The wood plastic plate coated by the silicone flame retardant coating has the advantages that: the coated silicone flame retardant coating has the advantages of low density, high mechanical strength, low suction and ventilation property, heat resistant, flame retardant property, etc. Secondarily, positive effects are brought to the application of the wood plastic plate coated by the silicone flame retardant coating; therefore, the smoke volume and corrosive gas volume of the wood plastic plate during combustion are greatly reduced and the environmental pollution is reduced.
Description
Technical field
What the present invention relates to is a kind of Wood plastic boards that applies the silicon flame retardant coating, belongs to the Wood plastic boards technical field.
Background technology
It is primary raw material manufacture that Wood plastic boards be take lignocellulosic material and plastics.Just because of Wood plastic boards, many advantages are arranged, as good water-fast and decay resistance, good stability of the dimension, production technology are flexible, infringement to equipment is little, can also be that raw material makes with the waste and old wood and the plastics that reclaim, and can be recycled etc., Wood plastic boards is as a kind of novel engineering material, all have a wide range of applications in a lot of fields, such as the construction material of door and window, floor, wall, fence material, automotive material etc.At present, adopt in Wood plastic boards the mode of adding fire retardant to improve the anti-flammability of Wood plastic boards more, namely first to wood fibre carry out drying, pulverization process becomes wood powder, then wood powder is carried out to modification, finally carry out again polymerization and generate recycled wood.Such as aluminium hydroxide, Firebrake ZB etc., non-poisonous material pollutes although have advantages of, but for the very high polymer composite of loading especially wood plastic composite, also there is very large inferior position, because this just needs very high loading this based flame retardant in matrix, usually want more than 60% in order to reach suitable fire resistance addition.The interpolation content that fire retardant is high not only causes the high density of final products and the disappearance of elastic performance, and can bring mixing, extrudes the problem of aspect.
Summary of the invention
What the present invention proposed is a kind of Wood plastic boards that applies the silicon flame retardant coating, its purpose is intended to overcome the existing above-mentioned defect of prior art, utilize the composite flame retardant system of the compositions such as silicon-series five-retardant and organic resin to carry out the surface coating to Wood plastic boards, to reach the halogen-free flameproof modification, sheet material is had fire-retardant, delay the characteristics of sheet material burning.
Technical solution of the present invention: it is characterized in that the surperficial applied thickness at Wood plastic boards is the silicon flame retardant coating of 0.3mm, the preparation method of its silicon flame retardant coating: 1) get raw material, its composition by weight: resin 20-35 part, silicon fire retardant 25-45 part, fire retarding synergist 8-12 part, color stuffing 6-10 part; 2) grind, utilize mortar to make its solid constituent levigate, and cross 325 mesh sieves; 3) utilize constant temperature blender with magnetic force at 60 ℃ of lower high-speed stirred 30min, it is mixed; 4) with brush, along the direction in length and breadth of Wood plastic boards, apply equably, make coating layer thickness reach 0.3mm, made fire resistance period reach 35min in dry 24 hours.
Advantage of the present invention: the silicon flame retardant coating of coating has that density is little, mechanical strength is high, air-breathing gas permeability is low, heat-resisting and the advantage such as fire resistance, next is to apply and brought good effect to the Wood plastic boards of coating silicon flame retardant coating, be that Wood plastic boards generates when burning cigarette amount and corrosive gas amount reduces greatly, environmental contamination reduction.
