Abstract
A PVC (polyvinyl chloride) scrap composite co-extruded foamed building template is composed of an upper hard surface layer, a lower hard surface layer and a middle foamed layer. The middle foamed layer is PVC waste plastic, and the upper hard surface layer and the lower hard surface layer are PVC resin and are covered on the upper and lower surfaces of the middle foamed layer. The PVC scrap composite co-extruded foamed building template is a building template in a three-layer structure of 'surface layer-core layer-surface layer', and the template core layer is the micro-foamed layer, so that product rigidity is improved and product cost is lowered; the surface layers are the hard PVC resin layers which can function in wear resistance, impact resistance, scratch resistance and the like; and the PVC scrap composite co-extruded foamed building template is excellent in physical and mechanical performances, waterproof, moistureproof, low in water absorbency, light in product deadweight, good in processability, nailable, planable, sawable, drillable, smooth in surface, free of demolding agent and effective in demolding.
Description
Technical field
The utility model relates to a kind of PVC waste material composite co-extruding foaming construction formwork.
Background technology
China's timber resources is poor, and in order to protect limited timber resources, timber conservation becomes inexorable trend with substituting.Use maximum Wood construction formworks in construction work, serious because of loss, reuse number of times few, need to consume a large amount of timber resources.The lumber market imbalance between supply and demand has become the outstanding problem of restriction template industry development.And waste or used plastics increasingly sharpens because dealing with " white pollution " that cause improperly, have a strong impact on the mankind's living environment, rationally utilize waste and scrap exploitation high value added product, realize the recycling of waste or used plastics, to realizing resource regeneration and recycling economy, huge meaning is arranged.
Summary of the invention
The purpose of this utility model just is to provide a kind of life cycle length, smooth surface, waterproof, protection against the tide, wear-resisting, shock proof PVC waste material composite co-extruding foaming construction formwork.
PVC waste material composite co-extruding of the present utility model foaming construction formwork is made of upper hard top layer, lower hard top layer and middle foaming layer, and middle foaming layer is the PVC waste or used plastics, and foaming layer density is 0.5～0.6g/cm
3, upper hard top layer and lower hard top layer are polyvinyl chloride resin, both cover the middle foaming layer upper and lower surface.
PVC waste material composite co-extruding of the present utility model foaming construction formwork is the construction formwork of " top layer-sandwich layer-top layer " three layer construction, and the template sandwich layer is little foaming layer, and the waste PVC plastics that all use have namely increased the rigidity of product, have reduced again the cost of product; The top layer is the hard PVC resin layer, can play the effects such as wear-resisting, shock resistance, scratch; It also has excellent physical and mechanical property simultaneously, waterproof, protection against the tide, water absorption rate are low, the problems such as perishable after the suction of wooden template product, expansion, distortion have fundamentally been solved, in addition, product is from heavy and light, and workability is good, can follow closely, can dig, can saw, can bore, smooth surface need not release agent, and stripping result is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of PVC waste material composite co-extruding foaming construction formwork, consisted of by upper hard top layer 1, lower hard top layer 3 and middle foaming layer 2, middle foaming layer 2 is the PVC waste or used plastics, and upper hard top layer 1 and lower hard top layer 3 are polyvinyl chloride resin, and both cover middle foaming layer 2 upper and lower surfaces.
