Embodiment 1

[0029] After cleaning, drying and crushing the waste agricultural film, weigh 75 kg of PVC waste which is extruded and filtered at 150°C by an extruder to obtain softened PVC waste, and add DOP plasticizer 5 1 kg, mixed back to obtain the film return material, add 25 kg of heavy calcium, 5 kg of PVC resin, 16 kg of DOP plasticizer, 4 kg of barium zinc stabilizer, 2.3 kg of ADC blowing agent, 1 kg of pigment in the film return material, After fully mixing to get the mixture, put the mixture into the internal mixer and knead at 150°C for 200 seconds, then feed it to the two-roll mill and knead at 150°C for 180 seconds, and then extrude the kneaded material extruded and filtered, the extrusion temperature is 150°C, the working speed of the extruder is 300 rpm, and then the extruded material is sent to a four-roll calender to be pressed into a film, and the temperature of the upper roll of the calender is 145°C. The temperature of the front roll was 145°C, the temperature of the m...

Abstract

The invention relates to a method for processing plastic floor material by utilizing PVC waste material, including: (1) PVC waste material is cleaned, dried and smashed and is subject to extrusion filtering at 130-150 DEG C by virtue of an extrusion machine, so that impurities are removed, and plasticizer is added, so as to form membrane feed back; (2) PVC resin, plasticizer, stabilizer, foaming agent and filler are added into the membrane feed back, mixing is carried out to obtain mixture, the mixture is subject to banburying at 140-160 DEG C for 150-220s, then is subject to milling at 140-160 DEG C for 3min and then is subject to extrusion filtering at 140-160 DEG C by virtue of the extrusion machine, and the working speed of the extrusion machine is 300r / min, film is made by virtue of a calendaring machine, and film pressing temperature is 130-160 DEG C; (3) the film is compounded onto a surface course coated with wear layer at 170-190 DEG C, heating foaming plasticizing and drying are carried out at 200-220 DEG C by virtue of a baking oven, and then cooling, trimming and crimping are carried out, thus forming the product. The invention utilizes PVC waste material to produce film, the produced film substitutes the blade coating foaming layer in plastic floor production process, production cost is reduced, recycling of waste PVC material is realized, and plentiful natural resources are saved.

Description

technical field [0001] The invention relates to a method for processing plastic floor materials by using PVC waste. Background technique [0002] PVC plastic floor is currently the most novel high-tech flooring material in the world's building materials industry. It is produced by coating process on sheet-like continuous substrate, and produced by calendering, extrusion or extrusion process. It has the functions of cleanness, tidiness, elasticity, sound absorption, beauty and elegance. With the improvement of people's living standards and environmental protection awareness, light-weight, recyclable, and colorful plastic flooring is gradually widely used in sports venues, hospitals, schools, offices and other fields. [0003] The manufacture of plastic flooring mostly adopts the scraping method of release paper, and the specific production process is as follows: [0004] 1. Ingredients: Mix PVC paste resin, DOP plasticizer, stabilizer, viscosity reducer, foaming agent, heav...
