AI Technical Summary

Benefits of technology

This patented technology allows manufacturers to create customized foam that looks like real wood when installed into various types of furniture without having any holes left open at all. It also includes methods for reclaiming used items such as scrap from production processes while producing quality foamed planks. Overall this innovation helps companies make better use of resources effectively.

Problems solved by technology

This patented technical problem addressed by this patents relates to finding better ways for making flexible films with good properties such as flexibility without losing strength when bent repeatedly over many times during use. Additionally, there needs to find new methods to reuse these film components effectively while ensuring stability under severe conditions like cold temperatures.

Abstract

The invention relates to a ethylene-propylene copolymer foamed material and a production technique thereof. The foamed material comprises the following components in parts by weight: 100 parts of copolymer, 1-5 parts of 1,3,5-triallyl-isocyanurate, 1-5 parts of silicon dioxide, 1-5 parts of petroleum resin, 1-5 parts of zinc white, 0.2-3 parts of stearic acid, 0.3-4 parts of hydrogen peroxide, 0.2-6 parts of polyurethane foaming agent, 1-100 parts of powdered filler, 1-20 parts of other functional modifiers and 0.1-16 parts of pigment. The production technique comprises the following steps: after proportionally preparing the materials, mixing and granulating or tabletting with a mixing roller, banburying kneader or screw extrusion mixing granulator; and foaming and forming the material with an hydraulic sulfurizing forming machine, injection sulfurizing forming machine or the like at 140-190 DEG C for curing time of 120-2000 seconds. The material has the advantages of high antiskid property, low surface hardness influence from air temperature, high softness and elasticity, and wide application range, and can be recycled.
