Method for producing foaming cushion

Abstract

The invention discloses a preparing method of foaming pad, which comprises the following steps: allocating fitful PVC powder, DOP plastic agent, light-weight calcium carbonate, kaolin, foamer and pigment, casting in the composite device to form liquid slurry, transmitting in the middle material barrel, stewing at normal temperature for 8h, prefoaming, coating the transmitting belt to form slurry layer, stewing the slurry layer at 80-90 deg.c for 3-10min, heating at 185-200 deg.c for 20-30 min, foaming entire foam pad, cooling, punching, moulding the outline shape and distinctive line of surface, cutting, obtaining foaming pad product.

Description

technical field [0001] The present invention is related to a cushion body, and specifically refers to a manufacturing method capable of forming continuous interconnected air cells inside a molded foam cushion body, so that it has better fatigue resistance properties. Background technique [0002] Press, foam pads are widely used, especially in people's livelihood and sporting goods. Generally, foam pads are generally made of appropriate amount of PVC powder, DOP plasticizer, light calcium carbonate, kaolin, foaming agent and The color materials are mixed with each other, and then coated on the conveyor belt or release paper by roller pressing, and foamed and formed by heating at high temperature, and finally, the required foam cushion product is obtained by hot pressing and cutting by the mold. [0003] But, the manufacturing method of known foam cushion body, though can make various foam cushion body finished products, all do not communicate with each other between each air...

Problems solved by technology

[0003] But, the manufacturing method of known foam cushion body, though can make various foam cushion body finished products, all do not communicate with each other between each air bubble that forms in this foam cushion body interior, and are countless closed air bubbles. Therefore, when the foam pad body is under pressure, since the individual air cells under pressure cannot communicate with other bubbles, a rebound force will be generated immediately. Therefore, although the foam pad body has cushioning elasticity, the Its rebound or slow force is strong. For some products for human body, such as insoles or sports pads, etc., it will cause discomfort to the pressure parts such as feet. If it is used for a long time, it may even cause There is a phenomenon of muscle soreness, so how to improve the manufacturing method of the known foam pads to obtain the really desired foam pad structure is indeed necessary
