Background technology
Polyvinyl chloride（Abbreviation PVC）It is one of macromolecular material for being most widely used, due to it have it is nontoxic, transparent, be easily worked shaping, especially post forming air-tightness, colourability are good, there is preferable physical property etc., each side can be met as the requirement of packaging material, be widely used in packaging field.But PVC toughness is poor, category fragile material, its melt viscosity is high simultaneously, and heating is easily decomposed, processing temperature is close to decomposition temperature, therefore the product that obtain preferable transparent shock-resistant hard PVC is modified, it is necessary to add such as second, third component processing aid of impact modifier, stabilizer, lubricant, toner to it.
In transparent shock-resistant hard PVC material, anti-impact modifier is large usage quantity in processing, is also a kind of most important auxiliary agent, is added in blend as the second component.PVC transparent impact modifier must possess two fundamental characteristics, and one is the impact strength that can significantly improve PVC hard product, and two is the optical property for not influenceing product.Impact modifier is mainly some copolymer resinses or modified resin both at home and abroad at present, and conventional kind has haloflex (CPE), ethylene-vinyl acetate copolymer (EVA), polyacrylate (ACR), MBS ternary graft copolymers (MBS) and acrylonitrile-butadiene-styrene copolymer (ABS).The translucency of MBS and ACR is good in these materials, and the compatibility with PVC is good, usually as PVC transparent impact modifier.MBS and ACR belong to rubber elastomer class impact modifier, all there is typical nucleocapsid structure, it is made up of the soft core of rubber components and the duricrust of plastics phase, soft core is generally polybutadiene or polyacrylate, duricrust is generally styrene and polymethyl methacrylate rigid polymer.In processing mixing process, soft core rubber is distributed in PVC continuous phases with particle state, crust layer plays interface bonding agent between PVC and rubber particles and is formed homogeneously with PVC, present " sea-island structure ", the presence of " sea-island structure ", illustrate that MBS and ACR classes impact modifier can not be fully compatible with resin matrix, form two phase structure.
In transparent shock-resistant hard PVC blend, because the presence of two phase structure will ensure the transparency of material, one is the wavelength of the particle diameter less than light wave of dispersed phase impact modifier micelle, reduces the loss of luminous flux；Two are available with appropriate auxiliary agent improves impact modifier and resin-based compatibility, eliminates or reduce boundary difference, makes two-phase refractive index close or relatively, so as to keep its light transmittance.
CN201310204620 patent documents disclose a kind of transparent PVC pellet and its production method, and the pellet is made up of the weight portion of polyvinyl chloride base-material 100, in-lubricant 1-2 weight portions, heat stabilizer 1.0-1.5 weight portions, plasticizer DOP 1-40 weight portions, impact modifier 3-10 weight portions, processing aid ACR1-2 weight portions, external lubricant 0.2-0.8 weight portions and pigment.The transparent PVC pellet produced using the method has the certain transparency, good workability, weatherability, stability and mechanical property, extrusion can be met, prolong the moulding process requirements such as pressure, but the product of the transparent shock-resistant hard PVC of high-quality cannot be met to high transparency, the requirement of high-impact.

The technical solution adopted for the present invention to solve the technical problems is：A kind of transparent shock-resistant hard PVC pellet composition and preparation method, it is characterized in that with vinyl chloride-vinyl acetate-butyl acrylate terpolymer resin as bridging agent, other modifying agent mixing granulations are coordinated to form, the composition includes following components, and is with the weight of other components on the basis of every 100 weight portion PVC：Polyvinyl chloride 100, impact modifier 8-15, bridging agent 2-4, heat stabilizer 1-3, plasticizer 2-3, lubricant 0.3-0.8, toner 0.1-0.3.
Vinyl chloride-vinyl acetate-butyl acrylate terpolymer resin that the present invention is used is added dropwise technique productions using suspension method co-continuous, butyl acrylate, vinyl chloride, the reactivity ratio of vinylacetate differ larger, the autohemagglutination speed of butyl acrylate is far longer than copolymerization rate, production technology is added dropwise using co-continuous can effectively control polymerization rate, keep the stationarity of reaction pressure, copolymer each component is polymerized in order in polymerization process, realize regular and each component the uniformity of product particle.The resin of the method production is applied to PVC blending processing, and acrylate is conducive to improving the compatibility of impact modifier and polyvinyl chloride resin in copolymer, beneficial to eliminating or reducing boundary difference, so as to maintain the raising of light transmittance.The internal plasticization of vinylacetate, can well solve the problems, such as the migration of plasticizer of PVC product during use, promote plasticizing of the blend each component in mixing, improve the jelly grade of blend, and then improve the glossiness and light transmittance of product.
The PVC produces resin using suspension method, substance law, and one or two are combined, and the degree of polymerization is 750-850.Consider the processing and forming technology performance of rigid plastics and its physical and mechanical properties of product, be about the resin of 750-850 from the degree of polymerization, work in-process resin can fusion plastification in the short period of time, and reach uniform, stability, the transparency of product is also higher.
For MBS, ACR, one or two are combined the impact modifier, particle size range 50-200nm of impact modifier micelle.The particle size range of impact modifier micelle is controlled in 50-200nm, ensure that the wavelength of the particle diameter less than light wave of dispersed phase impact modifier micelle, be conducive to smooth propagation of the visible ray in transparent shock-resistant hard PVC material, the loss of luminous flux is avoided or reduces, beneficial to the transparent raising of transparent shock-resistant hard PVC material.
The bridging agent is vinyl chloride-vinyl acetate-butyl acrylate terpolymer resin that suspension method co-continuous are added dropwise technique productions, and the degree of polymerization is 750-850, vinyl acetate content 3-5%, butyl acrylate content 3-5%.The same or analogous each component of the degree of polymerization, processing mixing process is conducive to synchronously to plastify, ensure that especially thin slice or membranaceous product are produced product without flow liner, content is relatively low in the copolymer for vinylacetate and butyl acrylate, be conducive to keeping the distinctive rigidity characteris of PVC, meet the rigid requirements of hard PVC material.
The heat stabilizer be organotin, organic antimony stabilizer one or two be combined；The plasticizer be dioctyl phthalate, epoxidized soybean oil one or two be combined；The lubricant is stearic acid；The toner be ultramarine, transparent blue, violet one or more.Organotin, organic antimony stabilizer, heat endurance is good not to be influenceed on the transparency, dioctyl phthalate, epoxidized soybean oil be a kind of or the compound plasticizing that may advantageously facilitate between blend each component, stearic acid is conducive to improving the mobility of resin, and toner is conducive to removing the initial coloration in process.
