Embodiment Construction

[0029] The invention discloses a foamed stone-plastic wood board, which is prepared by extruding the following raw materials with the following weight ratios:

[0030] 100 parts of polyvinyl chloride,

[0031] 50-60 parts of plant powder,

[0032] 40 parts of calcium carbonate,

[0033] 1.6 parts of blowing agent,

[0034] Foam regulator 12 parts,

[0035] 4 parts lubricant,

[0036] 3 parts of coupling agent,

[0037] Antioxidant 0.2 part,

[0038] 7 parts of anti-shock filler.

[0039] Preferably: the polyvinyl chloride is SG-5 type; the plant powder includes 40-70% corn husk fiber powder; the balance is wood powder; the calcium carbonate is light calcium carbonate; The lubricant is one of stearic acid or polyethylene wax; the antioxidant is 2,6-di-tert-butyl-4-methylphenol or tri-(2,4-tert-butylphenyl) One of phosphite esters; the coupling agent is one of silane coupling agent or titanate coupling agent, and the anti-impact filler is acrylic ester filler. Wherein f...

Abstract

The invention discloses a foaming type stone plastic wood panel which contains 100 parts of polyvinyl chloride, 50-60 parts of plant powder, 40 parts of calcium carbonate, 1.6 parts of foaming agent,12 parts of foaming regulator, 4 parts of lubricant, 3 parts of coupling reagent, 0.2 part of antioxidant and 7 parts of shock-resisting filler. The invention also discloses a preparation method for the foaming type stone plastic wood panel. The preparation method comprises the steps of preparing plant powder, mixing, extruding, coating a film, and the like. The polyvinyl chloride plastic wood panel disclosed by the invention has the characteristics of low density, low cost, high fire resistance, excellent smoke-suppressing property, high hardness and strong wood texture. The product accordingto the invention is low-carbon, energy-saving and environment-friendly, is beneficial to implementation of resource conservation, is capable of facilitating ecological construction, is reusable and is suitable for sustainable development. The panel disclosed by the invention has excellent bonding property with PUR rubber, the peeling force of the bonded base layer and the surface layer is strong,the surface bonding strength is high and the panel is difficult to crack.

Description

technical field [0001] The invention relates to a polyfoamed stone-plastic wood board and a preparation method thereof, belonging to the technical field of polyvinyl chloride boards. Background technique [0002] my country lacks forests and trees, and resources are scarce. To develop a low-carbon society, protect the environment, protect ecological balance, and protect forest resources today and tomorrow, what materials to use to replace existing decorative materials has become a problem we have to consider. [0003] In addition, the existing materials also have the following disadvantages. The preparation process contains a large amount of adhesive, which is not conducive to environmental protection, consumes a large amount of wood, wastes forest resources, and has insufficient adhesion between the base material and the decorative surface. [0004] Therefore, it is necessary to propose a foamed stone-plastic-wood composite board with a hollow structure that uses low-grade...
