Abstract

The invention relates to a preparation method of a chemical modified bitumen reclaimed rubber and asphalt waterproof coating. According to the proportions of 200g 40 mesh tread compound power, 40g No. 60 petroleum asphalt, 10g No. 200 petroleum asphalt, 4g 420 activator and 4g rosin, materials are put into a reactor provided with a high-speed stirring device and reacted for 2 hours when the reaction temperature is about 220 DEG C; then 14g modifier maleic anhydride is added at the same temperature and the mixture is continued to be stirred at 200 DEG C and reacted for 15min; after mixing, the modified reaction reclaimed rubber is added with 850g toluene and the mixture is dispersed by a high speed stirrer. The invention has the advantages of improving adhesive strength and tensile strength.

Description

The method of chemical-modification reclaimed rubber asphalt waterproofing paint

Technical field

The present invention relates to a kind of method of chemical-modification reclaimed rubber asphalt waterproofing paint.

Background technology

The waterproof paint and the basal plane bonding force that with the regenerated rubber asphalt are main raw material at present are low, and intensity is on the low side.

Summary of the invention

The objective of the invention is to overcome above-mentioned defective, a kind of method of chemical-modification reclaimed rubber asphalt waterproofing paint is provided.

Technical scheme of the present invention is: a kind of method of chemical-modification reclaimed rubber asphalt waterproofing paint, it is characterized in that: directly mix the maleic anhydride modified agent 200 ℃ of reactions 15-30 minute before finishing by the shoddy desulphurization reaction, the properties-correcting agent add-on is not more than 50% of desulfurization regeneration glue weight, add a certain amount of pitch and solvent again, promptly make waterproof paint; By mix the maleic anhydride modified agent in mixing desulfurization regeneration glue immiscible organic solvent system, 110-120 ℃ of reaction 2 hours, the properties-correcting agent add-on was not more than 50% of desulfurization regeneration glue weight.

The present invention has the following advantages: bonding strength and tensile strength all have raising.

Embodiment

Embodiment 1: a kind of method of chemical-modification reclaimed rubber asphalt waterproofing paint, by 40 order tyre surface rubber powder 200g, No. 60 petroleum pitch 40g, No. 200 petroleum pitch 10g, 420 activator 4g, rosin 4g ratio feeds intake, throw to the reactor that high-speed stirring apparatus is housed, about 220 ℃ reactions earlier of temperature of reaction 2 hours, under same temperature, drop into properties-correcting agent MALEIC ANHYDRIDE 14g then, continued stirring reaction 15 minutes down at 200 ℃, above-mentioned modified-reaction reclaimed rubber uses 850g toluene miscible after mixing, and high speed dispersor disperses.

Embodiment 2: a kind of method of chemical-modification reclaimed rubber asphalt waterproofing paint, through mixing desulfurization regeneration glue 200g, include 30g60 petroleum pitch and 600g toluene is miscible, admixture 10g MALEIC ANHYDRIDE, 110-115 ℃ of following back flow reaction 2 hours, reaction mixture was filmed after with the high speed dispersor hydrotropy.
