A processing method of composite foam and its hot-melt composite equipment

Abstract

The invention provides a processing method of composite foamed plastic and hot melting compound equipment thereof. The first step is the preparation of a half-finished product: 1, preparation before hot melting compounding: sequentially stacking foamed plastic, hot melt glue and a carrier in sequence, so as to form an object to be hot melted; 2, hot melting compounding: heating the object to be hot melted so as to perform hot melting and compression, and forming a hot-melt compound; 3, cooling and rolling: after cooling the hot-melt compound by decreased-temperature treatment, rolling to form the half-finished product; the second step is the preparation of an adhesive transfer: coating one surface of release paper with an adhesive, so as to form the adhesive transfer; the third step is transfer and press fit: press fitting the surface, coated with the adhesive, on the adhesive transfer, on a carrier surface of the half-finished product, so as to form hot-melt glue composite foamed plastic; in the abovementioned steps, the first step and the second step are both steps before the transfer and press fit of the third step, no successive sequence is applied, a sequence can be adjusted, and the composite foamed plastic is used for reducing the VOC (violate organic compound) discharge capacity of composite foamed plastic used in the industries of automobiles and household appliances and solving the problem of layering between the composite foamed plastic and an adhesive tape.

Description

technical field [0001] The invention relates to a composite foam composite method, composite equipment and a winding mechanism thereof; in particular, it relates to a composite foam processing method and hot-melt composite equipment. Background technique [0002] In the current automobile and home appliance industries, foam is usually used to achieve sound insulation, heat insulation, sealing, and shock absorption. The way to use it is to stick the foam to the preset bonding area of ​​the car or home appliance. [0003] At present, there are two ways to deal with foam to bond it to cars or home appliances: [0004] Method 1. Use oily non-low VOC pressure-sensitive adhesive to coat both sides of tissue paper or non-woven fabric, and then use release paper to isolate one side of the tissue paper or non-woven fabric to make oily non-low VOC pressure-sensitive adhesive tape. Finally, the oil-based non-low VOC pressure-sensitive tape is bonded to the foam material by rolling to...
