Special active solvent for producing grains on surface of PP (Polypropylene) wood plastic product

Abstract

The invention discloses a special active solvent for producing grains on the surface of a PP (Polypropylene) wood plastic product. The special active solvent is prepared from the following raw materials in weight proportion: 30 to 45g of dimethylbenzene, 2 to 10g of dichloromethane, 5 to 12g of ketone, 20 to 30g of butanone, 10 to 20g of cyclohexanone, 5 to 15g of isobutanol and 5 to 15g of methyl acetate. Compared with the prior art, the invention provides the special active solvent for specially producing the grains on the surface of the PP wood plastic product; when the active solvent is combined with a hydraulic fracturing attaching process, patterns on a printed film are clear and are firmly attached to the surface of a wood plastic product blank, and an adhesive force reaches 0 grade; the obtained grains on the surface of the wood plastic product are realistic in effect, and are smooth and clean in surface; in addition, a film of the obtained product is higher in hardness (can reach 6H or higher) and is better in wear resistance (a wear value g/100r is smaller than or equal to 0.01).

Description

technical field [0001] The invention relates to wood-plastic composite material products, in particular to a special active solvent used for making surface textures of PP wood-plastic products. Background technique [0002] Wood-plastic composite material is a new type of environmentally friendly material prepared by mixing biomass materials such as crop straw, wood powder, and wood fiber with polymer materials obtained from waste plastics in proportion to a certain process. Recycling of industrial materials. Wood-plastic composite materials have the advantages of both biomass materials and polymer materials, so they are widely used in packaging, warehousing, urban construction and architectural decoration industries. [0003] There are mainly the following types of decoration for wood-plastic composite materials: ①Processing colored profiles, that is, adding a certain colorant to the wood-plastic composite material batching process to achieve the effect of decoration, but ...
