Problems solved by technology

[0003] However, the existing plastic-wood panels generally do not have good flame retardancy, and the mechanical strength of the plastic-wood panels prepared by the preparation method is not satisfactory, which cannot meet the needs of the existing society. Therefore, we propose a flame-retardant Combustion-plastic-wood composite material board and preparation method thereof

Embodiment 1

[0030] The present invention also provides a method for preparing a flame-retardant wood-plastic composite board, comprising the following steps:

[0031] S1. Choose wood powder, recycled PE plastic granules, fillers, fireproof filler granules, flame retardants, antifungal agents, and lubricants as raw materials. The formula of the raw materials by weight is as follows: 70 parts of wood powder, 40 parts of recycled PE plastic granules , 15 parts of filler, 10 parts of fireproof filler particles, 3 parts of flame retardant, 1 part of antifungal agent, 1 part of lubricant;

[0032] S2. Put wood powder, recycled PE plastic particles, and fillers into a ball mill for grinding in proportion to obtain a grinding powder with a mesh number not greater than 30 mesh, and then mix the ground powder with the same proportion of components Fireproof filler particles, flame retardants, antifungal agents, and lubricants are artificially batched, and put into a mixer for stirring and mixing. T...

Abstract

The invention relates to the technical field of plastic-wood composite materials, especially to a flame-retardant plastic-wood composite sheet. The flame-retardant plastic-wood composite sheet includes a core base layer, in which a reinforced layer is embedded. The reinforced layer and the core base layer are an integrated structure. Two sides of the core base layer are respectively fixedly connected to an upper protective layer and a lower protective layer. The invention also provides a preparation method of the flame-retardant plastic-wood composite sheet. The flame-retardant plastic-wood composite sheet has a good flame-retardant effect, low production cost and high mechanical strength. In addition, construction and operation of the sheet are flexible. By extruding two sides of the reinforced layer, the reinforced layer and the core base layer are blended into a whole body. The extrusion method is simple and feasible, and the product has good mechanical strength.

Description

technical field [0001] The invention relates to the technical field of plastic-wood composite materials, in particular to a flame-retardant plastic-wood composite material board and a preparation method thereof. Background technique [0002] Wood-plastic materials are widely used in building materials, furniture, logistics packaging and other industries. In these industries, fire resistance is particularly important, because once a fire occurs, it will cause devastating disasters. [0003] However, the existing plastic-wood panels generally do not have good flame retardancy, and the mechanical strength of the plastic-wood panels prepared by the preparation method is not satisfactory, which cannot meet the needs of the existing society. Therefore, we propose a flame-retardant Burnt-plastic wood composite board and its preparation method. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a flam...
