Abstract
The invention discloses a kind of heat shrink films.The heat shrink films are made up of the raw material of following parts by weight: 52-68 parts of modified epoxy, 15-22 parts of polyethylene, 5-17 parts of zinc stearate, 3-8 parts of vegetable oil, 1-3 parts of paraffin, 9-14 parts of adipic acid, 4-9 parts of isocyanates, 2-7 parts of silica, 3-5 parts of acrylate, 2-4 parts of lubricant, 1-6 parts of plasticizer, 1-2 parts of toughener, 8-13 parts of ethylene propylene diene rubber, 5-11 parts of kaolin, 10-15 parts of sweet potato.Heat shrink films provided by the invention tensile strength with higher and shrinkage, material recoverable, safety and environmental protection have unexpected technical effect.
Description
Technical field
The invention belongs to fields, are related to, and in particular to a kind of heat shrink films.
Background technique
Shrinkable film paracentesis resistance with higher, good shrinkage and certain shrinkage stress.It is mainly used for various
The sale and transportational process of product, for consolidating, covering and protecting product.It is beautiful to shrink-wrap not only appearance, Er Qieqi
To moisture-proof, dust-proof, loosening, antitheft, the effect of set.
Polyvinyl chloride, English abbreviation PVC are the thermoplastic resins being polymerized under initiator effect by vinyl chloride, are
The homopolymer of vinyl chloride.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin.PVC is amorphous structure
White powder, the degree of branching are smaller.Industrial PVC molecular weight has biggish more points generally in 50,000-12 ten thousand ranges
Dissipate property, the reduction of molecular weight with polymerisation temperature and increase；Without definite melting point, 80-85 DEG C starts to soften, and 130 DEG C become viscoelastic state,
160-180 DEG C starts to be changed into viscous state；There are preferable mechanical performance, tensile strength 60MPa or so, impact strength 5-10kJ/
m2；There are excellent dielectric properties.But it is poor to the stability of light and heat, in 100 DEG C or more or through a long time exposure in sunshine, Jiu Huifen
It solves and generates hydrogen chloride, and further autocatalysis is decomposed, and causes to change colour, physical mechanical property also declines rapidly, is actually answering
Stabilizer be must be added in improve the stability to light and heat.PVC is very hard, and dissolubility is also very poor, can only be dissolved in hexamethylene
In the minority solvents such as ketone, dichloroethanes and tetrahydrofuran, stable to organic and inorganic acid, alkali, salt, chemical stability is with using
The raising of temperature and reduce.
Summary of the invention
