Problems solved by technology

[0004] The most important material in plastic-steel doors and windows is polyvinyl chloride, that is, PVC resin; polyvinyl chloride has good processing characteristics and outstanding mechanical properties, but the material's toughness, low temperature resistance, and high temperature resistance are poor. Embrittlement deformation occurs, and the toughness of the material is greatly reduced. In this state, after being impacted, PVC is very easy to crack and lose its supporting effect.
[0005] As far as PVC is concerned, in order to improve its toughness and low temperature resistance, some elastomer materials can be added to the material, but while elastomer materials improve the toughness and low temperature resistance of PVC, it will lead to significant stiffness and hardness. The mechanical strength of the material is affected; such a material is difficult to be used in the manufacture of support structures such as door and window profiles

Abstract

The invention relates to the technical field of polymer materials, in particular to a cold-resistant and crack-resistant PVC resin for door and window plastic steel profiles. The PVC resin includes PVC, ACR processing aid, filler, cold-resistant toughening agent, polyethylene wax, composite stabilizer, ultraviolet absorber and antioxidant. The cold-resistant toughening agent is a novel material prepared by compounding a plurality of elastomer materials and high-hardness fillers; the filler is a mixture of titanium dioxide and light calcium carbonate; the composite stabilizer contains calcium-zinc stabilizer and di-n-butyltin dilaurate; the ultraviolet absorber is ultraviolet absorber RMB, ultraviolet absorber UV-9 or ultraviolet absorber UVP-327; and the antioxidant is antioxidant 164, antioxidant 1076 or antioxidant TNP. The PVC resin material has good toughness and outstanding low temperature resistance, and is not easily embrittled under low temperature conditions. The cold-resistant and crack-resistant PVC resin is good in impact resistance and does not crack easily.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC resin for cold-resistant and crack-resistant door and window plastic-steel profiles. Background technique [0002] Doors and windows are divided into enclosure components or partition components according to their positions, which are important components in the building enclosure structure system. According to the different types of materials, the doors and windows on the market today can be roughly divided into the following categories: wooden doors and windows, steel doors and windows, plastic steel doors and windows, aluminum alloy doors and windows, glass steel doors and windows, stainless steel doors and windows, iron flower doors and windows. With the continuous improvement of people's living standards, the types of doors and windows and their derivative products are still increasing, and the grades are gradually rising, such as heat-insulated broken bridge...
