Description
Technical field:
The present invention relates to the shrink-down material that insulate, a kind of air collapsible tube that elastic memory can shrink in the air of normal temperature and pressure automatically that has is provided especially.
Background technology:
The insulation shrink-down material owing to have elastic memory, can make be insulated material obtain well coated, thereby improved the reliability of insulation, obtained to use widely in fields such as electric power, communication, traffic, petrochemical industry, military project, buildings.At present, widely used insulation shrink-down material is a kind of heat-shrinkable tube on market, the ubiquity following problems: 1, in use need to be equipped with heavy heating tool such as baking box, spray gun; 2, because the bad grasp of shrinkage temperature needs masterful technique type operating personnel; Even 3 best operating personnel, also can not be with heating and temperature control very even, those special-shaped workpieces particularly, contractive effect can not effectively be guaranteed.
The technology contents of invention:
The object of the present invention is to provide a kind of air collapsible tube, its contraction simple to operate is even, thereby use cost is low, end product quality is good.
The invention provides a kind of air collapsible tube, it is characterized in that this air collapsible tube is made of the sleeve pipe that is soaked in the chemical pretreatment solution, wherein:
The main component of sleeve pipe is parts by weight:
40～65 parts of polyvinyl chloride

0.1～5.0 part of white carbon black.
The effect of each component is respectively: high anti-polystyrene modifier, solid paraffin lubricant, epoxy-ester stabilizing agent and plasticizer, antimony oxide fire retardant, chlorinated paraffin wax plasticizer and fire retardant, white carbon black light stabilizer.
In order to match with different air collapsible tube, in the air collapsible tube of the present invention, the chemical treatment formula of liquid also can be adjusted, and other contains: one or more of dibutyl phthalate, ethylene acetate, methyl alcohol, and their content is respectively:
10～20 parts of dibutyl phthalates
5～10 parts of ethylene acetates
0.1～10 part of methyl alcohol.
The present invention gives product with good and unique attribute by design cleverly, and main feature has:
1, operation is very easy
Need not heavy heating tool such as baking box, spray gun during operation, only need one scissors got final product, also need not poly-talented operating personnel.
2, shrink definitely evenly
The air collapsible tube is after the characteristic solvent is handled, and the expansion deliquescing is placed on that the back is along with the volatilization of solvent is shunk automatically in the air, and immanent air shrinks it simultaneously with speed on all directions, and contractive effect is definitely even, is applicable to the workpiece of arbitrary shape.
3, cost reduces
Simple to operate, shortened the construction period, for the user has saved personnel and energy consumption cost, in addition, this product is compared with other shrink-down materials and has been realized indefinite length, can intercept arbitrarily according to user's needs, has saved unnecessary waste of material.
4, properties of product are good
In each side such as electric, physics, chemical properties, product of the present invention has has all met or exceeded other insulation shrink-down material, has waltzed through the detection of national relevant authoritative department.
