Problems solved by technology

Combining the two, the peel strength of the obtained product is very small, the mechanical properties cannot meet the requirements, and the product is prone to "delamination" during use. If the PVC wood-plastic products and long fiber reinforced PP sheets cannot be solved well Compatibility of materials will greatly limit the application range of continuous long fiber reinforced thermoplastic sheets, affecting the social benefits of products

Embodiment 1

[0043] The composite process of PVC wood-plastic products and long-fiber reinforced thermoplastic sheets (PP sheets, the following examples and comparative examples are also long-fiber-reinforced PP sheets) includes the following steps:

[0044] 1) The long fiber reinforced PP sheet is subjected to surface flame treatment through a surface flame treatment device. The conditions for surface flame treatment are: the mixed gas used is a mixed gas with a volume ratio of natural gas and air of 1:1; the moving speed of the flame injection head: 200mm~500mm / s, the flame temperature: 1200~1500°C; the flame length : 5~15cm; the distance between the flame outlet and the sheet: 5~12cm;

[0045] 2) Spray the sheet prepared in the previous step evenly on the surface of the sheet through the spraying equipment, and the spraying amount is 0.1kg / m 2 , the compatibilizer is composed as follows in parts by mass: 40 parts of bisphenol A type epoxy resin, 33 parts of 203 polyamide, 11 parts of d...

Abstract

The present invention disclosed a compatible agent, which is composed of raw materials of the following quality portions: 30-45 copies of bisphenol A epoxy resin, 20-40 copies of 203 polyamide, and 8-11 copies.Tonyhamine, 0.3-3 parts of 2,4,6- trceseine (dihylamine-based) phenols, 1-5 parts of coupling agents, 10-30 copies of chlorine polypropylene solution, 50-60 partsTrifamol.A composite process of PVC wooden plastic products and long fiber enhanced thermoplastic plastic sheets, including the following steps: 1) Surface flame treatment of long fiber enhanced thermoplastic plastic sheets;Patients, then dry; 3) Squeeze the PVC wooden plastic particles with the sheets that are treated with upper steps.By adding consequences, the present invention greatly improves the interface compatibility of long fibers to enhance thermoplastic plastic sheets and PVC wooden plastic products, introduce long fibers into the final composite products, improve their mechanical properties, and the final preparation of the present invention prepared.The safety factor of composite products is high.

Description

technical field [0001] The invention relates to a composite process of PVC wood-plastic products and long-fiber reinforced thermoplastic plastic sheets. Background technique [0002] The surface of long fiber reinforced PP or PE sheet is weakly polarized, while PVC wood-plastic material is a material with strong polarity, and the two are incompatible. Combining the two, the peel strength of the obtained product is very small, the mechanical properties cannot meet the requirements, and the product is prone to "delamination" during use. If the PVC wood-plastic products and long-fiber reinforced PP sheets cannot be solved well If the material compatibility problem is not met, it will greatly limit the promotion of the application range of continuous long fiber reinforced thermoplastic sheet, and affect the social benefits of the product. Contents of the invention [0003] The object of the present invention is to provide a composite process of PVC wood-plastic products and l...
