Novel foaming wood plastic template in use for architecture and production technique thereof
Technical field
The invention belongs to building template manufacturing technology field, be specifically related to a kind of Novel foaming wood plastic template in use for architecture and production technique thereof.
Background technology
Plastics and steel, timber, cement are referred to as four large material of construction.The production of building plastic product and application energy consumption are all far below other materials, and plastic mould is a kind of energy-saving environmental protection product, therefore, apply plastic mould and be economize on resources, the important measures of energy efficient, " to mould Dai Mu ", " to mould Dai Gang ".Apply plastic mould and have vast potential for future development, adopting plastic mould should be the inevitable development direction of industry.
In recent years, along with country advocate energetically exploitation energy-conservation, low consumption product, and the development of China's plastics industry and the improvement in performance of plastics composite, various novel plastic templates are also being continually developed and are being born.Although the plastic mould history of existing 30 years, so far aspect product technology still without industry standard, manufacturing enterprise's major part does not have company standard.In recent years, apply more and morely along with plastic mould in building operation, market outlook are become better and better, and many plastics-production enterprise enters into the ranks of producing plastic mould.In construction work and bridge construction, also widely applied at present, obtained some effects.But for various reasons, still do not produce real foaming building template.
Summary of the invention
The object of the present invention is to provide a kind of Novel foaming wood plastic template in use for architecture and production technique thereof, accomplish real foaming, outer real skinning, skinning thickness reaches 1 millimeter, and hardness is strong, and toughness and nail-holding ability exceed wooden form.
Novel foaming wood plastic template in use for architecture of the present invention, is made up of the material of following weight fraction: polyvinyl chloride (PVC) RESINS 60-80 part; Activation wood powder 10-15 part; Activation fine particle calcium carbonate 20-40 part; Building template reclaimed materials 30-50 part; Lead salt one package stabilizer 2.8-3.2 part; Foaming control agent 10-12 part; AC whipping agent 0.2-0.4 part; NC whipping agent 0.6-0.9 part; Stearic acid 0.2-0.3 part; Oxidized polyethlene wax 0.3-0.5 part, internal lubricant G60 0.5-0.7 part; 0.3 part of external lubricant OA3; Toughner poe5 part, wherein wood powder and fine particle calcium carbonate need to carry out activation treatment before using.
Described activation treatment refers to: 100 parts of materials that need to activate are joined to 3 parts of stearic acid and be added to the mixed pot of 110-130 ℃ of heat, be uniformly mixed 20~30 minutes, the concrete time is controlled according to the warm speed of self-friction life.By preventing thickener phenomenon to the activation treatment of wood powder, calcium powder.
The production craft step of Novel foaming wood plastic template in use for architecture of the present invention is as follows:
(1) raw material is joined in the mixed pot of heat and carry out batch mixing, heating;
(2) send into main frame after being cooled to 40-45 ℃ and plastify foaming under 180-220 ℃ of condition, by die lip water route, product is carried out to open water cooling skinning;
(3) regulating shaping platform and cooling-water machine temperature to be 15-22 ℃ shapes with cooling to extruded stock;
(4) under the traction of tractor to sizing after product carry out longitudinally, transverse cutting, the tabular Novel foaming wood plastic template in use for architecture of the standard that obtains.
Described batch mixing refers to that polyvinyl chloride (PVC) RESINS, wood powder, fine particle calcium carbonate, building template reclaimed materials are joined to the mixed pot of heat is heated to 70~90 ℃, then lead salt one package stabilizer, foaming control agent, AC whipping agent, NC whipping agent, stearic acid, oxidized polyethlene wax, internal lubricant G60, external lubricant OA3, toughner poe are added in the mixed pot of heat, mix post-heating to 110-130 ℃.
Pulling speed, rate of feeding and the main frame speed of described tractor are synchronous.
Compared with prior art, the invention has the beneficial effects as follows:
(1), practicality: can saw, can follow closely, can dig, can glue, can be processed into any geometrical shape, possess all installation capabilities of solid wood, and quality be light, be easier to the processing of bamboo and wood template.
(2), functional: waterproof, fire prevention, Anti-moth-eating, alkaline-resisting, anticorrosion, sound insulation, have good stability weathering resistance, any waterproof that it goes without doing, preventing coating protection, can arbitrarily put in any environment.
(3), saving property: do not absorb water after this product deposit concrete, surfacing, saves secondary plastering engineering, and plate face need not be brushed releasing agent, and stripping result is good.Easy for installation, saving working hour, tailing and material itself be recoverable all.
(4), the feature of environmental protection: substitute punching block, bamboo mould, wooden model.Protection is ecological, concern is healthy, builds and fit up pollution-free.
