Problems solved by technology

The traditional method is only for the deodorization method of EPDM rubber. Generally, the use of odorless vulcanizing agent and deodorant will affect the performance of EPDM, and then affect the performance of EPDM foam.
And cannot remove formaldehyde, ammonia and TVOC
[0006] The application number is 201410480570.5 "A Formula of Environmentally Friendly and Odorless EPDM Rubber", the application number is 201410067778.4 "EPDM Environmentally Friendly Rubber Hose and Its Manufacturing Method", and the application number is 201610534069.1 "A High Temperature, Oil, and Low Odor EPDM Yuan ethylene propylene rubber composition" all mentioned the use of deodorant, although it can reduce the odor, but can not fundamentally remove harmful gases such as formaldehyde, ammonia and TVOC

Abstract

The invention discloses a compounded bio-enzyme solution for aldehyde removal and odor removal of EPDM foam, and a preparation method thereof. The formula of the compounded bio-enzyme solution comprises, by weight, 20-30% of bio-enzyme, 20-30% of plant extract, 0.1-0.5% of carboxymethyl chitosan, 0.01-0.1% of glutathione, 1-5% of a pH buffering agent, and the balance of deionized water. The compounded bio-enzyme solution can be applied to remove formaldehyde, ammonia, TVOCs, residual vulcanizing agents and other residual assistants from the EPDM foam, eliminate irritant smell of the EPDM foamand reduce the peculiar smell in automobiles. The compounded bio-enzyme solution has the advantages of convenience in use, high treatment efficiency, high pertinence and low cost, and is a green, pollution-free and environmentally-friendly product.

Description

technical field [0001] The invention relates to a compound biological enzyme solution of EPDM foam for removing aldehyde and deodorizing and a preparation method thereof, and belongs to the technical field of environmental biology. Background technique [0002] EPDM foam, also called EPDM foam material. Ethylene propylene diene rubber (EPDM) is a terpolymer of ethylene, propylene, and a non-conjugated diene. EPDM foam is made of EPDM foam material by using EPDM rubber as the main raw material, through banburying, mold foaming, trimming, slicing and other steps. [0003] EPDM foam has excellent weather resistance, ozone resistance, corrosion resistance, heat resistance, stability, good thermal insulation, heat insulation, cushioning, shock resistance, sound absorption, sound insulation, sealing, flame retardant and other characteristics. Based on the above characteristics, EPDM foam is widely used between auto parts for filling, dustproof, shockproof, sealing and waterproof...
