Abstract

The invention relates to the technical field of plastic processing, in particular to a polyvinyl chloride (PVC) free foaming board and a preparation method thereof. The PVC free foaming board is prepared from the following raw materials: 95 to 100 parts of PVC, 1 to 3 parts of a calcium-zinc stabilizer, 2 to 4 parts of an enhancer, 6 to 15 parts of a foaming control agent, 1 to 4 parts of a foaming agent, 1 to 2 parts of a lubricating agent, and 50 to 80 parts of filler. The PVC free foaming panel prepared by adopting a formula and the method provided by the invention has the shore D harness reaching 45 to 50, is not easy to crack and is resistant to tension; through strictly controlling the temperature and the rotating speed, the excellent foaming agent is selected, and no foam breaking phenomenon occurs, so that the board has good performance and meets the use requirement.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a PVC free foam board and a preparation method thereof. Background technique [0002] PVC free foam board is a kind of PVC foam board. According to the production process, PVC foam board can be divided into PVC crust foam board and PVC free foam board. PVC foam board is also called Chevron board and Andy board, and its chemical composition is polyvinyl chloride. Its chemical properties are stable. Acid and alkali resistance and corrosion resistance! Moisture-proof and mildew-proof, thermal insulation, sound-proof and sound-absorbing, flame-retardant and self-extinguishing, smooth surface, moth-proof, light weight, and non-absorbent. The surface hardness of PVC free foam board is average, and it is widely used in advertising display boards, picture boards, silk screen printing, engraving, etc. However, there is no scientific and systematic preparation method at pres...
