Abstract
A kind of film water-proof glue belongs to waterproof construction coating, and it is the manufacture method of the liquid coating waterproofing coating of tar polyurethane two liquid response types.The present invention adopts trihydroxy-polyoxytrimethylene ether, dihydroxyl polyoxytrimethylene ether, tolylene diisocyanate, and dibutylester, coal tar, inferior benzene residual oil is a raw material, mixes together at a certain temperature; Production technique of the present invention is simple, and equipment is few, and cost is low, and bonding force is strong, and unit elongation is big, and springiness is cold-resistant, heat-resisting, ageing-resistant, and drug-resistant performance is good, airtight, characteristic such as watertightness is high and water resistance is splendid.
Description
The present invention relates to a kind of waterproof construction coating, film water-proof glue specifically, it is the liquid coating waterproofing coating of tar polyurethane two liquid response types, is applicable to roofing, hypogee, surface structures, seam, anticorrosion, bonding etc.
As everyone knows, usually roof waterpoof material has petroleum pitch and linkrusta, endures the pitch contaminate environment of smoldering during construction, operates not only dirty but also tiredly, and inflammable dangerous, is difficult for constructing in winter; Emulsificated asphalt water-proof painting material is because of the breakdown of emulsion of enduring cold, deterioration failure, and waterproof effect is poor; Poly-ammonia vinyl waterproofing unction need heat during use, easily catches fire, and valuable product; Shortcomings such as the polystyrene type modified water-proof coating exists poor high temperature stability, and set time is long.
The purpose of this invention is to provide a kind of film water-proof glue, be intended to overcome above-mentioned shortcoming, can substitute the liquid coating film waterproof material of bituminous tar polyurethane two liquid response types, have characteristics such as bonding force is strong, unit elongation big, cold-resistant, heat-resisting, ageing-resistant.
The object of the present invention is achieved like this:
A kind of film water-proof glue is formed by giving aggressiveness (first component) and solidifying agent (component B),
Giving aggressiveness (first component) is by weight percentage
Tolylene diisocyanate 14-20%,
Trihydroxy-polyoxytrimethylene ether 38-46%,
Dihydroxyl polyoxytrimethylene ether 16-24%,
Dibutylester 16-22%,
Temperature of reaction kettle is controlled at more than 75 ℃, drops into above-mentioned raw materials successively, stirring heating is warming up to 85 ℃, and constant temperature got final product to such an extent that give aggressiveness in 1 hour again;
Solidifying agent (component B) is by weight
Coal tar 62-78%,
Inferior benzene residual oil 20-30%,
3,3 '-dichloro-4,4,4 '-diaminodiphenylmethane 2-6%, earlier coal tar is dropped in the reactor, be warming up to 140 ℃ of dehydrations, be cooled to 100 ℃ then and add 3,3 '-dichloro-4,4,4 '-diaminodiphenylmethane, be cooled to 80 ℃ again and add time benzene residual oil, stirring to make solidifying agent; To give aggressiveness (first component) during construction and mix by 1: 2 weight ratio with solidifying agent (component B), stir the back film water-proof glue.
Concrete manufacture craft is:
Give the preparation of aggressiveness (first component), by producing 100 kilograms, the tolylene diisocyanate that in reactor, adds the 14-20 kilogram earlier continuously, 10～14 kilograms trihydroxy-polyoxytrimethylene ether, 8～12 kilograms dihydroxyl polyoxytrimethylene ether, 2～3 kilograms dibutylester, heated and stirred, be warming up to 75 ℃, add 14～16 kilograms trihydroxy-polyoxytrimethylene ether for the second time, 4～6 kilograms dihydroxyl polyoxytrimethylene ether, 2～4 kilograms dibutylester, stirring heating is warming up to 75 ℃, adds 14～16 kilograms trihydroxy-polyoxytrimethylene ether for the third time successively, 4～6 kilograms dihydroxyl polyoxytrimethylene ether, the dibutylester of 12-15 kilogram, heated and stirred is warming up to 85 ℃, and constant temperature discharging in 1 hour promptly makes 100 kilograms of flaxen first components.
The preparation of solidifying agent (component B), by producing 200 kilograms, take by weighing 140～150 kilograms of adding reactors of coal tar after the dehydration, be warming up to 140 ℃, constant temperature till do not have a bubble, then feed temperature is reduced to 100 ℃ add 6～10 kilograms 3,3 '-dichloro-4,4,4 '-diaminodiphenylmethane, to stir and be cooled to 80 ℃ of inferior benzene residual oils that add 40～60 kilograms again, the discharging that stirs promptly makes the component B of 200 kilograms of black.
During construction the first component is mixed by 1: 2 weight ratio with component B, can use after stirring.Advantage of the present invention is: manufacturing process is simple, and use equipment is few, easily operation.Cost of the present invention is low, and is cheap, reduced building cost, and construction is not subject to seasonal restrictions, and unit elongation is big after the film forming, springiness, cold-resistant, heat-resisting, ageing-resistant, drug-resistant performance is good, airtight, resistance to air loss is high, water resistance is splendid, the construction after fixing phase is short, strong adhesion, bonding force height.
Most preferred embodiment:
Give the preparation of aggressiveness (first component): the tolylene diisocyanate that takes by weighing 17.85 kilograms, 12 kilograms trihydroxy-polyoxytrimethylene ether, 9.10 the dihydroxyl polyoxytrimethylene ether of kilogram and 2.5 kilograms dibutylester add in the reactor successively, stirring is warming up to 75 ℃, the trihydroxy-polyoxytrimethylene ether that feeds intake for the second time and add 15 kilograms, 6 kilograms dihydroxyl polyoxytrimethylene ether and 3 kilograms dibutylester, stirring is warming up to 75 ℃, the trihydroxy-polyoxytrimethylene ether that feeds intake for the third time and add 15 kilograms, 6 kilograms dihydroxyl polyoxytrimethylene ether and 13.55 kilograms dibutylester, heat temperature raising to 85 ℃, constant temperature stirred 1 hour, discharging get final product 100 kilograms first component.
The preparation of solidifying agent (component B): take by weighing in 142 kilograms of adding reactors of coal tar of high temperature dehydration, be warming up to 142 ℃, till no bubble is overflowed, add when then temperature in the kettle being reduced to 100 ℃ 8 kilograms 3,3 '-dichloro-4,4,4 '-diaminodiphenylmethane, continue to be cooled to 80 ℃ of inferior benzene residual oils that add 50 kilograms, the discharging that stirs get final product 200 kilograms component B.
