Abstract

A plastic-wood board contains PVC (45-48%), wood powder (38-40%), TiO2 or calcium carbonate as inorganic filler (6-7%), amide glucobistearate (0.8-1%), polyvinyl wax (0.3-0.5%), AC 629 (ethylene oxide) (0.5-0.8%), calcian stearate (0.7-0.8%), isooctyl bioctyl tin thioacetate (0.9-1%), ACR-401 (3-4%) and pigment at option.

Description

Plastic wood sheet

Field that the present invention belongs to

The invention belongs to polyvinyl chloride and wood powder is the section bar of main component.

The prior art background

Plastic wood sheet of the prior art particularly is the plastic wood sheet of main component with the polyvinyl chloride, because polyvinyl chloride belongs to hydrophobic material, and wood powder belongs to hydrophilic material, and the two is difficult to reach even when mixing.Therefore make sheet material the quality high standard that can not be consistent.

The purpose of invention

The objective of the invention is to propose a kind of is the new component technical scheme of the plastic-wood section of main component with polyvinyl chloride and wood powder, solves the problem that prior art exists.

The content of invention

Plastic wood sheet of the present invention, its component comprise polyvinyl chloride (PVC), wood powder, mineral filler, lubricant, thermo-stabilizer, linking agent, solubilizing agent and tinting material, it is characterized in that:

The physicals of the polyvinyl chloride in the component (PVC) is: molecular weight is a weight-average molecular weight 14.3 ten thousand～14.5 ten thousand, and water content is lower than 0.5%, meal; Wood powder uses the wood working tankage, and its granularity is 300 orders, 80～85%, 200 orders 15～20%, and water content is 0.01～0.5; Filler is titanium dioxide or lime carbonate, and its granularity is 150 orders～200 orders; Lubricant uses second to hand over the two stearic amides of base, and its physicals is white or buff powder, and relative density is 0.9,130 ℃ ~ 145 ℃ of molten points, perhaps use Ployethylene Wax and AC629-A mixture, wherein the Ployethylene Wax molecular weight is 1500 ~ 2500, and AC629-is an oxidic polyethylene; Thermo-stabilizer uses calcium stearate; Linking agent uses the different monooctyl ester dioctyltin of ethyl thioglycollic acid; Solubilizing agent uses ACR-401; More than the weight percent of each component in material be: polyvinyl chloride is 45%～48%; Wood powder is 38%～40%; Mineral filler is titanium dioxide or lime carbonate, and consumption is 6%～7%; It is 0.8～1% that second is handed over the two stearic amide consumptions of base, and perhaps Ployethylene Wax 0.3～0.5, and AC629 is an ethylene oxide 0.5%～0.8%; Calcium stearate is 0.7%～0.8%; The different monooctyl ester dioctyltin of ethyl thioglycollic acid is 0.9% ~ 1%; ACR-401 is 3%～4%; Tinting material is any.

One of embodiments of the invention are: the weight percent of each component in material is: polyvinyl chloride is that 47% wood powder is 40%; Mineral filler is titanium dioxide or lime carbonate, and consumption is 6.5%; It is 1% that second is handed over the two stearic amide consumptions of base, and perhaps Ployethylene Wax 0.5 and AC629 are ethylene oxide 0.7%; Calcium stearate is 0.8%; The different monooctyl ester dioctyltin of ethyl thioglycollic acid is 1%; ACR-401 is 3%; Tinting material is any.

Two of embodiments of the invention are: the weight percent of each component in material is: polyvinyl chloride is that 48% wood powder is 38%; Mineral filler is titanium dioxide or lime carbonate, and consumption is 6%; It is 1% that second is handed over the two stearic amide consumptions of base, and perhaps Ployethylene Wax 0.45 and AC629 are ethylene oxide 0.8%; Calcium stearate is 0.8%; The different monooctyl ester dioctyltin of ethyl thioglycollic acid is 0.94%; ACR-401 is 3.65%; Surplus is tinting material.According to the plastic wood sheet set of dispense ratio that the present invention proposes, adopt polymkeric substance and wood powder through processing treatment, mixing, granulation, the pellet of different components proportioning is mixed extrusion moulding when the moulding.Component of the present invention is that the contriver proposes on the basis of a large amount of experiments.The plastic wood sheet of making in the scope of technical solution of the present invention has water-fastly, and acid and alkali-resistance is not damaged by worms, long fungi, free of contamination characteristics.Sheet material of the present invention is easy to process, can follow closely, and can bore, and can dig, and can glue, can color oil.Sheet material material of the present invention is even, and smooth surface is smooth, firm, can be according to the various section bars of the different Mold Makings goods identical with timber unity and coherence in writing.There is not timber inherent defective in sheet material of the present invention, as scar joint, be full of cracks warpage, and the spot that easily adds lustre to, malicious spot and rotten etc.Sheet material of the present invention can also reclaim second stage employ.Sheet material of the present invention has been widely used: can make template, wall dunnage, deck panels etc. at building field; Can be intended to door and window in the decoration field, wallboard, floor, furred ceiling, corner line, door socket, baseboard, picture frame and various furniture etc.; Can manufacture carrying backing plate and pallet at packaging field; Can make railway sleeper and motorway insulating board at field of traffic; Can also manufacture open-air tables and chairs, barrier and fence etc.
