Embodiment 1

[0017] A raw material for the preparation of a PVC-skinned foam board comprises the following components in parts by weight: 45 parts of PVC, 0.15 parts of coupling agent, 0.15 parts of stearic acid, 6 parts of wood flour, 1.5 parts of composite stabilizer, foam regulator 12 parts of agent, 0.8 part of fatty alcohol dicarboxylic acid ester, 1.7 parts of AC foaming agent, 12 parts of light calcium carbonate, 0.4 part of PE wax, and 0.1 part of tribasic lead sulfate.

[0018] The raw materials of wood flour include the following five types: sawdust, peanut shells, bagasse, coconut shells, and flax. The preparation method of the wood powder is as follows: the raw material of the wood powder is sterilized under ultraviolet rays for 10 minutes, and then ground to a fineness of 300-40 mesh. Foam regulator is a mixture of ACR530 and ACR401, the mixing ratio is 2:6.

Abstract

The invention relates to the technical field of plastic processing, in particular to a PVC crusted foaming board and a preparation method thereof. The PVC crusted foaming board comprises the followingpreparation raw materials: PVC, a coupling agent, stearic acid, wood powder, a compound stabilizer, a foaming control agent, fatty alcohol dicarboxylate, an AC foaming agent, precipitated calcium carbonate, PE wax and lead sulfate tribasic. A scientific formula is provided, the used wood powder is low in price, extensive in source and easy to prepare, the manufacturing cost is reduced, a manufactured PVC wood-plastic building template has good toughness and is unlikely to break, nano calcium carbonate is used as filler, and has small fineness and grain size, and the manufactured PVC wood-plastic building template is smooth and fine, and has good performance. Process conditions such as extrusion temperature and the rotating speed of a pressure screw of a machine head in a preparation process are strictly controlled, AND through test on the produced PVC crusted foaming plates, the performance meets the requirement for quality of Q / STNY001-95. The preparation method is simple, is easy tooperate and can be popularized widely.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a PVC-skinned foam board and a preparation method thereof. Background technique [0002] PVC foam board, also known as Chevron board and Andy board, is divided into two types: crust foam and free foam. PVC foam board is very widely used, because of its relatively low price and superior performance, it is increasingly popular with the public. According to the production process, PVC foam board can be divided into PVC co-extrusion foam board, PVC crust foam board and PVC free foam board. Among them, the surface hardness of PVC crust foam board is lower than that of PVC co-extrusion foam board, and it is difficult to produce scratches. It is widely used in cabinets and decorations. However, the current formula of PVC crust foam board is unscientific and the production process is complicated, which limits the output and development of the industry. Contents of the inven...
