Abstract

The invention discloses a high-flame-retardance polyvinyl chloride resin, and belongs to the technical field of resin preparation. The high-flame-retardance polyvinyl chloride resin comprises: a polyvinyl chloride resin, an epoxy resin, a phenolic resin, poly(phenylene oxide), an EVA resin, diethylene glycol phthalic anhydride polymer, ethylene-vinyl acetate copolymer, trioctyl trimellitate, styrene, dicumyl peroxide, tritolyl phosphate, polycaprolactone, talcum powder, zinc stearate, cerium oxide, antimonous oxide, wood fiber powder, glass fiber, aluminium triphosphate, zinc borate, chlorinated paraffin, epichlorohydrin, maleic anhydride, magnesium hydroxide, a silicane coupling agent KH-560, and a flame-retardant modification auxiliary agent. The high-flame-retardance polyvinyl chlorideresin is made through base material preparation, modification material preparation, and mixing of base materials and modification materials. The prepared polyvinyl chloride resin is excellent in flameretardance.

Description

technical field [0001] The invention relates to the technical field of resin preparation technology, in particular to a high flame-retardant polyvinyl chloride resin and a preparation method thereof. Background technique [0002] PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2 / 3 of the market, and soft PVC accounts for 1 / 3. Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains a softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use is limited. Rigid PVC does not contain softeners, so it has good flexibility, easy to shape, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. Hereinafter referred to as PVC. The essence of PVC is a vacuum blister film, which is used for the surface packaging of various panels, so it is also calle...
