Description
Technical Field
The invention relates to the technical field of PVC (polyvinyl chloride) profiles, in particular to a high-weather-resistance polyvinyl chloride profile for doors and windows and a preparation method thereof.
Background
PVC is a non-crystalline, polar high molecular polymer with high softening temperature and melting temperature, pure PVC generally needs to be plasticized at 160-210 ℃, and PVC shows hard and brittle properties due to polar bonds between macromolecules. Moreover, the PVC molecule contains chlorine groups, and when the temperature reaches 120 ℃, HCl removal reaction begins to occur in pure PVC, which can cause thermal degradation of PVC.
With the development of industrial technology, the processing of PVC materials as building materials is becoming more and more widespread, for example, PVC profiles applied as door and window materials have been developed vigorously over the last ten years, but most products in the prior art still have the certain quality problems, such as poor weather resistance of the products, discoloration of the product surface after aging, and reduction of residual impact strength and tensile strength after aging. Some discoloration is also related to the residual strength of the product after aging, which directly affects the service life of the product. Therefore, more and more efficient high-performance building materials are desired, for example, PVC profiles for doors and windows are required to have higher rigidity, weather resistance, high temperature resistance and the like.
In a patent document with publication number CN105153599A, a high weather-resistant PVC profile for doors and windows is disclosed, which comprises the following raw materials in parts by weight: PVC resin: 420 parts of (B); ACR processing aid: 13-14 parts; a stabilizer: 25 parts of (1); chlorinated polyethylene: 50-55 parts; CaCO 3: 32 parts of (1); superfine CaCO 3: 20 parts of (1); titanium dioxide: 36-38 parts; antioxidant: 2-2.5 parts; ultraviolet absorber: 1.4-2 parts; ultramarine: 2.5-3 parts of stabilizer which is one or more of calcium stearate, calcium ricinoleate, zinc stearate and zinc ricinoleate, and the invention also discloses a production process of the section. According to the invention, the PVC profile has higher rigidity, wind pressure resistance and low-temperature reinforcement by optimizing the profile raw materials and the preparation process; however, with the continuous development of the PVC profile field, the impact strength, weather resistance and high temperature resistance of the PVC profile need to be further improved.
