Abstract
The invention relates to a high polymer material and a preparation method thereof, particularly a halogen-free flame-retardant wood-plastic composite material and a preparation method thereof. The halogen-free flame-retardant wood-plastic composite material is prepared from 20-30 parts of polyethylene resin, 50-60 parts of wood powder, 20-30 parts of compound halogen-free flame retardant, 1-3 parts of compatilizer PE-g-MAH (polyethylene grafted maleic anhydride), 0.5-1 part of antioxidant 1010, 0.5-1 part of antioxidant 168, 2-5 parts of lubricant and 0.5-1 part of anti-ultraviolet agent. The preparation method comprises the following steps: proportionally mixing red phosphorus, magnesium hydroxide and aluminum hydroxide; mixing with polyethylene resin, wood powder, graft and other processing assistants by a high-speed mixer; extruding with a double screw extruder to carry out granulation; and extruding and forming with a conical double screw extruder. The halogen-free flame-retardant wood-plastic composite material product produced by the method provided by the invention has excellent flame retardancy, such as self-extinguishing after leaving fire, small smoking amount and the like, and can achieve the flame-retardant grade V-0 in vertical burning testing. The invention has the advantages of simple technical route and stable product quality, and is suitable for industrial production.
Description
Technical field
The present invention relates to a kind of macromolecular material and preparation method thereof, particularly relate to a kind of halogen-free flame-retardant wood-plastic composite material and preparation method thereof.
Background technology
Wood plastic composite (WPC) is take wood powder as main raw material, makes itself and the compound green material that becomes high-performance, high added value of plastics not of the same race through suitable processing.In recent years increasingly exhausted with global resources, social environment consciousness is day by day surging, and timber and petroleum chemicals application have been proposed requirements at the higher level.Under such background, this advantage that can bring into play each component in the material of wood plastic composite, overcome, variability low because of strength of wood and reach greatly the organic materials Young's modulus use limitation that causes such as low, can take full advantage of again discarded timber and plastics, environmental contamination reduction.
Wood plastic composite combines the advantage of timber and plastics, now has been widely used in the aspects such as automotive industry, building trade and transport trade.Its principal feature has: (1) is durable, the life-span is long, and similar wood appearance is arranged, and is higher than plastics hardness; (2) have good physical property, better than wood dimensional stability, can not produce crack, warpage, without timber knot, twill, add tinting material, overlay film or composite skins and can be made into various goods lucuriant in design; (3) processibility of thermoplastics is arranged, easily moulding, with general device of plastic processing or just can carry out forming process after the transformation a little, easy to utilize; (4) secondary processing generation of similar wood is arranged, can cut, bonding, be connected and fixed with nail or bolt, paintable, the product specification shape can be according to the customer requirements adjustment, and handiness is large; (5) be not afraid of and damage by worms, ageing-resistant, corrosion-resistant, water-absorbent is little, can hygroscopic deformation; (6) can reuse and recycling environmental friendliness; (7) maintenance cost is low.
But, because main raw material vegetable fibre and plastics (particularly polyolefin plastics) in the wood plastic composite all are flammable inflammable materials, therefore, wood plastic composite does not possess flame retardant resistance, have security against fire hidden danger, this shortcoming has limited the application of this Green Product in suitable degree.
At present wood plastic composite fire-retardant are adopted morely and traditional polymkeric substance is carried out fire-retardant technology, there is no the characteristics of noticing that wood plastic composite self has, the flame retardant effect of therefore obtaining is bad, and perhaps cost performance is too low.How developing a kind of flame-retarded technology that is applicable to wood plastic composite is a problem demanding prompt solution.
Summary of the invention
The object of the present invention is to provide a kind of halogen-free flame-retardant wood-plastic composite material and preparation method thereof.The halogen-free flame-retardant wood-plastic composite material product that present method is produced has from the flame retardant properties of fire from excellences such as putting out, the amount of being fuming is little, can reach the fire-retardant rank of V-0 level of vertical combustion test, solves the ubiquitous fire-retardant problem of wood plastic composite on the market.
The objective of the invention is to be achieved through the following technical solutions:
A kind of halogen-free flame-retardant wood-plastic composite material, the component of this halogen-free flame-retardant wood-plastic composite material and parts by weight are: polyvinyl resin 20-30 part, wood powder 50-60 part, Compositional type halogen-free flame retardants 20-30 part, compatilizer PE-g-MAH is that polyethylene connects maleic anhydride 1-3 part, antioxidant 1010 i.e. four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester 0.5-1 part, irgasfos 168 is three (2, the 4-di-tert-butyl-phenyl) phosphorous acid ester 0.5-1 part, lubricant 2-5 part, anti UV agent 0.5-1 part.
Described a kind of halogen-free flame-retardant wood-plastic composite material, the Compositional type halogen-free flame retardants is the mixture of red phosphorus and magnesium hydroxide, aluminium hydroxide in the described halogen-free flame-retardant wood-plastic composite material, wherein the parts by weight of red phosphorus are 5-8, the parts by weight of magnesium hydroxide are 5-20, and the parts by weight of aluminium hydroxide are 3-12.
A kind of preparation method of halogen-free flame-retardant wood-plastic composite material, described method comprises following process: red phosphorus and magnesium hydroxide, aluminium hydroxide proportionally are mixed to get the Compositional type halogen-free flame retardants, then obtain a kind of halogen-free flame-retardant wood-plastic composite material with polyvinyl resin, wood powder, grafts and other processing aids through high mixer batch mixing, twin screw extruder extruding pelletization, conical double screw extruder extrusion moulding step.
Advantage of the present invention and effect are:
1. the halogen-free flame-retardant wood-plastic composite material product of the inventive method production has from the flame retardant properties of fire from excellences such as putting out, the amount of being fuming is little, can reach the fire-retardant rank of V-0 level of vertical combustion test.
