Abstract
The invention relates to the technical field of synthetic paper production, which comprises a surface layer, an inner layer and a middle layer, wherein the surface layer and the inner layer adopt a master batch special for synthetic paper, and the middle layer adopts a raw material which is prepared by processing and contains high-density polyethylene, metallocene polyolefin and low-density polyethylene. The surface of the invention has better papering property, the physical and mechanical properties of the invention are greatly higher than those of the traditional fiber paper, the invention has the characteristics of high strength, good folding resistance, stable size, smooth surface, water resistance, moisture resistance, mildew resistance, moth resistance, acid and alkali resistance and the like, and the invention has the advantages of convenient processing, low cost and no pollution.
Description
Technical field
The present invention relates to the synthetic paper production technical field.
Background technology
Replace at present the paper purposes on the domestic and international market, the synthetic paper that is applied to printing industry has multiple, but along with the continuous development of society, people require also more and more higher to the demand of synthetic paper, a kind of PP synthetic paper need be used ink special during printing, and common ink is inapplicable; Another kind of non-woven paper, its complex manufacturing, the cost height, the price height, its scope of application is restricted.
Technical scheme
The purpose of this invention is to provide a kind of above-mentioned defective that overcomes, can improve the quality of products, applied widely, simple novel multi-layer synthetic paper of technology and production technology thereof.
The present invention comprises superficial layer, internal layer and intermediate layer, and superficial layer, internal layer adopt dedicated parent material for synthetic paper, and the intermediate layer is adopted and comprised high density polyethylene, metallocene-polyolefin and low density polyethylene (LDPE) combination and the raw material through being processed into.
Raw material each ingredients constitute total amount percentage in intermediate layer is: high density polyethylene accounts for 50～70%, metallocene-polyolefin accounts for 22～40%, low density polyethylene (LDPE) accounts for 8～10%; The dedicated parent material for synthetic paper each component accounts for total amount percentage: CaCO
3Account for 30～45%, TIO
28～13%, HDPE accounts for 30～40%, LDPE accounts for 8～13%, and other composition is coupling agent and dispersant, antistatic agent.
Production technology of the present invention is, adopt masterbatch the synthetic paper surface layer, adopt the intermediate layer and the synthetic paper internal layer of mixed material to extrude respectively for three layers, form three-layer co-extruded synthetic paper structure through triple extrusion die head again, through blown film, the drawn shaping is to finished product again.
The present invention is internal layer and superficial layer owing to having adopted by dedicated parent material for synthetic paper, again because new proportioning has been adopted in the intermediate layer, behind blown film and corona, the paper characteristic on surface is better, improved product quality, and physical and mechanical properties is much higher than traditional fibre paper, has the intensity height, folding resistance can be good, dimensionally stable, smooth surface, water-fast protection against the tide, mildew-resistant, mothproof, characteristics such as acid and alkali-resistance can be widely used in 1, printing, as senior chromaticity printing, ancient books, product sample, map, sea chart, textbook etc.2, the extraordinary paper of using is as area of computer aided paper, namecard, disposable tableware, dixie cup, advertisement, the dial of replacement metal, false proof bank note etc.3, packaging material and tourism supplies are as handbag, packaging bag, paper cap, paper fan, umbrella, playing card etc.Technology uniqueness of the present invention, easy to process, cost is low and pollution-free.
Specific embodiments
The present invention includes superficial layer, internal layer and intermediate layer, superficial layer and internal layer adopt " dedicated parent material for synthetic paper " of patent applied for, and this masterbatch is by the CaO that accounts for total amount 35～45%
3, 8～13% TIO
2, 30～40% HDPE, 8～13% LDPE and auxiliary agent, and the back that processes from strand is stand-by, the intermediate layer adopts the high density polyethylene account for total amount percentage 50～70%, 22～40% metallocene-polyolefin, 8～13% low density polyethylene (LDPE) through mixing, plasticate the raw material that processes and stand-by, after superficial layer masterbatch, intermediate layer and internal layer raw material extruded respectively by extruder separately, be total to the agent die head through three layers again, through blown film, drawn shaping again, corona treatment is cut and is promptly made the novel multi-layer synthetic paper.
Temperature is set at normal temperature between three layers of common agent die head and the three-layer co-extruded blown film, and 7 districts are respectively 175 ℃, and 180 ℃, 185 ℃, 190 ℃, 185 ℃, 185 ℃, 175 ℃.Stretching shaping temperature is 100～120 ℃, extruder, corona treatment, cuts the employing common process.
Claims (3)
1, a kind of novel multi-layer synthetic paper, it is characterized in that, it comprises superficial layer, internal layer and intermediate layer, and superficial layer, internal layer adopt dedicated parent material for synthetic paper, and the intermediate layer is adopted and comprised high density polyethylene (HDPE), metallocene-polyolefin and low density polyethylene (LDPE) combination and the raw material through being processed into.
According to the described novel multi-layer synthetic paper of claim 1, it is characterized in that 2, raw material each ingredients constitute total amount percentage in intermediate layer is: high density polyethylene accounts for 50～70%, metallocene-polyolefin accounts for 22～40%, low density polyethylene (LDPE) accounts for 8～10%; The dedicated parent material for synthetic paper each component accounts for total amount percentage: CaCO
3Account for 30～45%, TIO
2Account for 8～13%, HDPE accounts for 30～40%, LDPE accounts for 8～13%, other composition is coupling agent and dispersant, antistatic agent.
3, a kind of production technology of making the novel multi-layer synthetic paper, it is characterized in that, adopt the synthetic paper surface layer of masterbatch, the intermediate layer of employing mixed material and the internal layer of synthetic paper to extrude respectively for three layers, form three-layer co-extruded synthetic paper structure through triple extrusion die head again, through blown film, the drawn shaping is to finished product again.
