Background
The traditional color steel tile waterproof material is mostly paved by waterproof cloth or laminated plastic materials, and under the conditions of high temperature and more rainwater, the materials are not only easy to peel off to cause the falling of a surface waterproof layer, but also easy to cause the rusting and the corrosion of the covered color steel tile surface layer after the falling of the surface waterproof layer, thereby further causing the corrosion and the water leakage.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model aims to provide a high weather resistance heat insulation waterproof insulation structure.
The utility model discloses the technical scheme who adopts does: a high-weather-resistance heat-insulation waterproof heat-preservation structure comprises a high-polymer anti-aging layer, a protective layer, a heat-preservation layer and an isolation layer, wherein a pressure-sensitive adhesive bonding layer is arranged between the heat-preservation layer and the isolation layer, and the anti-aging layer, the protective layer, the heat-preservation layer, the pressure-sensitive adhesive bonding layer and the isolation layer are sequentially connected; the anti-aging layer, the protective layer and the heat insulation layer are integrally formed by adopting a re-pressing process.
Preferably, the polymer aging resistant layer includes a polymer film layer.
Preferably, the high molecular polymer film layer comprises a high molecular polymer thermoplastic elastic film layer and/or a high molecular polymer thermosetting elastic film layer.

The high molecular polymer polyethylene film is one kind of thermoplastic resin prepared through polymerizing ethylene. In industry, copolymers of ethylene with small amounts of alpha-olefins are also included. The polyethylene is odorless and nontoxic, feels like wax, has excellent low-temperature resistance (the lowest use temperature can reach-100 to-70 ℃), has good chemical stability, and can resist corrosion of most of acid and alkali (cannot resist acid with oxidation property). Is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation. Has excellent environmental stress cracking resistance and electrical insulation, higher heat resistance, impact resistance, puncture resistance and the like. Polyethylene can age, discolor, crack, become brittle or chalk under the action of atmosphere, sunlight and oxygen, and lose its mechanical properties.

Has high impact resistance, high mechanical property and high resistance to corrosion of various organic solvents and acid and alkali. It is widely used in industry and is one of the common polymer materials. Has excellent moisture absorption resistance, acid and alkali corrosion resistance and dissolution resistance.
A high molecular polymer polyamide membrane is a general term for a membrane having a separation function made of a high molecular compound. From the theory of hydrophilicity and hydrophobicity, the polyphthalamide should be a better reverse osmosis membrane material, the average interchain distance is very short, the oxygen bond between the phthalein groups is very strong, and the like, so that the hydrophilicity of the polyphthalamide is damaged, and not all the polyphthalamide can be prepared into the reverse osmosis membrane.

The formaldehyde solution is stored at low temperature to slowly generate paraformaldehyde, which precipitates as white insoluble matter. Is a tough and elastic material, and has good creep resistance, geometric stability and impact resistance even at low temperature. POM has both homopolymer and copolymer materials. Homopolymer materials have good ductile strength, fatigue resistance, but are not easily processed. The copolymer material has good thermal stability, chemical stability and easy processing. Both homopolymer and copolymer materials are crystalline materials and do not readily absorb moisture. The high degree of crystallinity of POM results in a relatively high shrinkage, which can be as high as 2% to 3.5%. There is a different shrinkage for each different reinforced material.
Preferably, the high molecular polymer thermosetting elastic film layer comprises a high molecular polymer epoxy resin film layer and/or a high molecular polymer polyurethane film layer.
