Composite embossed non-woven fabric

Abstract

The invention discloses a composite embossed non-woven fabric which is prepared by subjecting EPE and a low-pressure membrane to direct hot pressing on an embossing calendar under the conditions of a hot pressing temperature of 110 to 120 DEG C and a rotating speed of a pressure roller of 800 to 1200 RPM and then compounding the pressed low-pressure membrane and EPE with a non-woven fabric through tape casting of a coating layer formed by a mixture of an adhesive and a low density polyethylene resin particle, wherein an upper layer is the low-pressure membrane, a middle layer is the EPE, a lower layer is the non-woven fabric, the usage amount of the low density polyethylene resin particle accounts for 20 to 40% of the weight of a coating material, and the thickness of the low-pressure membrane is 8 to 25 mu m. Since the low density polyethylene resin particle is cheaper than the adhesive, the composite embossed non-woven fabric provided by the invention has reduced production cost while the compounding quality of the non-woven fabric, the EPE and the low-pressure membrane is ensured, and improves bonding strength of the low-pressure membrane and the EPE through controlling the hot pressing temperature and the rotating speed of the pressure roller, allowing bonding between the low-pressure membrane and the EPE to be firmer.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to non-woven fabric composite materials, in particular to a composite embossed non-woven fabric. Background technique [0002] EPE pearl cotton is a new type of environmentally friendly packaging material, which is composed of numerous independent bubbles produced by physical foaming of low-density polyethylene. It overcomes the shortcomings of ordinary styrofoam such as fragility, deformation, and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and strong impact resistance. Good chemical resistance is an ideal substitute for traditional packaging materials, widely used in electronic appliances, instruments, computers, audio, medical equipment, industrial control chassis, hardware lighting, handicrafts, glass, ceramics,...

AI Technical Summary

Problems solved by technology

[0005] A single non-woven fabric limits its application field and needs to be used in combination with other materials. The combination of low-pressure film, pearl cotton and non-woven fabrics has been widely used. Composite embossed non-woven fabrics need to be used in the process of casting and compounding Coating materials such as adhesives, due to the high price of adhesives, the cost of composite embossed non-woven fabrics is relatively high
