Abstract

The invention provides a polyvinylchloride (PVC) plastic wood plank and a preparation method thereof. The PVC plastic wood plank consists of the following ingredients: PVC, calcium carbonate, wood flour, azodicarbonamide (AC) foaming agents, stabilizing agents, coupling agents, acrylicester (ACR), paraffin wax, stearic acid and fire retardants. By means of the PVC plastic wood plank, appending proportion of the calcium carbonate is enhanced by reducing the amount of the wood flour, and at the same time, by adjusting the amount of the PVC, and the type and amount of other additives, not only can hardness of the plank be greatly enhanced, but also appropriate toughness can be possessed. Therefore, the plank is guaranteed to be not only possess enough hardness when used as wood floors in public places so that damage and sinking of the surface of the plank are not prone to occurring, but also meet requirements of the wood floors due to the toughness of the plank so that the plank can be ensured to be not easy to crack.

Description

technical field [0001] The invention belongs to the field of plastic-wood boards, and in particular relates to a PVC plastic-wood board and a preparation method thereof. Background technique [0002] PVC wood-plastic board is a board made of wood powder (or straw powder), thermoplastic polymer material PVC and processing aids, mixed evenly and then heated, extruded and formed by mold equipment. Comparing with the traditional pure wooden board, it has the advantages of no formaldehyde, benzene and other toxic substances, environmental protection and renewable, no radiation, strong decoration and reasonable price. Has a very broad market prospects. [0003] In the prior art, the raw materials used to prepare PVC plastic-wood boards, in addition to PVC and wood powder, are usually added with calcium carbonate, foaming agent, plasticizer, stabilizer and lubricant. In order to obtain a PVC plastic sheet with better performance, those skilled in the art have made various attempt...
