Embodiment Construction

[0012] A polyvinyl chloride cable material with good light and thermal stability, made of the following raw materials (kg): polyvinyl chloride 86, polyvinylpyridine 44, resorcinol monobenzoate 18, white boron Calcium stone 21, chloroether resin 25, picrite 29, triglycidyl isocyanate 11, aromatic hydrocarbon modified terpene resin 29, white wax 10, serpentine tailings 20, pine smoke 8, epoxy acetylated castor oil Methyl ester 19, Di-n-octyl tin maleate 6, Butyl stearate 9, Titanium dioxide 18, Apatite 17.

[0013] A preparation method for polyvinyl chloride cable material with good light and thermal stability, comprising the following steps:

[0014] (1) Mix white boronite, picrite, serpentine tailings and apatite evenly, pulverize, sieve, then heat and melt to form a molten liquid, stir well, put it into clean water for water quenching, and dry , pulverized, sieved, 14000r / min high-speed ball milling for 2h, sieved, and then using nitrogen with a flow rate of 29L / min as the c...

Abstract

The invention discloses a polyvinyl chloride cable material with good light and heat stability and a preparation method thereof. The polyvinyl chloride cable material is prepared from 79-92 parts by weight of polyvinyl chloride, 36-48 parts by weight of polyvinylpyridine, 15-20 parts by weight of resorcinol monobenzoate, 18-24 parts by weight of pandermite, 20-30 parts by weight of a copolymer of vinyl chloride and vinyl isobutyl ether, 22-34 parts by weight of picrite, 8-13 parts by weight of triglycidyl isocyanurate, 6-7 parts by weight of a di-n-octyltin moleate polymer, 8-10 parts by weight of butyl stearate, 14-22 parts by weight of titanium dioxide and 13-21 parts by weight of apatite. Through polyvinyl chloride cable material formula improvement such as use of polyvinylpyridine, the copolymer of vinyl chloride and vinyl isobutyl ether, aromatic hydrocarbon-modified terpene resin, pine soot, epoxidized methyl acetoricinoleate and titanium dioxide, the prepared cable material has good light stability, good heat stability and good weatherability, greatly reduces polyvinyl chloride cable material light and heat aging rates and prolongs a service life of the polyvinyl chloride cable material.

Description

technical field [0001] The invention relates to a polyvinyl chloride cable material with good light and heat stability and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] Polyvinyl chloride (PVC) is a polymeric material (or resin) composed of the molecular formula CH 2 = CHCl monomer vinyl chloride (VCM) stacked multiple times. PVC is widely used in the wire and cable industry because of its good physical, chemical, electrical, and flame-retardant properties, as well as its low price. With the rapid development of the cable industry, there are higher and higher requirements for the performance of PVC cables. However, the light stability and thermal stability of existing PVC cable materials are more and more unable to meet the requirements of the market. Contents of the invention [0003] The object of the present invention is to provide a polyvinyl chloride cable material with good light and heat stability and a p...
