Problems solved by technology

However, due to the rapid temperature rise of the dielectric, it is easy to cause local hot spots, cause carbonization, and destroy the molecules of the polymer.
Excessive temperature can ignite the paint and cause many unsafe factors
Although it has been developed to a certain extent in industrial practice, due to its high density, poor reworkability, and poor water tightness of ferrite, it is easy to decompose and change, resulting in waterproof failure.
In addition, its specificity is large, and when the viscosity of the coating becomes low after heating, it is easy to precipitate, resulting in a decrease in heating efficiency.
And its poor temperature stability
When the temperature is high, the efficacy will be greatly reduced

Abstract

The invention relates to thermoplastic macromolecule waterproof coatings, in particular relates to a thermoplastic macromolecule waterproof coating capable of being subjected to microwave heating and a preparation method thereof. The macromolecule waterproof coating capable of being subjected to microwave heating is prepared by shearing at high temperature and stirring the following components in percentage by weight: 10-50 percent of elastic thermoplastic polymer, 20-60 percent of asphalt, 5-20 percent of diluting agent, proper amount of compatilizer and 6-30 percent of absorption microwave materials. The absorption microwave materials comprise 0.5-5 percent of conducting polymer and 5-25 percent of waste vulcanized rubber powder. The macromolecule waterproof coating can be formed by the first time, so that the working period is greatly shortened, a sealing basic layer is effectively solved, the tension fracture of a waterproof layer caused by cracking of the basic layer is overcome, and the waterproofing reliability is improved; and meanwhile, the macromolecule waterproof coating can be used for multiple purposes to fully play a role in the advantages and the characteristics of respective materials, so that the process is simple and convenient, the macromolecule waterproof coating can be quickly constructed, the maintenance is avoided, and the working period is short.

Description

technical field [0001] The invention relates to a thermoplastic polymer waterproof coating, in particular to a thermoplastic polymer waterproof coating which can be heated by microwaves and a preparation method thereof. Background technique [0002] Polymer waterproof coating is an excellent material for waterproofing. The currently used polymer coatings are water-emulsified emulsion-based water-emulsion coatings. It uses cold construction, but its solid content is low, generally not exceeding (60-70%), The thickness of each application is limited by the curing conditions. It cannot be very thick. The film needs to be applied multiple times. Under humid conditions, the water in the emulsion cannot be volatilized, so it cannot be cured. very inconvenient. [0003] Modified asphalt coils such as SBS and APP coils are currently popular in the market. It needs a flame spray gun to carry out on-site surface hot melting, requires an open flame, has high technical requirements, a...
