Benefits of technology

The invention relates to an improved method for producing rubber products that are more durable than traditional methods used today. This can be achieved by copying or duplicating certain parts from existing materials instead of creating new ones altogether.

Problems solved by technology

Technological Problem: Current methods for improving the properties of waterproof paints by adding nano particles or other materials have limitations such as causing paint sedimentation during application resulting from insufficient dispersion between the filling agent (rubber) and the resin itself, leading to nonuniformity over time due to settling issues caused by gravity flow, poor mixing efficiency when mixed together, etc., making this method challenges at least until now.

Abstract

The invention provides an environment-friendly ethylene propylene diene monomer (EPDM) rubber waterproof coating and a production method thereof. The coating comprises the following dry materials by the total mass parts of the coating: 80-120 parts of EPDM rubbers, 25-35 parts of SBR, 50-70 parts of terpene resins, 50-70 parts of SBS, 3-7 parts of nanometer zinc oxide, 45-65 parts of nanometer calcium carbonate, 4-10 parts of nanometer titanium dioxide and 430-550 parts of 120# solvent oil. Three kinds of nanoparticles are added to the coating, and through scientific proportioning, the fillers can be uniformly dispersed in the solvents with the rubbers, thus solving the precipitation problem of the coating and greatly improving intermixing. The waterproof coating also has the functions of ozone decomposing, sterilizing and self-cleaning, and meanwhile, the performances of the material are all improved. As the 120# solvent oil is added, the coating has the characteristics of non-toxicity, dust prevention, fouling prevention and self-cleaning.
