Abstract

The present invention relates to the technical field of foam, in particular to a process for preparing foam by reusing foam waste, comprising the following steps: step A: cutting the foam waste into three kinds of granular waste with different particle sizes; step B: cutting The particle waste obtained by cutting in step A is evenly dispersed, then adding foaming agent, antibacterial agent, coloring agent, filler, and mixing to obtain a mixture; step C: spray glue into the mixture obtained in step B, stir evenly, and then add Carry out molding and steam foaming treatment in the molding equipment to obtain foam material; step D: cutting the foam material obtained in step C to obtain foam. The process of reusing foam waste to prepare foam according to the invention is simple in operation, easy to control, high in production efficiency, can recycle discarded foam leftovers, improves resource utilization, and reduces foam production cost.

Description

Technical field [0001] The present invention relates to the field of foam, and more particularly to a process of foam waste re-utilizing the preparation of bubble foam. Background technique [0002] With the rapid development of society, the use of foam materials greatly increases. Due to the advantages of high flexibility, large elasticity, good water absorption, more applied to cosmetic cotton, washing utensils, sofa cushions, car cushions, children's anti-collision Cushion and other products. [0003] However, during the preparation of the above-mentioned foam material, the foam material needs to be cropped, while the remaining foam waste after cutting, it is a waste, resulting in waste of resources, and for production enterprises, waste recycling It has an important influence in the generation cost. Inventive content [0004] In order to overcome the disadvantages and deficiencies in the prior art, it is an object of the present invention to provide a process of foaming wast...
