Problems solved by technology

However, the existing EPDM waterproof coating has defects in the formula, which cannot overcome the self-cleaning problem caused by the precipitation of the EPDM waterproof coating, and the filler in the EPDM coating is difficult to dissolve in the solvent. It is well integrated with rubber and resin, and it is easy to separate and differentiate during use, which will affect the service life of EPDM rubber coatings

Abstract

The invention discloses a multi-prevention EPDM rubber coating and a preparation technology thereof, and raw materials of the coating comprises the following components in proportion by weight: 60-80 of EPDM rubber, 8-12 of teflon resin, 15-25 of SBR, 50-70 of terpene resin, 50-70 of SBS, 4-6 of anti-aging dispersing additives, 15-25 of nanometer calcium carbonate, 4-8 of basic magnesium carbonate, 6-10 of nanometer titanium white, 15-25 of nearsphere silicon micro-powder and 450-550 of solvent. The multi-prevention EPDM rubber coating has the functions of waterproofness, anti-corrosion, inflaming retarding, dust prevention and self-cleaning, the formula constitution is reasonable and can realize homogenous stability of long-term storage, the formula constitution is simple, the raw material proportion is reasonable, thus the defect that padding is easy to separate from rubber component in the coating is eliminated. The preparation technology of the multi-prevention EPDM rubber coating is simple and is suitable for industrial production.

Description

technical field [0001] The invention belongs to waterproof paint and its preparation technology, in particular to a multi-proof EPDM paint with waterproof, anti-corrosion, flame-retardant, dust-proof and self-cleaning functions and its preparation process. Background technique [0002] EPDM waterproof coating is a waterproof engineering material with EPDM as the main raw material. EPDM is basically a saturated polymer compound with no polar substituents in the molecule, and the chain links are more flexible. , its excellent aging resistance is the best among general-purpose rubbers: it also has good ozone resistance, weather resistance and heat aging resistance. However, the existing EPDM waterproof coating has defects in the formula, which cannot overcome the self-cleaning problem caused by the precipitation of the EPDM waterproof coating, and the filler in the EPDM coating is difficult to dissolve in the solvent. It is well integrated with rubber and resin, and it is easy...
