Problems solved by technology

[0003] 1. Wood fiber or plant fiber needs special drying equipment for pretreatment before use, which is time-consuming and energy-consuming
[0004] 2. The wood fiber or plant fiber in the mixture is easy to absorb moisture. Although it has been dried, it is still not suitable for storage and can only be mixed and used now.
[0005] 3. Affected by factors such as raw material suppliers and processing technology, the quality of products produced by different manufacturers with the same formula varies greatly
[0006] 4. The density of processed products is relatively high, usually exceeding 1.1-1.4g / cm 3 , the practical application is restricted by

Abstract

The invention discloses a PVC wood-plastic low foaming granule material and a preparation method thereof, and belongs to the technical field of wood-plastic materials. The PVC wood-plastic low foaming granule material comprises the following substances in portion by weight: 20 to 60 portions of wood powder or / and bamboo powder, 100 portions of polyvinyl chloride, 2 to 12 portions of composite stabilizing agent, 5 to 60 portions of CaCO3, 0.6 to 6 portions of foaming agent, 2 to 16 portions of assistant foaming agent, 1 to 10 portions of processing assistant, 0.6 to 6 portions of lubricating agent, 0.6 to 4 portions of coupling agent, and 0.1 to 0.8 portion of paint. The method for preparing the PVC wood-plastic low foaming granule material comprises the following steps: mixing and heating the substances; plasticizing the substances; extruding the substances into columnar granules; and separating and packing the granules as a product. The PVC wood-plastic low foaming granule material has relatively stable components and lighter texture, and is convenient to transport, store and process. The preparation method is simple and practical, saves energy, and saves investment; and the quality of the product is stable.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic materials, and relates to a new type of wood-plastic low-foaming granular material compounded with wood powder or / and bamboo powder, polyvinyl chloride (PVC) and processing aids; and the new type A preparation method of wood-plastic low-foaming granules. Background technique [0002] Wood-plastic material is a new type of composite material obtained by filling, reinforcing, modifying and blending waste wood fibers or plant fibers and thermoplastics. This mixed modified material can be processed into shaped materials, plates or other products through a special single-screw extruder or twin-screw extruder with corresponding molds and auxiliary molding machines. There are following defects in the currently available wood-plastic granules and their processing methods: [0003] 1. Wood fiber or plant fiber needs special drying equipment for pretreatment before use, which is time-consuming and en...
