Problems solved by technology

Although PVC foam board has such a wide application space, there are still some defects that limit its use, and its actual market share is low. The PVC foam board currently used mainly has the problem of not being resistant to high temperatures, and it is easy to deform at high temperatures. Cracking and brittle fracture will affect its application, and it cannot be fireproof, which has potential safety hazards

Abstract

The invention discloses a fireproof and high-temperature-resistant polyvinyl chloride (PVC) foam board and a preparation method thereof, belonging to the technical field of production of PVC foam boards. The fireproof and high-temperature-resistant PVC foam board is prepared from the following raw materials in parts by weight: 100 parts of PVC with an average polymerization degree of 800-1000, 2-7parts of a foaming regulator, 0.5-0.9 part of a foaming agent, 2-7 parts of methyl octabromo ether, 1-5 parts of aluminum dioxide, 5-10 parts of polyiso-melamine ester, 2-5 parts of dibutyltin maleate, 3-5 parts of a calcium-zinc composite stabilizer, 5-8 parts of wood chips, 35-40 parts of calcium carbonate, 10-15 parts of talcum powder, 0.6-0.8 part of an internal lubricant 60, 0.6-0.8 part ofan external lubricant liquid paraffin and 40-50 parts of dioctyl phthalate. By adding a fire retardant and a thermal insulation material into a production formula of the PVC foam board, the prepared PVC foam board has good high temperature resistance and fire resistance.

Description

technical field [0001] The invention relates to the technical field of PVC foam board production, in particular to a fireproof and high temperature resistant PVC foam board and a preparation method thereof. Background technique [0002] PVC foam board is a new type of green and environmentally friendly material. It has the characteristics of light weight, flame retardant, acid and alkali resistance, moisture resistance, waterproof, heat preservation, sound insulation, shock absorption, etc. The surface can be printed, coated or made into various colors. Widely used in ships, train manufacturing, furniture production, decoration, silk screen printing and production of advertising industry, etc. Compared with traditional wood, PVC foam board has various processing properties of wood and is superior to wood. , an ideal substitute for composite panels. Although PVC foam board has such a wide application space, there are still some defects that limit its use, and its actual mark...
