Problems solved by technology

But when making PE, EVA or PEVA plastic cloth with this kind of traditional method, because of the characteristic of PE, EVA or PEVA material, cause the three-dimensional embossing on it to become blurred, and when rolling three-dimensional embossing, to The continuous strength of PE, EVA or PEVA plastic cloth will cause damage, resulting in the embossed plastic cloth made of discontinuous or uneven strength, which is easy to be torn at the embossed position

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings, but the implementation scope of the present invention is not limited.

[0015] The invention relates to a method for manufacturing environmentally friendly PE, EVA, and PEVA secondary embossed cloths. In the method, plastic granules (or powder) and colorants of polyolefin plasticized materials are injected into a feeding funnel, and After being stirred evenly by a stirrer in the hopper, it is introduced into an extruding sleeve equipped with a heating element outside, and the plasticized material is heated by the heating element in the extruding sleeve to gradually form a molten state, Driven by an extruding screw provided in the extruding sleeve, it flows to a T-shaped die provided at the other end of the extruding sleeve, and through this T-shaped die, a flat plastic cloth (or plastic film), and then the plastic cloth is cooled, and then the plastic cloth is introduc...

Abstract

The production process of twice grained cloth includes the following steps: mixing PE, EVA, PEVA or other polyolefin material and coloring material inside a stirrer; heating and extruding the mixture in a screw extruder with heating assembly to a T-shaped mold to form plastic cloth; cooling; rolling the plastic cloth with roller with surface stereo grains and inside heating assembly while heating the surface of the plastic cloth to form grains; and re-cooling to obtain environment friendly plastic cloth with surface stereo grains and of PE, EVA, PEVA or other polyolefin material.

Description

technical field [0001] The invention provides a method for manufacturing a secondary embossed cloth (including plastic cloth or plastic film), especially a method made of polyethylene (Polyethylene, referred to as PE), ethylene vinyl acetate copolymer (Ethylene Vinylacetate, referred to as EVA) or A manufacturing method in which three-dimensional reliefs are continuously produced on the surface of a plastic cloth or plastic film made of plasticized materials such as polyethylene vinyl acetate (PEVA for short). Background technique [0002] Generally speaking, most of the problems of environmental protection come from various plastic products. These plastic products are widely used in various industries such as electronics, information, communication, optoelectronics, medical equipment and daily necessities, resulting in a large amount of plastic waste. It can decompose in the natural environment or garbage dump, and can resolve toxic substances, causing serious pollution to ...
