PVC resin, PVC paste resin and fusion process method of PVC resin and PVC paste resin after dispensing solidification

Abstract

The invention provides PVC resin, PVC paste resin and a fusion process method of the PVC resin and the PVC paste resin after adhesive dispensing solidification. The fusion process method comprises thefollowing steps that (1) a PVC paste resin raw material is injected into a dispensing mold in a dispensing mode, and then is dried to obtain PVC paste resin; (2) the PVC paste resin is cooled; and (3) a PVC resin raw material is subjected to injection molding based on the obtained PVC paste resin.

Description

technical field [0001] The invention relates to the plastic manufacturing industry, and more specifically, relates to a fusion process of PVC resin, PVC paste resin, and glue dispensing and solidification. Background technique [0002] PVC resin (polyvinyl chloride) is one of the important organic synthetic materials. Chemical structural formula: (CH2-CHCL)n, its products have good physical and chemical properties, and are widely used in industry, construction, agriculture, daily life, packaging, electric power, public utilities and other fields. Polyvinyl chloride (PVC) paste resin, as the name implies, is a resin that is mainly used in the form of a paste. People often call this paste plasticized paste, which is a unique liquid form of PVC plastic in its unprocessed state. . Paste resins are often prepared by emulsion and microsuspension methods. Due to the fine particle size, the PVC paste resin has a texture like talcum powder and has no fluidity. The polyvinyl chlor...

AI Technical Summary

Problems solved by technology

However, the manufacturing cost and processing difficulty through the dispensing process are high, and the tear resistance of plastic products manufactured through the dispensing process is poor

In addition, the thickness of the plastic products produced by the dispensing process is relatively low, and thicker plastic products cannot be produced, and the power consumption of the dispensing process is relatively large, which does not support mass production

[0005] In addition, this traditional processing technology cannot process different types of materials into an integrated structure, especially for products with complex shapes and structures, which may require welding or bonding in multiple places

In this way, the processing process not only needs to consume more materials, but also the labor cost of the processing process is high, and the yield is relatively low.

Adhesive or welding is currently the most common way to solve the connection of two plastic materials of different materials, but the plastic products made by gluing or welding are easy to be torn during use, and it is easier to break when exposed to water in the middle. open, which is the main reason for the short service life of the product

[0006] In addition, the existing plastic fusion process is difficult to process plastics of different materials together, and the yield of the traditional fusion processing process is low

Limited by the processing source and processing technology, the plastics formed by fusion processing usually have poor performance, or the fusion parts of the produced products are easy to crack, etc.
