聚氯乙烯（PVC）糊樹脂顧名思義是此種樹脂主要以制成糊狀形式來應(yīng)用，人們常用此種糊稱作增塑糊，是未加工狀態(tài)下的聚氯乙烯塑料的一種獨(dú)特液體形式。糊樹脂常由乳液和微懸浮法制得。
聚氯乙烯糊樹脂因粒度微細(xì)，其質(zhì)地像滑石粉，具有不流動性。聚氯乙烯糊樹脂同增塑劑混合后經(jīng)攪拌形成穩(wěn)定的懸浮液，即制成PVC糊料，或稱作PVC增塑糊、PVC溶膠，而且人們正是以這種形式用來加工成終制品。在制糊過程中，根據(jù)不同的制品需要，添加各種填料、稀釋劑、熱穩(wěn)定劑、發(fā)泡劑及光穩(wěn)定劑等。
PVC糊樹脂工業(yè)的發(fā)展，提供了僅經(jīng)加熱就變?yōu)榫勐纫蚁┲破返囊环N新型的液態(tài)材料。該種液態(tài)材料配置方便，性能穩(wěn)定、易控制、使用方便、制品性能優(yōu)良、化學(xué)穩(wěn)定性好，具有一定的機(jī)械強(qiáng)度、易著色等，因此被廣泛應(yīng)用于人造革、搪膠玩具、軟質(zhì)商標(biāo)、墻紙、油漆涂料、發(fā)泡塑膠等的生產(chǎn)。

POLYVINYL CHLORIDE Polyvinyl Chloride (PVC) is a polymer bed by the polymerization of vinyl chloride monomer (VCM) in the presence of peroxide, Azo compound and other initiators, or by the mechanism of Radical polymerization under the b of light and heat. Homopolymer of vinyl chloride and Copolymer of vinyl chloride are called vinyl chloride resins. PVC is a white powder with amorphous structure, the degree of branching is relatively small, the relative density is about 1.4, the glass transition temperature is about 77 ~ 90 °C, the decomb temperature is about 170 °c, the stability to light and heat is poor, above 100 °C or after long-time sunlight exposure, it will decompose and produce, and further automatic catalytic decomb, cause discoloration, physical and mechanical properties also rapidly decline, in the practical application must be added to enhance the stability to heat and light. The polyvinyl chloride is an amorphous polymer with a small shrinkage. Powder should be preheated before processing to remove water, enhance plasticizing effect, prevent bubbles. And PVC easy to decompose, especially in high temperature and steel, copper contact easier to decompose (decomb temperature 200 degrees) . Molding temperature range is small, must strictly control the material temperature. Use of screw injection machine and through the nozzle, the aperture should be large, in order to prevent dead-end material. Mold pouring system should be large, gate section should be large, mold should be cooled, mold temperature 30-60 degrees, material temperature 160-190. Under the glass transition temperature (TG, 80 °C) , the polyvinyl chloride is in the glass state; at the TG → viscous flow temperature (TF, about 160 °C) , it is highly elastic and rubbery, and has plasticity; at the TF → thermal decomb temperature (Td) , it is viscous flow state, the higher the temperature, the easier the flow is. When the temperature exceeds TD, a large amount of HCL is decomposed out of PVC, and the material loses its chemical stability and physical properties. Therefore, Td is the upper limit of processing temperature. Due to the large intermolecular force of polyethylene, TF is very high, even close to the decomb temperature, so plasticizers need to be added to reduce TF. On the other hand also need to add stabilizers, so as to improve the TD of PVC, in order to process molding. Vinyl chloride polymer. PVC. The polyvinyl chloride is the second largest variety of plastic, after polyethylene. Glass transition temperature 80 ~ 85 °C, density 1.35 ~ 1.45 G/CM, use temperature-15 ~ 60 °C. PVC has excellent acid and alkali resistance, wear resistance, fire resistance and insulation properties, and most of the plasticizers mixing well, so can significantly change the material's mechanical properties. Good processing perbance, low price, but to light, thermal stability, 100 °C above or under light rapidly decline in perbance. PVC materials are widely used, mainly used in the production of: Pravin PVC card; PVC oem; Pvc Iron Wire; PVC curtain; PVC Coated Welded Mesh; PVC Foam Board, PVC ceiling, PVC water pipe, PVC skirting line and so on as well as threading pipe, cable insulation, plastic doors and bs, plastic bags, etc. . PVC products can be seen everywhere in our daily life. PVC is used to make a variety of imitation leather, used in luggage, sporting goods, such as basketball, football and football. The utility model can also be used for making belts for unibs and special protective equipment. PVC material is widely used, and has good processing perbance, low manufacturing cost, corrosion resistance, insulation and other good characteristics.
