Abstract

The invention discloses a high-molecular weather-resistant waterproof adhesive. According to the invention, lactic acid/glycerol organic zirconium with an obvious temperature-sensitive cross-linking characteristic is used as a cross-linking agent, an ethylene-ethyl acrylate copolymer fiber base solution is used as a thickening agent, and cross-linking is carried out to form gel with good temperature resistance and shearing resistance; and through adoption of the fiber-processed copolymer base solution, surface activity of the copolymer can be improved, cross-linking effect is promoted, and viscoelasticity and thixotropy of the adhesive are enhanced.

Description

A kind of polymer weathering resistance water-resistant adhesives and preparation method thereof

Technical field

The present invention relates to a kind of tackiness agent, particularly relate to a kind of polymer weathering resistance water-resistant adhesives and preparation method thereof.

Background technology

Traditional vegetable jelly tackiness agent, at high temperature facile hydrolysis, poor to the protectiveness of base material, and the thickening capabilities of ethylene-ethyl acrylate copolymer is strong, heat resistance is good;

The most frequently used linking agent of usual acquisition polymer gel is organic boron or organic zirconium, and organic borate cross-linker heatproof is the highest can only reach 150 DEG C, and organic zirconium can be cross-linked in acid condition, and heatproof is high, can reach 200 DEG C, has broad application prospects.

Summary of the invention

Object of the present invention is just to provide a kind of polymer weathering resistance water-resistant adhesives and preparation method thereof.

The present invention is achieved by the following technical solutions:

A kind of polymer weathering resistance water-resistant adhesives, it is made up of the raw material of following weight parts:

Salpeter solution 0.3-0.4, the ethylene-ethyl acrylate copolymer 200-210 of emulsified bitumen 100-110, tricalcium silicate 3.2-5, tetrafluoroethylene 4-7, sisal fibers 10-15, sp-80 1-1.4,10-12mol/l, zirconium oxychloride 1.3-2, lactic acid 0.5-1, glycerol 0.6-1, anti-aging agent CMA 0.1-0.2, triglycol two 2-ethylhexoate 10-15, waste rubber powder 20-30, ricinolic acid 2-3.

A preparation method for polymer weathering resistance water-resistant adhesives, comprises the following steps:

(1) get the 30-40% of above-mentioned emulsified bitumen weight, mix with waste rubber powder, after stirring, add anti-aging agent CMA, insulated and stirred 20-30 minute at 80-90 DEG C;

(2) by sisal fibers and tricalcium silicate mixing abrasive dust, join in 30-50 times of water, under agitation condition, add remaining emulsified bitumen, sp-80,100-200 rev/min stir 30-40 minute;

(3) by each raw material mixing after above-mentioned process, add ethylene-ethyl acrylate copolymer, drip the salpeter solution of 10-12mol/l under agitation condition, be heated to boiling, adjustment PH is 6-6.5, is stirred to normal temperature, obtains copolymer fibre base fluid;

(4) joined by zirconium oxychloride in 2-3 times of water, stirring and dissolving, adds lactic acid, glycerol, and regulation system pH value, to 4-5, is uniformly mixed 4-5 hour, obtains organic zirconium crosslinker;

(5) by copolymer fibre base fluid, organic zirconium crosslinker mixing, at 70-85 DEG C, be uniformly mixed 30-40 divide, discharging cools, and obtains organic zirconium gel;

(6) mixed with each raw material of residue by above-mentioned machine zirconium gel, raised temperature is 170-180 DEG C, insulated and stirred 1-2 hour, adds each raw material of residue, continues to stir 30-40 minute, and through tank cooling, cut off shaping, dehydration, vacuum-drying, to obtain final product.

Advantage of the present invention is:

The present invention with lactic acid/glycerol organic zirconium for linking agent, it has obvious temperature sensitive crosslinking feature, with ethylene-ethyl acrylate copolymer fiber base fluid for viscosifying agent, pass through crosslinked action, the gel with good temperature and shearing sustainability can be formed, adopt the multipolymer base fluid of fiber treatment, multipolymer surfactivity can be improved, promote cross-linking effect, improve visco-elasticity and thixotropy;

Adhesives of the present invention is strong, and good weatherability, is particularly suitable in pavement construction for the bonding between asphalt pavement and Cement Concrete base interface layer; adhesive power is strong; improve the weight capacity on road surface, effectively protect road surface, the phenomenon such as not easily occur crack, rut, come off.
