Description
Technical field
The present invention relates to a kind of plastic material technical field, a kind of corrosion-resistant cold-resistant high temperature resistant waterproof film.
Background technology
Use high density polyethylene (HDPE) (High Density Polyethylene, referred to as " HDPE ") in the market more
As waterproof layer, carrying out film use in traditional HDPE woven film, this surface film tarpaulin drenches lepthymenia, makes tarpaulin
Not there is water proofing property, only possess basic splash-proof ability.At present polyethylene tarpaulin inner substrate part be polyethylene filament via
Braider be longitude and latitude braiding form, inside and outside spray Low Density Polyethylene (LDPE) liquation, through calendering formed thin film, base
Material plays raising thin film pull resistance, and film then plays primary watertightness effect.This tarpaulin strengthens the use intensity of thin film, but
Water proofing property aspect, does not make further performance and improves.
This polyethylene tarpaulin is possible to prevent the process that dabbles of transience, but cannot meet the most waterproof, seepage control project and want
Ask, in reality produces, rarely have enterprise to use as waterproof layer, and often dust-proof block as job site is temporary,
Or play sunshade effect during a property time uses.
Traditional material substrate is HDPE, and production technology is braiding；Two sides film is LDPE, and production technology is spray, two
Person rolls together through equipment.But this is that kind of a material, production technology are the most entirely different after all, can cause film and the base material can not
Fully laminating, easily tears, is easily generated seepage, two kinds of material separation easy to foaming.
Summary of the invention
It is an object of the invention to provide a kind of corrosion-resistant cold-resistant high temperature resistant waterproof film, for this film ethylene tarpaulin institute
The water-proof function of shortcoming, is the oriented invention of unique environments situation being had for high altitude localities, and this thin film can be
The chemical environment such as the most saline and alkaline plays long-term antiseepage effect.High heat in summer for highlands has fabulous being suitable for winter severe cold
Property, can go through for many years and retention performance is constant.
For achieving the above object, the present invention provides following technical scheme:
A kind of corrosion-resistant cold-resistant high temperature resistant waterproof film, is made up by the mass ratio of 2:6-10 with LDPE of additive, Qi Zhongtian
Add agent to be made up of according to the raw material of mass percent following:
Ethene-vinyl acetate/polyethylene octene elastomer 15-21%
Ethylene vinyl acetate thing 35-41% altogether
Polyolefin elastomer 25-31%
Linear low density polyethylene 8-12%
Ultra-high molecular weight polyethylene 4-8%.
As the further scheme of the present invention: vinyl acetate content in ethene-vinyl acetate/polyethylene octene elastomer
It is 14%.
As the further scheme of the present invention: additive is 2:8 with the mass ratio of LDPE.
As the further scheme of the present invention: additive is made up of according to the raw material of mass percent following:
Ethene-vinyl acetate/polyethylene octene elastomer 18%
Ethylene vinyl acetate thing 38% altogether
Polyolefin elastomer 28%
Linear low density polyethylene 10%
Ultra-high molecular weight polyethylene 6%.
As the further scheme of the present invention: the preparation process of additive is: by ethene-vinyl acetate/polyethylene octene
Elastomer, ethylene vinyl acetate thing, polyolefin elastomer, linear low density polyethylene, ultra-high molecular weight polyethylene altogether is pressed altogether
After weighing according to the ratio of mass percent, it is injected into fuse machine, agitating heating under the hot melting temperature of 200 DEG C, all it is fused into
Liquid, after extrusion, reduces temperature through cooling device, takes mould to be pressed into tabular simultaneously, then is cut into graininess and i.e. obtains and add
Add agent.
In the present invention vinyl acetate content be 14% ethene-vinyl acetate/polyethylene octene elastomer make thin film have
There is excellent anti-ultraviolet property.Ethylene vinyl acetate thing altogether increases degree of adhesion and the hot strength of thin film.Polyolefin elastomer
Increase the pliability of thin film, do not cause fracture because of folding.Linear low density polyethylene extends thin film ageing resistance, antioxidation
Ability.Ultra-high molecular weight polyethylene increases thin film wear resistence, self lubricity, water-resistance.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention be directed to existing ldpe film and be oriented compositional refinements, use the material combination of different proportion, this skill
Art is by ldpe film carries out formulation optimization, by the material modified interpolation of proper proportion so that it is have extremely strong environment
Weatherability, has the water resistance of brilliance simultaneously, simultaneously improves production technology, make film substrate combine together with two-sided film,
The most easy to crack, will not under cold and hot frequent alternate environment, unlike material material natural separation and affect water resistance.Have extremely strong
Tensile strength, meet engineering waterproofing requirement.
Newly-increased anti-ultraviolet property in thin film of the present invention, this thin film upper and lower surface has all sprayed one layer containing ultraviolet (UV) resistant agent
And the ethene-vinyl acetate/polyethylene octene elastomer of ethene-vinyl acetate content 14%.
This ethylene containing ultraviolet (UV) resistant agent and ethene-vinyl acetate content 14% of film double-sided of the present invention spray-
Vinyl acetate/polyethylene octene elastomer, so the tensile strength of polyethylene film, elongation, resistant to shearing degree, bending are very
Degree all has greatly improved, and adds ultraviolet (UV) resistant agent, and the uvioresistant index of polyethylene film is obviously improved, time long
Between be exposed to the sun by burning sun and also not had problem, convenient ultraviolet irradiates and uses under exposure environment the most regional, long-term.Thoroughly
Solve outside the adhesion problem of HDPE and LDPE bi-material, summer high temperature feature extremely cold according to the winter of highlands, there is pin
Addition multiple additives raw material to property so that it is possess cold resistant, sunburst irradiation high temperature resistant, resistance to, UV resistant, resistance to always
The features such as change, saline-alkaline corrosion-resistant.
