PVC material foaming chemical industry mixing auxiliary agent

Abstract

The invention relates to the field of PVC production aids, in particular to a PVC material foaming chemical industry mixing aid, and aims to solve the problems that the existing chemical aid is non-uniform in foaming, more in production procedures of an adding process, long in time consumption and poor in quality of a PVC product. According to the technical scheme, the PVC material foaming chemical industry mixing aid is prepared from the following raw materials in parts by weight: 250 to 350 g of a foaming agent, 450 to 550 g of a stabilizer, 450 to 550 g of a regulator, 100 to 200 g of an expanding agent, 200 to 300 g of a brightener, 20 to 40 g of a lubricant and 10 to 30 g of a plasticizer. According to the invention, the PVC material foaming chemical industry mixing aid can be rapidly added in one step when the PVC material is produced and used, has the advantages of time saving, labor saving and cost saving, and can compensate the air shrinkage during foaming of the PVC material, improve the anti-permeability, water resistance and crack resistance of the prepared PVC product, improve the flowability and demoulding property of the plastic during processing and forming, and improve the production and processing efficiency of the PVC material; and the prepared PVC product has a uniform foam structure, the processability of the PVC material and the appearance of the PVC product are improved, and the product is smooth and glossy in surface, good in density, good in temperature resistance, good in elasticity, easy to manage, low in defective rate, good in glossiness, bright in color, uniform in color, light and stable in quality.

Description

technical field [0001] The invention relates to the field of PVC production auxiliary agents, in particular to PVC material foaming chemical mixing auxiliary agents. Background technique [0002] PVC material is the world's largest general-purpose plastic, widely used in building materials, industrial products, daily necessities, footwear, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, foaming materials, sealing materials and fibers, etc. On the one hand, in the chemical production of PVC material foaming, it is necessary to add mixing additives for preparation. [0003] Existing chemical additives need to be purchased and added one by one in the production and use of PVC materials, resulting in cumbersome processing procedures, which do not have the characteristics of saving time, labor and cost; they cannot compensate for the shrinkage of PVC materials during foaming, which affects The anti-seepage, waterproof and crack resistanc...

AI Technical Summary

Problems solved by technology

[0005] The existing chemical additives proposed in view of the above background technology need to be added one by one by purchasing a single variety when the PVC material is produced and used, resulting in cumbersome processing procedures, which do not have the characteristics of saving time, labor and cost; they cannot compensate for the foaming of the PVC material. The drying shrinkage during drying will affect the impermeability, waterproof and crack resistance of PVC products; the fluidity and demoulding properties of plastics during processing and molding will be poor, which will reduce the performance of PVC products, resulting in time-consuming PVC demoulding and affecting PVC materials. The production and processing efficiency; the foaming cannot prevent the cell from breaking, resulting in uneven foaming, reducing the cell quality of the PVC foamed product, the processing performance of the PVC material and the appearance quality of the PVC product are not good, affecting the appearance of the product surface Insufficient smoothness and glossiness, the present invention provides PVC material foaming chemical mixing auxiliary agent, which solves the above-mentioned problems
