Problems solved by technology

[0003] At the same time, PVC resin is the basic material for door and window profiles, and its usage accounts for about 80%. Although PVC has good physical properties, it also has many shortcomings, such as poor thermal stability, high melt resistance, and high brittleness. It cannot meet the requirements of processing and use when used, so how to modify PVC has become a very concerned issue.

Embodiment 1

[0015] Embodiment 1 provides a modified plastic for processing PVC door and window profiles, which includes polyvinyl chloride with a percentage greater than 85.6% and the balance of monomeric lead salt, antioxidant, composite stable lubricant, and ACR-201.

[0016] Among them, the composite stable lubricant is composed of heat stabilizer, lubricant and antioxidant, and ACR-201 can promote the gelation speed of the melt, improve the strength of the melt, improve the uniformity and fluidity of the plasticization of the melt, Give the product good surface gloss.

[0017] A kind of processing modified plastics for producing PVC door and window profiles, the method comprises the following steps:

[0018] (1) The polyvinyl chloride of 90.3% by mass percentage is uniformly mixed with the solvent of the remainder, and the solvent includes 1.2% monomer lead salt, 0.5% antioxidant, 3.5% composite stable lubricant, 4.5% ACR-201 and water;

[0019] (2) Process the mixed solution into p...

Abstract

The invention relates to an organic polymer composite material and specifically relates to a PVC door and window profile processing modified plastic. The modified plastic comprises more than 85.6% of polyvinyl chloride and the balance of monomer lead salt, anti-oxidant, composite stable lubricant and processing improvement-type ACR. The PVC door and window profile processing modified plastic of the invention can improve thermal stability, uniformity and fluidity of melt plasticization and hot welding performance for secondary processing of the PVC.

Description

technical field [0001] The invention relates to an organic macromolecule composite material, and more specifically relates to a process-modified plastic for PVC door and window profiled materials. Background technique [0002] PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains a softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use is limited. Rigid PVC does not contain softeners, so it has good flexibility, easy to shape, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC. The essence of PVC is a vacuum blister film, which is used for the surface packaging of various panels, so it is also called d...
