Embodiment Construction

[0027] Carry out proportioning each composition by the weight shown in table 1.

[0028]

[0029] Each component weight of table 1 embodiment 1-4

[0030] Wherein, in embodiment 1-4, the average degree of polymerization of polyvinyl chloride resin is 800-1500; Chlorine content is 65%-70% in the chlorinated polyvinyl chloride resin; , 60nm, 80nm; the stabilizer is an organotin stabilizer.

[0031] The specific method of calcium carbonate surface treatment is: put calcium carbonate into the mixer, heat to 60°C and keep it warm for an appropriate time, then add titanate coupling agent into the mixer and mix evenly, and discharge the material after 10-25 minutes for use , Pay attention to keep the calcium carbonate dry to prevent moisture absorption.

[0032] The preparation process is as follows: S1. Weigh each component according to the weight in Table 1, mix them evenly in a pre-mixer, heat to 70-90°C, and keep warm for 15 minutes;

[0033] S2. Put the mixture obtain...

Abstract

The invention discloses high-strength and high-stability modified PVC (polyvinyl chloride) which comprises the following components in parts by weight: 100 parts of PVC resin, 20-55 parts of CPVC (chlorinated polyvinyl chloride) resin, 15-20 parts of phenolic antioxidant, 1-12 parts of titanium dioxide, 15-35 parts of plasticizer, 2-8 parts of stabilizer, 0-3 parts of colorant, and 2-10 parts of filling. The high-strength and high-stability modified PVC has the benefits that: the modified PVC has good mechanical property, high strength, good balance of stiffness and toughness, heat resistance, light resistance, corrosion resistance, and high stability; the service life of a product is ensured; in addition, the preparation method is good in repeatability; the process is controllable; the manufacturing cost is low; and the industrial large-scale application is facilitated.

Description

technical field [0001] The invention relates to a modified PVC, which has high strength and high stability, is especially suitable for anti-scratch strips in the field of automobile manufacturing, and belongs to the field of polymer materials. Background technique [0002] PVC (polyvinyl chloride) material has the advantages of good mechanical properties, flame retardancy, good electrical insulation, low manufacturing cost and easy processing. It is widely used in the production of plastic soft products, pipes, product packaging and many other fields. With the development of the automobile industry, studies have found that polyvinyl chloride is expected to be widely used in automobile manufacturing as anti-scratch strips, but the performance of general PVC is difficult to meet the requirements of high strength and high stability of anti-scratch strips, so there is an urgent need Modification of PVC to make it have better mechanical properties, high strength, good balance of ...
