[0028] Examples 1-4: A silane crosslinked flame-retardant polyvinyl chloride cable material and its preparation method

[0029] Silane crosslinked flame-retardant polyvinyl chloride cable material, its raw material formula (unit: parts by weight) is shown in Table 1:

[0030] Table 1 Silane cross-linked flame-retardant PVC cable material

[0031]

[0032] The name of each component raw material used in the embodiment of table 2:

[0033]

[0034]

[0035] The production process is carried out in one step according to the following steps: preparation of raw and auxiliary materials-measurement and weighing according to the formula ratio-high-speed kneading-extrusion mixing and plasticization by twin-screw extruder unit-single-screw granulation-cooling and sieving-guarantee. The kneading process uses a high-speed kneader to raise the temperature of the raw and auxiliary materials to 130-140°C under high-speed friction, and obtain sufficient mixing and pre-plasticization; ...

Abstract

A silane crosslinked flame-retardant polyvinyl chloride cable material and its preparation. The raw materials include the following components in parts by weight: 100 parts of PVC resin; 30-40 parts of plasticizer a; 20-30 parts of plasticizer b; flame retardant a 5-10 parts; flame retardant b 5-20 parts, filler a 10-40 parts, filler b 20-30 parts; heat stabilizer 2-10 parts; lubricant 0.5-2 parts; antioxidant 0.1-0.3 parts ; 0.1-2 parts of silane cross-linking agent, the silane cross-linking agent is a mixture of silane a, silane b and silane c; 5-10 parts of toughening agent a; 5-10 parts of toughening agent b; auxiliary agent 0.3 -0.8 parts. The silane cross-linked flame-retardant polyvinyl chloride cable material of the present invention is mainly used in places with high-temperature resistance and high-strength requirements for household use, and has higher gel rate, better mechanical strength and color stability, and has high strength, heat resistance and Creep resistance without lead salt as catalyst.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride cable materials, in particular to a silane crosslinked flame-retardant polyvinyl chloride cable material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a halogen-containing polymer material, pure PVC granular material, high mechanical strength, very good weather resistance, water resistance, chemical resistance and good electrical insulation materials, although it is resistant to light and heat It is sensitive, but the light and heat stability of PVC can be improved by adding stabilizers. With the improvement of the production capacity of PVC resin, plasticizer and industrial additives and the development and application of environmental protection products, PVC has made a qualitative leap in wire and cable. With the improvement of people's awareness of safety and environmental protection, more and more products need to comply with ROHs and REACH regu...
