Problems solved by technology

However, due to the poor thermal stability and heat resistance of PVC, the plasticizing effect is unstable, and it is easy to volatilize and migrate. When preparing hard products, the apparent viscosity of the melt is high, the processing fluidity is poor, the hard products are brittle, and the impact resistance is poor, which greatly limits its use

Abstract

The invention discloses a modified polyvinyl chloride composite material and a preparation method thereof. The modified polyvinyl chloride composite material is prepared from the following raw materials in parts by weight: 140-150 parts of polyvinyl chloride, 13-15 parts of butadiene-acrylonitrile rubber, 5-7 parts of zinc stearate, 6-8 parts of dibutyltin maleate, 1-2 parts of a current-based organic tin stabilizer, 6-9 parts of alkyl phosphate, 6-8 parts of polysiloxane, 7-10 parts of polyethylene wax, 6-8 parts of a silane coupling agent, 2-3 parts of alumina powder, 4-6 parts of tris-(2,4-di-tert-butyl-pheny)-phosphite, 7-9 parts of graphite fluoride, 8-10 parts of cubic boron nitride micro-powder, 9-11 parts of an emulsion interfacial agent, 5-7 parts of vinyl trimethoxy silane, 6-8 parts of ammonium alcohol ether sulphate, 7-8 parts of an ultraviolet light absorber, 5-6 parts of an antioxidant TNP, and 10-12 parts of additives. According to the invention, the zinc stearate added, and simultaneously used with calcium ricinoleate, so that the synergetic effect is good, and the weather resistance of products can be enhanced; the nano silica is added, and simultaneously used with graphite fluoride, so that the tensile strength can be synergetically increased, and the impact strength can be improved; and the added ultraviolet light absorber and the current-based organic tin stabilizer achieve a synergetic effect, so that the disadvantage of poor light fastness is improved, and the service life is increased.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a modified polyvinyl chloride composite material and a preparation method thereof. Background technique [0002] Polyvinyl chloride is an important thermoplastic, which has the outstanding characteristics of rich raw materials, mature manufacturing process, low price, and wide application. It is the second largest general-purpose resin in the world market after polyethylene in terms of output and demand. The processing technology of polyvinyl chloride is simple, and it has great advantages in performance and price. It plays a very important role in industrial production and is widely used in industries such as industry, agriculture, construction, transportation, electric power, telecommunications and packaging. However, due to the poor thermal stability and heat resistance of PVC, the plasticizing effect is unstable, and it is easy to volatilize and migrate. When preparing hard p...
