AI Technical Summary

Benefits of technology

This patented technology provides for improved durable coatings made from elastomeric materials that can withstand extreme conditions such as heat or cold without losing their effectiveness over time. These coatings are used on various products like tires, boats, pipes, roofers, etc., providing better protection against corrosion caused due to environmental factors like rainwater damage.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the performance of waterproof layers applied on building constructions while reducing their vulnerabilities from outside influences like winds and rainwater. Current methods involve adding polymers with strong adhesion properties (such as acrylic acid) to increase its bond between different components within the material itself. This results in stronger films without being easily broken down under pressure. Additionally, existing solutions require expensive equipment at elevated temperatures making them less effective than desired because they may lead to issues related to clogging pores caused by small molecules formed through evaporation processes.

Abstract

The invention relates to a spraying quenching rubber asphalt waterproof coating. The spraying quenching rubber asphalt waterproof coating is prepared according to the following steps: vulcanizing rubber emulsion, thereby acquiring the vulcanized rubber emulsion; preparing the vulcanized rubber emulsion, unvulcanized rubber emulsion, anion emulsified asphalt and additive into liquid rubber asphalt mastic emulsion; preparing the liquid rubber asphalt mastic emulsion and the coagulant at ratio into the spraying quenching rubber asphalt waterproof coating. According to the spraying quenching rubber asphalt waterproof coating provided by the invention, a method for vulcanizing the rubber emulsion is adopted for preparing the vulcanized rubber emulsion, so that the preparation temperature for the vulcanized rubber emulsion and the spraying quenching rubber asphalt waterproof coating is greatly reduced. The spraying quenching rubber asphalt waterproof coating which is prepared from the coagulant and the liquid rubber asphalt mastic emulsion made from the vulcanized rubber emulsion, unvulcanized rubber emulsion, anion emulsified asphalt and additive at ratio has higher tensile strength and water resistance, higher chemical resistance, high temperature resistance and low temperature resistance.
