AI Technical Summary

Technical Problem

Existing wood-plastic panels have deficiencies in light color, antioxidant properties, UV resistance, and hard texture of the panels, making it difficult to meet high-demand application needs.

Method used

It uses a lubricant mixed with zinc stearate, paraffin wax and ethylene bisstearamide, a phase solvent mixed with maleic anhydride-grafted PP and maleic anhydride-grafted PE, and additives of talc powder and sulfuric acid powder. A new formula is created by combining non-pine wood flour with a specific ratio of moisture and ash powder.

Benefits of technology

It significantly improves the anti-oxidation, anti-ultraviolet performance and hardness of the wood-plastic board, enhances the gloss, and improves the fluidity of the wood powder, making the board excellent in gloss, anti-oxidation and anti-aging.

Abstract

The invention relates to a formula for the wood-plastic sheet material and relates to the technical field of wood-plastic sheet material production. The wood-plastic sheet material comprises the following components: plastic particles, wood flour, lubricants, phase solvents, additives, anti-ultraviolet agents, oxidation inhibitors, anti aging agents and toners. The wood-plastic sheet material provided by the invention is better in oxidation resistance, uvio resistance, as well as the rigidity and the glossiness of the sheet material; the wood-plastic sheet material mainly has the following characteristics: the mixture of double phase solvents is adopted to carry out miscibility; moreover, the lubricating components inside the lubricant are uniformly mixed by three lubricating components, so that the lubricants have the effect of three types of lubricants and the flowability of the wood flour can be greatly increased. Therefore, the rigidity of the wood-plastic sheet material can be excellently lifted and the effects on glossiness, oxidation resistance and aging resistance are remarkable.
