preparation example Construction

[0072]A preparation method of a polymer alloy adding wood (bamboo) powder and scale materials, comprising the steps of: 1. Preparation of surface modified metal flakes or glass flakes: adding dry flake glass or metal flakes to a high-speed mixer to mix, Add coupling agent, mix for 3-5 minutes, discharge for later use. 2. Processing of wood (bamboo) powder: Wood (bamboo) powder is stirred and dried in a high-speed mixer (preheated material temperature reaches 100-120°C) for 10-15 minutes, and dehumidified so that the water content of wood (bamboo) powder If it is less than 0.3 parts, add wood-plastic coupling agent, mix for 2-3 minutes, add pre-mixed glass flakes or metal flakes, mix for 3-5 minutes, then add impact modifier resin, mix for 3-5 minutes, The impact modifier resin is wrapped on the surface of wood (bamboo) powder and glass flakes or metal flakes, and the mixture of wood (bamboo) powder and glass flakes or metal flakes in the high-speed mixer is put into the cold m...

Abstract

The invention provides a polymer alloy with added wood (bamboo) powder and a flake material, which comprises the wood (bamboo) powder, a polymer material (ABS (Acrylonitrile Butadiene Styrene) / PVC (Polyvinyl Chloride) alloy, PC (Polycarbonate) / PE (Polyethylene) alloy, PP (Polypropylene), PE (Polyethylene), PVC (Polyvinyl Chloride), PS (Polystyrene), a coupling agent, an impact modifier, a stabilizer, a plasticizer, a foaming agent, a flame retardant, a compatilizer, a dispersing agent, a lubricating agent and an ultraviolet absorbent, wherein 5-35 parts by weight of surface modified flake glass or surface modified metal flake or surface modified organic resin flake and 15-40 parts by weight of the wood (bamboo) powder are added into the polymer material.

Description

Technical field: [0001] The invention relates to the field of polymer composite materials, in particular to a wood-plastic polymer alloy made of wood (bamboo) powder and glass flakes or metal flakes or organic resin flakes. Background technique: [0002] Wood-plastic polymer alloy material is a modified material filled with 20-60 parts of wood fiber thermoplastic polymer materials (PP polypropylene, PE polyethylene, PVC polyvinyl chloride, PS polystyrene), widely used in the field of architectural decoration, It has the advantages of wood and plastic, but due to the poor affinity between wood powder or bamboo powder and thermoplastics, wood (bamboo) powder is used as a polymer material (PP polypropylene, PE polyethylene, PVC polyvinyl chloride, PS polystyrene) ) filler, which reduces the mechanical properties and processing properties of wood-plastic polymer materials such as ductility and impact strength, especially thermoplastic polymer (PP polypropylene, PE polyethylene, ...
