Aromatic multi-texture microporous thermoplastic resin wood-imitating materials and wood texture forming process

Abstract

The new thermoplastic resin pseudo-wood material can be got by the following steps: taking polychloroethylene as main material, light calcium carbonate as filler, adding elasticizer, stabilizer, lubricant, modifier as process adjuvants, and colorant, flavoring agent and activator to mix, granulate and extrusion mould, then surface treating them. Wherein blowing agent and elasticizer are azobisformamide, dioctyl phthalate; blowing modifier is ZB530; the flavouring agent is for flavouring; leadless heat stabilizer is calcium-magnesium-zinc compounds. The material not only is provided with the advantage of all old theromplastic resin pseudo-wood material, but also good plasticizing effect; homogeneous micropores; plump corners; smooth surface; the scent relieves slowly; environmental protection without toxic, especially for the hydrostatic pressure test adhesion craft, and the product surface is of colourful grain motif, natural and slight grain, resistance to abrasion, never decolour, acid / alkaliproof, no drop, no molding, and luxury. It can be used for house furnishings decorative construction material, as well as for high-grade luxury furnishing.

Description

(1) Technical field: [0001] The invention relates to a polymer imitation wood material composition, in particular to an aromatic multi-grain microporous thermoplastic resin imitation wood material and its surface wood grain formation process. (two) background technology: [0002] At present, there are many imitation wood products made of thermoplastic resin imitation wood materials on the market. Due to the formula and production process of each manufacturer, that is, after mixing two or more different color pellets, according to the flow rate The difference is that one-time extrusion into imitation wood grain materials generally has distortion of the wood grain of the product. The surface wood grain of existing products is generally produced by printing, heat transfer printing or film coating technology. Ink printing grade is low, thermal transfer is not wear-resistant, easy to fade, the film is easy to foam, degumming and peeling off, and the one-time extrusion line is uns...

Problems solved by technology

[0002] At present, there are many imitation wood products made of thermoplastic resin imitation wood materials on the market. Due to the formula and production process of each manufacturer, that is, after mixing two or more different color pellets, according to the flow rate The difference is that one-time extrusion into imitation wood grain materials generally has distortion of the wood grain of the product. The surface wood grain of existing products is generally produced by printing, thermal transfer or film coating technology.

Ink printing grade is low, thermal transfer is not wear-resistant, easy to fade, the film is easy to foam, degumming and peeling off, and the one-time extrusion line is unstable, the color is not coordinated, the color difference is serious, not delicate, the line is rough and single, and the appearance is dull. Defects such as lack of light; especially when using it to make products with uneven and complex curved surfaces with dead corners, it is difficult to achieve the simulation effect with printing, thermal transfer, and lamination technologies

The bigger problem is that the existing products generally contain lead and are poisonous, easy to age and fade, low in strength, brittle at low temperature, easy to deform in high temperature environment, poor in hardness, easy to scratch, not wear-resistant, and cannot maintain bright color for a long time. Unnatural appearance, no luxurious quality, no fragrance, people are reluctant to use it to replace natural wood for indoor and outdoor decoration, thus limiting the promotion and application of plastic instead of wood products
