Abstract
The invention discloses a low-density plastic thin film which comprises the following components in percentage by mass: 80-90 percent of polyethylene resin, 8-15 percent of linear low-density polyethylene resin and 2-5 percent of an auxiliary agent, wherein the polyethylene resin is low-density polyethylene resin; the auxiliary agent is a styrene-acrylonitrile copolymer. The invention provides the low-density plastic thin film; polyethylene resin is used as a main raw material; by adding of the linear low-density polyethylene resin, the low-density plastic thin film not only has high electric insulation property of a common low-density plastic thin film, but also has higher mechanical property of a linear low-density plastic thin film; the tensile strength is greatly improved; the low-density plastic thin film is high in flexibility, extensibility and transparency, is also higher in tensile strength, impact strength, puncturing strength and low-temperature impact strength and can resist oxygen and optical aging; when products with the same strength are manufactured, the cost can be reduced.
Description
Technical field
The present invention relates to plastics film field, particularly relate to a kind of Low density plastic film.
Background technology
Along with the development of society and the raising of people's living standard, the classification of product is more and more thinner, and the packaging for product is not merely confined in visual effect, but will according to the demand in the feature of product and market, towards functionalization, diversified future development.In recent years, the progress of technology makes the functionalization development trend of plastic film day by day obvious, and the plastic film of high request, high technology content is just becoming mainstay industry and the R&D target of many enterprises.Its packaging function is various, and except requiring antistatic, the antiblocking of general film and smoothness, the adjustment mainly through starting material, auxiliary agent or technique gives packaging film some special function.
Existing Low density plastic film has good chemical stability, has corrosion-resistant effect to acid, alkali and salts solution.Its electrical property and good, having that electric conductivity is low, specific inductivity is low, dielectric loss is low and the characteristic such as dielectric strength is high, is the coating material of electric wire.Along with the progress of science and technology, the day by day serious of environmental pollution, the environment for use of electric wire is also increasingly severe, but the resistance toheat of Low density plastic film is poor, and also not oxytolerant and photoaging, physical strength is lower, can not meet the demand of currently available products.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Low density plastic film, has excellent electrical insulation capability and mechanical property, can oxytolerant and photoaging, as the coating material of electric wire.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of Low density plastic film, comprise the following ingredients formed by mass percentage:
Polyvinyl resin 80-90%,
Linear low density polyethylene resin 8-15%,
Auxiliary agent 2-5%.
Described polyvinyl resin is ldpe resin.
Described auxiliary agent is styrene-acrylonitrile copolymer.
The invention has the beneficial effects as follows:
Present invention is disclosed a kind of Low density plastic film, employing polyvinyl resin is main raw material, add linear low density polyethylene resin, it is made not only to possess the good electrical insulating property of Low density plastic film, possesses again the mechanical property that linea low density plastics film is higher, tensile strength is improved greatly, not only there is good flexibility, extensibility and the transparency, also there is higher tensile strength, impact strength, puncture strength and low-temperature impact-resistant performance, and can oxytolerant and photoaging, when manufacturing the goods of same intensity, can reduce costs.
