Abstract
A wooden powder/PVC composite material and its production are disclosed. The composite material consists of PVC 58wt%, composite stabilizer 2.5-3wt%, CPE 7wt%, ACR-401 1-1.5wt%, AC foaming agent 1-1.5wt% and wooden powder 29-33wt%. It's convenient, has better water-proofing and fire-proofing functions and can be used for kitchen and toilet.
Description
One, technical field:
The present invention relates to a kind of building and ornament materials, a kind of wood powder/PVC matrix material is particularly disclosed, be applied to fields such as building decoration and packing, be particularly useful for indoor suit doors and indoor and outdoor decorative building material, have functions such as waterproof, fire-retardant, mildew-resistant, corrosion-resistant, environmental protection, electrical isolation.
Two. background technology:
Along with developing rapidly of China's high-rise, fire-retardant materials such as indoor suit doors material miscellaneous, matrix material constantly emerge in large numbers.But owing to have now in the plastics reinforcing filler on the market, be lime carbonate and glass fibre mostly, account for 40% and 31% respectively, and some other mineral fillers such as talcum powder, glass microballon etc., these traditional fillers make mixture that very big performance variation take place, and the cost of these fillers is higher.In in the past several years, some natural organic reinforcing fillers such as cellulose wadding are penetrated into this field just gradually, because their advantage is more than many general mineral fillers, are easy to get as raw material, cost is low, and density is little, and the wearing and tearing of equipment are few, the raw material reusable edible, pollution-free, degradable etc.In addition, substituting mineral filler with these organic fillers can significantly reduce product weight, reduces cost, but can not reduce the rigidity of mixture.Wood fibre is the most remarkable in these cellulose waddings, is used just widely.Wood powder/PVC matrix material grows up just on this basis.
Three. summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of have waterproof, fire-retardant, mildew-resistant, corrosion-resistant, environmental protection, electrical isolation are provided, both can be used for indoor suit doors and produced material, can be used for all kinds of indoor and outdoor decorative building materials again.
The present invention is achieved in that a kind of wood powder/PVC matrix material, it is characterized in that the proportioning (counting by weight percentage) of its composition material is:
PVC 58％，
One package stabilizer 2.5-3%,
Rare (CPE) 7% of chlorinated polyethylene,
Acrylic acid anti-impact agent (ACR-401) 1-1.5%,
AC whipping agent 1-1.5%,
Wood powder 29-33%;
Above raw material is commercially available,
Its production technique is: earlier PVC is put into high-speed mixer by prescription, when temperature to 60 ℃, add one package stabilizer (when referring to cold pot, PVC stirs and can add a stablizer in during as the heat pot), add chlorinated polyethylene rare (CPE), acrylic acid anti-impact agent (ACR-401) in the time of 80 ℃, add wood powder in the time of 100 ℃, to 110 ℃-115 ℃ can blowing cold mixing, add the AC whipping agent during to 50 ℃.With the mould material particle that mixes through single screw rod or twin screw extruder extruding pelletization, Heating temperature (is example with " 65 " twin screw extruder) is set earlier, one district (140-145 ℃), two districts (145 ℃-150 ℃), three districts (140 ℃-145 ℃), four districts (145 ℃-150 ℃), head (140 ℃-145 ℃), mouthful mould (150 ℃-155 ℃), current control is at (45A-50A), 30 rev/mins of engine speeds, blanking machine rotating speed coupling is carried out wood and is moulded particle and extrude.Wood is moulded particle through single screw rod or twin screw extruder extrusion moulding, Heating temperature (is example with " 65 " twin screw extruder) is set earlier, one district (120-125 ℃), two districts (125 ℃-1350 ℃), three districts (130 ℃-135 ℃), four districts (135 ℃-140 ℃), head (145 ℃-150 ℃), mouthful mould (150 ℃-160 ℃), after temperature is provided with, heat, behind design temperature, low speed start after being incubated half an hour, according to the melt situation, progressively adjust temperature and engine speed, carry out extrusion moulding again and be processed into product, check, warehouse-in.
The advantage of implementing after this technology is: cast off the shortcoming of log once and for all, improved the deficiency of log, kept the distinctive woodiness touch of log.Than timber, wood powder/PVC micro foaming composite material has waterproof, fire-proof function, thereby can be used for the decoration of kitchen, washroom etc., simultaneously, has all safety performances of log: but can follow closely, can create japanning (can select to exempt from lacquer).Especially suitable mass-producing, industrial fast quick-mounting are repaiied, and be efficient and convenient.The erosion resistance of wood powder itself is relatively poor, but is coated by macromolecular material, and polyvinyl chloride itself has good soda acid inertia, so this material has good erosion resistance.
