Abstract
The production process of high transparency polycarbonate film and sheet includes the following steps: 1. drying the material in a drier; 2. homogenizing the material and extruding to form in a gas-liquid combining gradient cooling process; 3. winding; 4. coating film; and 5. edge cutting and packing. The present invention has the advantages of high transparency of the produced polycarbonate film and sheet, high yield rate and high product quality.
Description
Technical field
The present invention relates to the chemical products production field.
Background technology
At present, a kind of plastic polycarbonate film with shield electromagnetic interference/Radio frequency interference (EMI/RFI) characteristic is succeeded in developing by the Bayer Plastics Company of U.S.'s Regensburg.Polycarbonate film has good comprehensive performances, general thin is a water white transparency, light transmittance is more than 90%, the very suitable optical material of doing, PC is the electrical property excellence not only, and have higher draw tensile strength and a rigidity, resistance to impact also is that the water absorption rate and the product molding shrinkage factor of PC film higher in the thermoplastic is low, creep-resistant property is good, thereby under different temperature, damp condition the dimensionally stable of goods, particularly its cold resistance and hear resistance are very excellent be fit to make precision element, can long-term work in the scope of 100～130 ℃ of broads.Aspect electronics industry, be mainly used in and make thin-film capacitor, electroacoustic component and be used as the electrical apparatus insulation material.Aspect scientific research, can be used as solid vestige detecting material, be applied to the study of high energy physics field, as predict an earthquake, monitoring of environmental, mine locating etc., the microporous membrane of making after treatment, be good molecular screen material, can be used as microbe research and the novel filter material that is used for the aspects such as production of brewing industry, ultra-pure water.Since polycarbonate film transparent nontoxic, tasteless, do not have and to smell, have good fragrance protectiveness, can be used for the packing of food and medicine.Suitability for secondary processing such as its printing and evaporation metal, vacuum suction moulding are also very good, can process and be copied into various beautiful decorations, or make various composite articles with other material.In addition, the heat endurance of PC film, lower temperature resistance, moisture impermeability and good weatherability at aspects such as the future of agriculture greenhouse and solar energy utilizations, also have very wide prospect.Though China is a plastic sheeting and sheet production and consumption big country, product rests on the films such as PVC, PE, PP, PET mostly, still is a blank to the exploitation of the polycarbonate membrane widelyd popularize in the world at present, abroad to its production technology from unexposed.
Summary of the invention
Purpose of the present invention be exactly at China also do not produce polycarbonate membrane manufacturer deficiency and a kind of high transparency polycarbonate film and sheet material production technology are provided, its production technology is: a, raw material drying: raw material drying device is fully dry; B, homogenizing extrusion molding: adopt the material homogenizer extrusion molding after gas, liquid coupling gradient process for cooling will plastify; C, rolling; D, multiple film; E, the packing of cutting edge.The invention has the advantages that the polycarbonate membrane transparency height of production, raw material output capacity height, quality is equal to the import polycarbonate membrane, can replace the import polycarbonate membrane fully, fills up the blank of domestic production high transparency polycarbonate film.
The specific embodiment: a, raw material drying: raw material drying device is fully dry; B, homogenizing extrusion molding: adopt the material homogenizer extrusion molding after gas, liquid coupling gradient process for cooling will plastify; C, rolling; D, multiple film; E, the packing of cutting edge.
