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

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

[0030]

[0031] The name of each component raw material used in the embodiment of table 2:

[0032]

[0033]

[0034] The production process is carried out 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—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; the temperature setting of the twin-screw...

Abstract

The invention relates to a silane-crosslinking flame-retardant polyvinyl chloride cable material and a preparation method thereof. The cable material contains the following components: 100 parts of PVC resin, 30-40 parts of a plasticizer a, 20-30 parts of a plasticizer b, 5-10 parts of a flame-retardant agent a, 5-20 parts of a flame-retardant agent b, 10-40 parts of a filler a, 20-30 parts of a filler b, 2-10 parts of a heat stabilizer, 0.5-2 parts of a lubricant, 0.1-0.3 part of an antioxidant, 0.1-2 parts of a silane cross-linking agent, 5-10 parts of a flexibilizer a, 5-10 parts of a flexibilizer b and 0.3-0.8 part of an aid, wherein the silane cross-linking agent is a mixture of silane a, silane b and silane c. The silane-crosslinking flame-retardant polyvinyl chloride cable materialis mainly applied to the domestic sites with requirements on high temperature resistance and high strength, has relatively high gel rate, relatively good mechanical strength and color stability and high strength, heat resistance and creep resistance, and lead salt does not need to be taken as a 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 thermal 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 r...
