, 5-hydroxyl lubanol, sinapyl alcohol).At present xylogen mixes by following three kinds of monomers: the syringyl lignin that is formed by Syringa oblata Lindl. base propane structure monomer polymerization; The guaiacyl xylogen that forms by guaiacyl propane structure monomer polymerization; The p-hydroxybenzene xylogen that forms by p-hydroxybenzene propane structure monomer polymerization.
The chemism of this patent synthetic technology is: in the presence of basic catalyst (pH=8～10), phenol and xylogen are miscible in proportion, add formaldehyde then, and the constant temperature polycondensation forms under the certain temperature.
Resol synthetic ultimate principle is:
(1) in the presence of basic catalyst, phenol and formaldehyde at first react the generation hydroxymethyl phenol, because the influence of methylol makes an ortho position and a contraposition activation on the phenol nuclear.These active hydroxymethyl phenols that when being subjected to the attack of formaldehyde, generate ortho position or contraposition.
(2) because formaldehyde is excessive, all right and formaldehyde generation addition reaction of hydroxymethyl phenol generates binary methylolphenol and ternary methylolphenol.
(3) product of addition reaction is the mixture of hydroxymethyl phenol and polynary hydroxymethyl phenol, about these hydroxymethyl phenols and phenol or react each other and generate the resol of linear structure.
Discover, contain various active functional group simultaneously in the molecular structure of lignin monomer, wherein hydroxyl exists in xylogen at most, has the physics and the chemical property that how much have directly influenced xylogen of phenolic hydroxyl group with alcoholic extract hydroxyl group and two kinds of forms of phenolic hydroxyl group.Therefore the phenolic hydroxyl group that contains in the xylogen and the structural similitude of resol can replace a part of phenol to react with xylogen.
The present invention also provides a kind of preparation method of wet curtain paper, may further comprise the steps:
1., the phenol and the aldehyde that in reactor, add mol ratio 1: 2.0～4.0, and the xylogen and the alkali that accounts for phenol weight 2%～8% that account for phenol weight 10%～60%, carry out polycondensation, extremely the resin viscosity that generates is 20～50cp/25 ℃, be cooled to rapidly below 40 ℃, get resol;
