Therefore, we will study it in

5、 the Article the status quo, progress in respect of Applications to give a brief overview. PVC paste resin (PPVC) is a PVC resin in a large class, and suspension resins are high compared to dispersion of powder, pArticle size range is generally 0.1 2.0 m (suspension resin particle size distribution

6、is generally 20 200 m). PVC paste resin is a law in Germany in 1931, this (IG Farben) plant began to study, and in 1937 achieved industrial production. PVC paste resin is currently the world's total production capacity of about 2 million t / a. Among them, Western Europe is the largest manufactu

7、rer of PVC paste resin, the output of the region's largest Western European countries of PVC paste resin production capacity has reached 70 million to 750 thousand t / a. In developed countries the vast majority of PVC paste resin production enterprises using ethylene France route, and a larger

8、scale. From the production point of view, has developed seed emulsion polymerization method, emulsion poly-continuous method, no seed emulsion polymerization, micro-suspension polymerization, seeds, micro-suspension, emulsion micro-mixing method, etc.; PVC paste resin industry in China start in the

9、50's. Domestic PVC paste resin manufacturers nearly 20, with a total production capacity of about l7.65 million t / a, accounting for a total production capacity of PVC resin, 9.6%. Production process in order to seed emulsion-based, the other also-continuous emulsion, micro-suspension law, the

10、vast majority of raw material for the calcium carbide route. Although China has introduced foreign seven brands the company's 35 production technology of PVC paste resin, basically encompass the contemporary world's leading PVC paste resin production methods, but with the world's advance

11、d level, there are still some gaps. Their preparation methods are mainly the following: 1. Emulsion Emulsion formulations are mainly VCM, water, water-soluble initiator and emulsifier. Polymerization of the mixing requirements are very strict, triggering role is carried out in aqueous solution, comm

12、only used initiator is too water-soluble sulfate. Under normal circumstances, the latex emulsion particle size to be smaller than 0.2 m, in order to achieve the purpose of increasing latex particle size was developed seed emulsion polymerization, so that latex particle size was increased to about 1.

13、0 m. In the emulsion polymerization, if there is a high polymer latex has been generated there, the control ratio of materials and conditions, in principle, VCM has been generated only in the latex polymer particles rather than the formation of new particles; it has generated a high polymer latex li

14、ke seeds, so called "seed emulsion polymerization." However, only a reasonable size is not enough, you must have the appropriate particle size distribution, to get good performance of the PVC paste resin. Emulsion polymerization is very important in the emulsifier, the initiator us

15、ed determines the number of particle number, and the final latex particle size played a major role. Particularly during seed is generated when the high trigger rate and low concentration of emulsifier production, can narrow size distribution of latex particles. 2. Micro-suspension method Micro-suspe

16、nsion polymerization system was PVC paste resin is a relatively new way, as early as the mid-20th century, 60 have been industrialized. The process is: first part of the VCM (5%) by mechanical homogenization of the method for producing a stable emulsion (particle size of about 1.0 m), and then proce

17、ed to aggregate (must use oil-soluble initiator). Produced by this method the mobility of PVC paste resin excellent emulsifier with less resin thermal stability and water resistance are improved. The production process is required to pay special attention to the following factors: selection of a sui

18、table emulsifier and particle conditioner system; polymerization system components homogenization; stirring speed; water and the appropriate ratio of monomers. 3. Mixing method PVC paste resin production process mixing method is mainly set emulsion and micro-suspension polymerization in one, through

19、out the reaction process to join through the emulsion after the seeds and other emulsifier, initiator, various auxiliaries and join VCM response. Hybrid method with the C16 and C18 straight-chain alcohols mixed with sodium dodecyl sulfate, or the composition of lauric acid amine emulsifier to form m

20、icro-emulsion polymerization carried out mainly in the micro-droplets. After the seed emulsion polymerization by adding a bimodal distribution of the entire particle size. PVC paste resin has been widely used in artificial leather, impregnated gloves, wallpaper, adhesives, automotive sealing materia

21、l, steel coatings, paints, footwear and other advanced Applications. It is estimated that in 2000 the world's total consumption of PVC paste resin market, about 1.66 million t / a. In China, PVC materials, there are two good application results: 1, Plastic drop cotton products. This process made

22、 of cotton through the Plastic drop plastic products in China are new technology products, it is based on a variety of knitted fabric cotton and various blends as raw materials in its surface, drops of white or color PVC small particles, these small particles into the hemispherical surface of the cl

This cotton fabric has excellent wear-resistant plastic, non-slip, heat insulation, insulation and perspire all over the performance of gloves made of a more popular trend in today's world, all kinds of knitting, nyl

24、on, canvas and work gloves generation product. 2, used in the automotive industry. Automotive Plastics has entered a higher intensity, quality, the second generation of lighter materials. The use of PVC paste resin plasticized paste prepared by the slush, rotation molding, dip molding and other proc

26、the feel and appearance of a sense of natural harmony. As the PVC paste resin molding processing and suspension PVC resin processing equipment compared to low-cost, simple and inexpensive molds can be made into special shapes, foam easy, the number of products less heat and can be a small amount of

27、varieties in production, etc., so the current plastics processing industry optimistic about the situation. China's rapid development over the past few years, the industry's annual capacity is growing rapidly; but in rapid development, a number of issues must also be emphasis on early and res
