Abstract

The invention discloses a PVC decorative plate. The PVC decorative plate comprises following ingredients, by mass, 100 parts of PVC, 5 to 8 parts of MBS, 1 to 3 parts of carbon black, 2 to 4 parts of DOP, 50 to 80 parts of active heavy calcium carbonate, 4 to 6 parts of CPE, 1 to 5 parts of epoxidized soybean oil, 5 to 7 parts of tribasic lead sulfate, 2 to 5 parts of dibasic lead phosphate, 4 to 6 parts of a modifier, 1 to 4 parts of paraffin, 2 to 3 parts of barium stearate, and 0.5 to 1 part of lead stearate. Product relative density ranges from 0.9 to 0.95, bending strength ranges from 55 to 65MPa, impact strength ranges from 380 to 400MPa, tensile strength ranges from 80 to 85MPa, oxygen index ranges from 30 to 35%. The PVC decorative plate is high in hardness, is antistatic, can be used for replacing existing materials continuously, and large-scaled production is realized.

Description

technical field [0001] The application belongs to the field of plastic materials, in particular to a PVC decorative board. Background technique [0002] PVC decorative board has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardancy, and simple construction. There are many specifications, colors and patterns, and it is very decorative. It can be applied to the decoration of the interior wall and ceiling of the living room. It is one of the most widely used decorative materials in plastic materials; PVC decorative materials mainly include: PVC monochrome film decorative sheet , PVC high-temperature resistant cabin interior film, PVC transparent film, PVC vacuum-absorbing decorative film, PVC flat-stick decorative film, etc. [0003] PVC decorative board is light in weight, heat insulation, heat preservation, moisture proof, flame retardant, acid and alkali resistance, and corrosion resistance. Good stability and dielec...
