Description

A kind of pvc billboard
Technical field
The present invention relates to Wood-plastic material technical field, particularly relate to a kind of pvc billboard.
Background technology
China is the country that a timber does not enrich, and underproducely causes the demand that can not meet market.Enhancing along with environmental consciousness and the protection to trees, wood plastic composite swarms into the visual field of people gradually, and Wood-plastic material is that one wood powder, xylon or other vegetable fibre fill thermoplastic polymer composite material, has the advantage of timber and plastics concurrently.According to the kind of thermoplastics used, can be divided into that PVC foam wood/plastic, ABS foaming wood-plastic, PS foaming wood-plastic, PE wood are moulded, PP wood is moulded, Wood-plastic material is because of advantages such as its environmental protection, shaping efficiency are high, the friendly of waterproof, good weatherability, environment, and development in recent years more and more sooner and be applied in each field widely.Although wood plastic composite has a good application prospect, due to more crisp, low impact property, there is higher density compared with natural timber and cause it to be restricted in application.In Wood-plastic material formula; add whipping agent and can prepare foaming wood-plastic goods with abscess; foaming wood-plastic goods are except possessing the feature of traditional wood plastic product; also there is the superperformances such as light weight, heat insulation, noise reduction; but mould formula carry out foaming as whipping agent directly added wood; wood-plastic products often can be uneven because of whipping agent dispersion, causes the problems such as cell size is uneven, product processes is unstable, greatly affect the application performance of goods.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of pvc billboard.
The present invention is achieved by the following technical solutions:

Described a kind of pvc billboard, be made up of following concrete step:
(1) activated Calcium carbonate, linolic acid and ripe rubber powder are mixed, add silane coupling agent kh570 grinding distribution and evenly obtain mixed powder, again polyethylene wax is heated to melting, add Antioxidant DLTP, calcium stearate stirs, be coated on mixed powder surface, made particle for subsequent use;
(2) by the wood powder of granularity between 20-60 order and peanut hull meal heat treated in the temperature range of 190-230 ° of C, by moisture controlled below 3%, being added to by dried mixed powder has in the container of stirring rod, by butyl acrylate, benzoyl peroxide, N, accelerine mixes and is added in mixed powder, control temperature is at 85-90 ° of C, and polyreaction 1-1.5h makes it homogenization, for subsequent use after cooling;
(3) polyvinyl chloride and chlorinatedpolyethylene are placed in the heating of acceleration mixing machine to mix, reduce temperature to the product adding step (1) during 110-115 ° of C and prepare, continue mixing and stirring, AC whipping agent is added and cell modifiers ACR530 is mixed to evenly when adjusting the temperature to 60-65 ° of C, add modification powder stirring prepared by step (2) more even, temperature is controlled stop when 40-45 ° of C stirring to be dry blend;
(4) dry blend step (3) obtained is sent in forcing machine, wherein expressing technique is: district's temperature is 160-165 ° of C, two district's temperature are 175-185 ° of C, three district's temperature are 195-200 ° of C, four district's temperature are 190-195 ° of C, head temperature is 180-185 ° of C, and rotor speed is 35-40r/pm, and extrusion moulding can obtain wood plastic composite.
Advantage of the present invention is: the present invention adopts lubricant to carry out coated to blending ingredients, polyvinyl chloride is made to add minimizing generation in man-hour heat of friction, improve the stability of product and qualitative, and adopt calcium stearate to replace Pb stabilizer, can not only absorbing hydrogen chloride, add and play auxiliary stable effect man-hour, complexing can also be produced with polyvinyl chloride, produce the effect of lubrication, wood powder is also carried out dip treating by the present invention, solve vegetable fibre and pvc resin boundary surface compatibility problem, modified wood powder and resin boundary surface wettability, interfacial adhesion effect is better, improve the physical strength of matrix material, the activated Calcium carbonate added, linolic acid and ripe rubber powder can the intensity of strongthener, thermal denaturation resistant and the cohesiveness improved to each other, pvc billboard prepared by the present invention has the outward appearance of timber, higher than plastics hardness, rigidity is strong, antiacid alkali, anti-aging, ultra-violet resistance is good, long service life, be worthy to be popularized.
