Abstract
The invention discloses a formula of a transparent weather-resisting PVC (Polyvinyl Chloride) sheet. The transparent weather-resisting PVC sheet comprises the following raw materials in parts by mass: 100 parts of polyvinyl chloride, 2-8 parts of thermal stabilizing agent, 0.2-0.5 part of inner lubricant, 0.1-0.8 part of outer lubricant, 3-10 parts of weather-resisting modifying agent, 0.3-0.8 part of organic auxiliary stabilizing agent, 0.4-0.8 part of processing modifying agent and 1-2 parts of plasticizing agent. The formula has the beneficial effects that the ratio of a polyvinyl chloride resin to the thermal stabilizing agent to the inner lubricant to the outer lubricant to the weather-resisting modifying agent to the organic auxiliary stabilizing agent to the processing modifying agent to the plasticizing agent is optimized, the PVC sheet produced by using the formula disclosed by the invention is good in transparency, excellent in impact resistance and good in processing property and weather resistance, and the formula can be widely applied to technical improvement of the PVC sheet and is particularly applied to study on the transparent weather-resisting PVC sheet.
Description
Technical field
The present invention relates to a kind of transparent plastics sheet material, particularly a kind of formula of transparent weather-proof PVC sheet material.
Background technology
Polyvinyl chloride whole world annual production is only second to poly plastic raw materials, be widely used in the every field in productive life, wherein transparent article is also the important Application Areas of polyvinyl chloride, not only meet the requirement of goods mechanics, the aspect of performance such as fire-retardant, and increase the attractive in appearance of goods, but due to the application of other transparent materials, transparent polyvinyl chloride goods shared share on market is less, therefore a kind of transparent weather-proof polychlorovinyl sheet material of research has good application prospect.
Due to MBS (methyl methacrylate, divinyl and styrol copolymer) solubility parameters is close with polyvinyl chloride, both thermodynamic compatibilities are good, after blend, polychlorovinyl sheet material has very high resistance to impact shock, the refractive index of MBS and polyvinyl chloride is respectively 1.528～1.540 and 1.534～1.538 in addition, therefore after both melt blendings, can reach the refractive index of homogeneous, and the visible light wavelength of particle diameter ratio of toughner MBS particle is little, thereby plasticized modifier using MBS as polyvinyl chloride can not affect the transparency of polyvinyl chloride, be the two keys in butadiene unit but contain unsaturated double-bond in MBS, along with the content of the increase unsaturated double-bond of its content also increases gradually, sheet material is very easily occurred under the effect of light and heat aging, thereby seem not enough at weather resistance, limit its application in some field.The present invention adopts EVA and vinyl chloride-vinyl acetate resin mixture as weather-proof properties-correcting agent, not only can significantly improve the weather resistance of polychlorovinyl sheet material, and EVA wherein also contributes to improve the toughness of sheet material, effectively avoid easily aging shortcoming of the toughness reinforcing sheet material of MBS, improve the weather resistance of sheet material, there is good application prospect.
Summary of the invention
Technical problem solved by the invention is to provide a kind of formula of transparent weather-proof PVC sheet material, the easily aging shortcoming that has overcome MBS toughening polyvinyl chloride sheet material, improves its weather resistance, improves the work-ing life of sheet material, widen the use field of product, meet the demand in market.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of formula of transparent weather-proof PVC sheet material, is characterized in that: the raw material of the described following mass fraction of transparent weather-proof PVC sheet material: 100 parts of polyvinyl chloride, 2～8 parts of thermo-stabilizers, 0.2～0.5 part of internal lubricant, 0.1～0.8 part of external lubricant, 3～10 parts of weather-proof properties-correcting agent, 0.3～0.8 part of organic auxiliary stabilizer, 0.4～0.8 part of modifier, 1～2 part, softening agent.
Described thermo-stabilizer is Ca-Zn composite heat stabilizer, is the higher fatty acid calcium salt of powder shaped and the compound of zinc salt, comprises stearate, month silicate, zincate, phosphite.
Described internal lubricant is the liquid lubricant of the compound ester of the inclined to one side lipid acid of glycerine.
Described external lubricant is polyethylene wax.
Described weather-proof properties-correcting agent is the mixture of EVA (ethylene-vinyl acetate copolymer) and vinyl chloride-vinyl acetate resin (vinyl chloride-vinyl acetate copolymer), its ratio is EVA: vinyl chloride-vinyl acetate resin=1.5:2, in improving material weather resistance, also be a kind of anti-impact modifier, contribute to improve the shock resistance of material.
Described organic auxiliary stabilizer is the mixture of any one or two kinds in organic nontoxic oxidation inhibitor phenylbenzene-iso-octyl phosphorous acid ester, tetramethylolmethane two polyester, triphenyl phosphite.
Described modifier is the one in methyl methacrylate (MMA)/acrylate copolymer, methyl methacrylate (MMA)/styrol copolymer, vinyl cyanide/styrol copolymer.
Described softening agent is the one in dioctyl phthalate (DOP), dibutyl phthalate, dioctyl sebacate.
Beneficial effect of the present invention is: the present invention is optimized the ratio of polyvinyl chloride (PVC) RESINS, thermo-stabilizer, internal lubricant, external lubricant, weather-proof properties-correcting agent, organic auxiliary stabilizer, modifier, softening agent, the polychlorovinyl sheet material that adopts the formula of the present invention's proposition to produce has shock resistance, good workability and the weather resistance of the good transparency, excellence, this formula can be widely used in the technological improvement of polychlorovinyl sheet material, is specially adapted to the development of transparent weather-proof polychlorovinyl sheet material.
