Abstract
The utility model relates to a five-layer co-extrusion building material membrane which comprises an upper surface layer, a second upper layer, a central layer, a second lower layer and a lower surface layer which are all formed through co-extrusion and two-way stretch, wherein the upper surface layer is a corona layer, the second upper layer is a whitening layer, the central layer is a calcium carbonate composite foam layer and a whitening layer, the second lower layer is a whitening layer and the lower surface layer is a heat-seal layer. The five-layer co-extrusion building material membrane simplifies processing technology and reduces manufacturing cost. The five-layer co-extrusion building material membrane has the advantages of being high in shading rate, firm in compositing, good in anti-aging effect of surfaces, light in weight, free from polluting environment and the like. After being used, the building material membrane can be recycled to make other plastic products. A large amount of oil resources are saved, and usage cost of users is reduced.
Description
Technical field
The utility model belongs to packaging material, particularly relates to a kind of five-layer co-squeezing building materials film.
Background technology
In recent years, heat preservation energy-saving has become the hot issue of people's research.Can reduce indoor heat loss at building masonry wall and roof laying one layer of heat preservation material, reach the purpose of heat preservation energy-saving.At present, being widely used in the hard polyurethane foam board of building roof heat insulating material, is the decorative panel shell of being manufactured shaping by the PVC material, injects polyurethane foams and consist of in the decorative panel shell.The deficiency of traditional PVC product is: thick and heavy, not environmental protection, not attractive in appearance, can't satisfy the demand of high-grade building; And manually build compound tense take a lot of work, time-consuming, affect efficiency of construction.
Summary of the invention
But the utility model provides a kind of one-shot forming for solving the technical problem that exists in the known technology, reduces manufacturing cost; Shading rate is good, combined strength bination is high, surperficial antiageing effect is good, the five-layer co-squeezing building materials film of light weight, non-environmental-pollution.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: five-layer co-squeezing building materials film, comprise upper epidermis through the coextrusion biaxial tension, last time top layer, sandwich layer, next top layer, lower top layer five-layer structure, the layered arrangement structure of described five-layer co-squeezing building materials film is followed successively by:
Described upper epidermis is the corona layer, last time the top layer for brightening layer, sandwich layer is the compound of calcium carbonate foaming layer and brightens layer, next top layer is for brightening layer, lower top layer is hot sealing layer;
The utility model can also adopt following technical scheme:
Described upper epidermis, last time, the thickness on top layer, next top layer and lower top layer was 3～5% of building materials film gross thickness respectively.
Advantage and the good effect that the utlity model has are: because top layer of the present utility model, inferior top layer and sandwich layer need not the techniques such as compound or film all by the coextrusion one-shot forming again in manufacturing process, simplified processing technology; The building materials film that processes has the reduction manufacturing cost, and alternative tradition is thick and heavy and environment-friendly PVC product not, wins widely favorable comment and market with advantages such as attractive in appearance, environmental protection, low cost, thin thickness.Be mainly used in and aluminum film compounded building film for gloss white and high reflecting metal face, the effect of thermal insulation, control condensation and dewfall is arranged; With kraft compounded be the polypropylene veneer of semi-glossy white, can keep pliable and tough, without stratification.Make its client improve profit, adapt to special application field, also can increase the service life, reduce client's use cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, upper epidermis; 2, last time the top layer; 3, sandwich layer; 4, next top layer; 5, lower top layer.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of five-layer co-squeezing building materials film comprises upper epidermis 1 through the coextrusion biaxial tension, last time top layer 2, sandwich layer 3, next top layer 4 and lower top layer 5 five-layer structures.The layered arrangement structure of described building materials film is followed successively by: described upper epidermis 1 corona layer, described last time, top layer 2 was for brightening layer, described sandwich layer 3 adds an amount of compound of calcium carbonate, brightens the masterbatch formation for the HOPP resin, and described next top layer 4 is for brightening layer, and described lower top layer 5 is hot sealing layer.Described upper epidermis 1 and last time top layer 2 material be that masterbatch is brightened in 100% special use; Sandwich layer 3 brightens the sandwich layer that masterbatch consists of for the HOPP resin adds an amount of compound of calcium carbonate, special use; Next time, the material on top layer 4 was that masterbatch is brightened in 100% special use; The material on lower top layer 5 is that the COPP resin adds an amount of anti-stick masterbatch that connects.In the present embodiment, described upper epidermis, last time, the thickness on top layer, next top layer and lower top layer was 3～5% of building materials film gross thickness respectively.
