Problems solved by technology

Ordinary polyvinyl chloride composite materials are highly sensitive to changes in the use environment and cannot be used for protection
[0005] Aiming at the shortcomings of traditional polyvinyl chloride composite materials that cannot be well adapted to the use environment, publication number 105924729A discloses a cable material with improved flame retardancy and mechanical properties
However, improving the flame retardancy and mechanical properties does not make the material use complex and changeable environment

Embodiment 1

[0034] Ingredients: The raw materials are weighed according to the composition and parts by weight of the above polyvinyl chloride composite material, including 100 parts of polyvinyl chloride, 5 parts of nitrile rubber, 13 parts of TOTM plasticizer, 47 parts of KW27 polyester, and 4 parts of soybean oil , 0.2 parts of calcium stearate, 0.8 parts of polyethylene wax, 15 parts of octabromoether, 3 parts of antimony trioxide, 4 parts of CZ-200 rubber vulcanization accelerator, 15 parts of kaolin, 4 parts of calcium carbonate, 2 parts of carbon black , 0.5 parts of titanium dioxide, 1.5 parts of methyl methacrylate, and 4 parts of tetrafluoroethylene copolymer.

[0035] Machine refining: first put polyvinyl chloride, TOTM plasticizer, KW27 polyester, soybean oil, kaolin, calcium carbonate, and methyl methacrylate into the internal mixer, set the processing temperature to 150°C, and process for 15 minutes to obtain the mixture 1 for use, then put the remaining materials into the i...

Embodiment 2-3

[0038] The only difference with Example 1 is that the parts of polyvinyl chloride in the batching of Examples 2-3 are respectively 80 parts and 120 parts.

Embodiment 4

[0040] The only difference with Example 1 is that the parts of TOTM plasticizer in the batching of Example 4 are 10 parts and 40 parts of KW27 polyester.

Abstract

The invention discloses a polyvinyl chloride composite material and a preparation process thereof and belongs to the technical field of cable materials. The polyvinyl chloride composite material comprises the following components in parts by weight: 80-120 parts of polyvinyl chloride, 3-8 parts of nitrile rubber, 50-70 parts of a plasticizer, 2-8 parts of a lubricant, 10-30 parts of a flame retardant, 3-5 parts of a rubber vulcanization promoter, 10-30 parts of auxiliary aids and 3-5 parts of a tetrafluoroethylene copolymer. A conventional polyvinyl chloride composite material is relatively low in dosage of a single plasticizer and insufficient in material flexibility, and as the content ratio of the plasticizer to the polyvinyl chloride in the polyvinyl chloride composite material is approximate to 1:2, the flexibility and the cutting property of the product are greatly improved. Meanwhile, materials are mechanically mixed in different batches and further commixed, mechanical mixing and extrusion conditions are adjusted according to properties of different substances sufficiently, and thus the comprehensive properties of the product are effectively improved.

Description

technical field [0001] The invention relates to a polyvinyl chloride composite material and a preparation process thereof, belonging to the technical field of cable materials. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic with large output, low price and excellent performance. It is widely used in medical, chemical, electrical, decorative and other fields. [0003] Polyvinyl chloride has the characteristics of good comprehensive mechanical properties, flame retardancy, and chemical corrosion resistance. Different plasticizers can be added to meet different requirements. However, polyvinyl chloride products have the disadvantages of poor impact resistance and heat resistance, which restricts the application range of polyvinyl chloride products to a certain extent. [0004] Due to different ingredients, PVC composite materials can be selected and produced in a wide variety, and the quality varies greatly. They are usually made of auxiliar...
