Polystyrene foam recovery regeneration buffer packing gasket and production method thereof

Abstract

The invention relates to a polystyrene foam plastics recycling regeneration cushion packaging pad and a fabrication method thereof, belongs to the field of the packing material, and mainly solves the problems of the polystyrene foam plastics, the waste paper fiber recycling and the energy conservation and the environmental protection. The recycled polystyrene foam plastics are crushed into particles with 2-10 mm, the waste paper fiber is produced into paper pulp, and water is filtered out naturally, after the paper pulp is evenly mixed with the water-based adhesive diluted with the water according to a certain mass ratio; a die is infused, which is dewatered through pressurization and molded; then drying is performed; and finally the finished product can be obtained through surface finishing. The polystyrene foam plastics recycling regeneration cushion packaging pad and the fabrication method thereof have the advantages that both the polystyrene foam plastics and the waste paper fiber are recycled material, easy to obtain and have low cost; the fabricated cushion packaging pad has light weight and good cushioning property, can fully meet the requirements of product packing and also can be reused; since the adhesive adopts the environmental friendly water-based adhesive, not only the white pollution is greatly reduced, the energy resources and the resources are saved, but also the rejected material can be changed into resources, the development of the cyclic economy can be promoted, and meanwhile, the process is simple and convenient, the implementing is easy, and no pollution is generated.

Description

technical field [0001] The invention belongs to the field of packaging materials, and relates to recycled and regenerated polystyrene foam plastic cushioning packaging liners and a manufacturing method thereof. Background technique [0002] The cushioning packaging liners used in large quantities in transport packaging are mainly polystyrene foam (EPS) and polyethylene foam (EPE). Although they have the advantages of excellent cushioning performance, low cost and mature production technology, their packaging waste It cannot be degraded naturally, which will cause serious "white pollution", and is plagued by green barriers and energy resource crises; in addition, paper-based cushioning packaging materials, such as corrugated cardboard and honeycomb cardboard, are widely used in the market. Its advantage is that the waste is easy to weather naturally and easy to recycle. The disadvantage is that the surface is hard, it is difficult to make a liner similar to the surface shape ...

AI Technical Summary

Problems solved by technology

[0002] The cushioning packing liners widely used in transport packaging are mainly polystyrene foam (EPS) and polyethylene foam (EPE), although they have excellent cushioning properties , low cost and mature production technology, but its packaging waste cannot be degraded naturally, which will cause serious "white pollution", and is troubled by green barriers and energy resource crises; in addition, paper is more widely used in the market Quality cushioning packaging cushioning materials, such as corrugated cardboard and honeycomb cardboard, have the advantage that the waste is easy to weather naturally and are easy to recycle. The disadvantage is that the surface is hard and it is difficult to make a cushion similar to the surface shape of the packaged object. , and has poor moisture resistance and low recovery; while pulp molding products are rich in raw materials and develop rapidly, because of their limited cushioning performance and strength, they are only suitable for cushioning packaging for some small commodities
