Problems solved by technology

[0005] However, the current wood-plastic materials still have many performance deficiencies and cannot completely replace wood, which limits the application of products in this industry in the domestic market. For example, wood-plastic materials with PE and PP substrates have relatively high density and self-creep Large, not suitable for applications such as building exterior walls
After PS, ABS, PVC and other base materials are foamed, in outdoor applications, the weather resistance is poor, and the application is greatly limited. At the same time, the material toughness is poor, and the strength is lower than that of PE and PP base material plastic wood materials.
Other co-extruded wood-plastic products developed in the past two years, such as wood-plastic co-extruded metal materials and wood-plastic co-extruded modified plastics, can partially solve the above problems, but the production process is cumbersome and the product rejection rate is high. There are two problems in use. Layer material detachment risk

Abstract

The invention provided an ASA plastic-wood material. The ASA plastic-wood material comprises the following components in percentage by mass: 70-90% of ASA plastic particles, 0.3-1% of a foaming agent, 10-30% of wood flour, 2-5% of a compatilizer and 1-4% of a lubricant. Because the wood flour used for preparing the ASA plastic-wood material is treated by an additive, the combinability and interface compatibility of the wood four and the ASA can be enhanced, the quality of the product can be improved, and thus the ASA plastic-wood material has great popularization value.

Description

technical field [0001] The invention relates to the field of building material preparation, in particular to an ASA plastic wood material and a preparation method thereof. Background technique [0002] "Wood-plastic material", also known as "wood-plastic composite material", as the name implies, can be understood as mainly plastic (polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), PS, ABS and other thermoplastic or recycled plastics. ) as raw materials, by adding wood powder, rice husk, straw and other waste plant fibers to mix into new wood materials, and then through extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. [0003] The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. Because WPC has both the water-resistant and a...
