Problems solved by technology

The traditional PVC diaphragm is made by mixing PVC resin with stabilizers, processing aids and reinforcing agents, and then plasticized, extruded, calendered, and peeled off. The strength of PVC diaphragms mainly depends on the ratio of reinforcing agents. The price of the reinforcing agent is relatively expensive, resulting in high production costs; and after adding a certain amount of reinforcing agent, the strength will no longer increase significantly

Abstract

The invention discloses a PVC (Polyvinyl Chloride) diaphragm and a manufacturing method thereof. The PVC diaphragm is manufactured by using the raw materials: 100 parts of PVC resin, 1.0-1.2 parts of 719 type oxidized polyethylene wax, 0.015-0.017 part of auxiliary stabilizer, 3.5-4.0 parts of MBS (Methacrylate-Butadiene-Styrene) resin, 0.9-1.1 parts of ACR (Acrylate), 0.45-0.55 part of internal lubricant, 0.1-0.2 part of external lubricant, 0.3-0.4 part of PX1000, 0.011-0.013 part of ultramarine and 0.004-0.005 part of disperse purple, wherein the auxiliary stabilizer is composed of monomethyltin and antimony mercaptide which are in the weight ratio of 1:4. The manufacturing method of the PVC diaphragm comprises the steps: firstly, adding all the raw materials into a kneading pot to knead, and discharging when the temperature is up to 80-90 DEG C; entering a cooling pot, and discharging when the temperature is up to 60-70 DEG C; next, squeezing out the raw materials at the temperature of 120-160 DEG C; then, calendering the raw materials at the temperature of 180-200 DEG C to form a sheet; after stripping, cooling and shaping, cropping and winding. The PVC diaphragm is good in stability, high in strength and low in manufacturing cost.

Description

technical field [0001] The invention relates to a PVC diaphragm, and also relates to a manufacturing method of the PVC diaphragm. Background technique [0002] PVC film has good weather resistance, good flatness, easy affinity with most plastic inks, and has very obvious economy, so it is widely used in signs, panels, guard cards, credit cards and screen printing in the screen printing industry. Various decorative products. The traditional PVC diaphragm is made by mixing PVC resin with stabilizers, processing aids and reinforcing agents, and then plasticized, extruded, calendered, and peeled off. The strength of PVC diaphragms mainly depends on the ratio of reinforcing agents. The price of the reinforcing agent is relatively expensive, resulting in high production costs; and when the reinforcing agent is added to a certain amount, the strength will no longer increase significantly. Contents of the invention [0003] The primary purpose of the present invention is to over...
