Anti-corrosion energy-saving heat preservation material and preparation method thereof

Abstract

The invention discloses an anti-corrosion energy-saving heat preservation material and a preparation method thereof. By taking sepiolite, mica powder, bentonite, sorbitol fatty acid ester and triallyl isocyanurate as main components and by adding ethyl O-methyl benzoate, fibre brucite, lauryl dimethyl amine oxide, polytrimethy terephthalate fiber, 2,4-diaminobenzenesulfonic acid, diethylene phosphate, sodium methyl hydroxypropyl cellulose, an adhesive, a surfactant and distilled water, under the assistance of processes of ball grinding, vacuum stirring, heating stirring, pressing forming and the like, the prepared heat preservation material is excellent in acid and alkali resistance and good in heat preservation effect, can meet the requirements of the industry and has a relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of energy-saving thermal insulation materials, in particular to a corrosion-resistant energy-saving thermal insulation material and a preparation method thereof. Background technique [0002] At present, the energy issue has become a prominent contradiction internationally. Due to the rapid economic development of our country, the contradiction between energy and environmental protection has become more prominent. my country is currently the largest construction market in the world, with an annual increase of about 2 billion m 2 Buildings, more than 95% of which are high-energy buildings, if no energy-saving measures are taken, 50% of the national energy will be consumed in buildings by 2020, which will bring huge losses to the national economy and energy. [0003] The main purpose of building energy conservation is to reduce energy consumption and reduce environmental pollution. The government has promul...

Problems solved by technology

However, there are the following main disadvantages at the same time: poor thermal insulation performance, large footprint; poor impact resistance and compressive strength; high hygroscopicity, poor environmental performance, and harmful to human body during construction and application

Polystyrene foam insulation material is a kind of thermoplastic material, which has better performance than inorganic insulation materials, but some of its shortcomings are gradually exposed in the process of use: polystyrene insulation material has a cavity structure, and the outside air can easily pass through the gaps in the air. The cavity flow affects the thermal insulation effect; the wind resistance is poor: the tensile strength of EPS is only 0.1 Mpa in dry conditions, and the tensile strength after immersion in water is lower, so EPS is generally not used in high-rise buildings; polystyrene insulation materials require storage It can be used for construction after 40 days, which is difficult to achieve in practice, so the project using EPS insulation is prone to cracks, wall moisture permeability and water return

However, composite materials are still in the research and development stage, and there is no marketization

In addition, new thermal insulation materials are being developed such as thermal insulation coatings, radiation protection coatings, etc. These materials have a certain thermal insulation effect, and some progress has been made in application, but there are limitations in their performance and application: first, the cost Second, the coating ages quickly and has a limited service life

[0005] To sum up, there are still many deficiencies in the use effect of energy-saving thermal insulation materials on the market at present, which brings many restrictions to the application of the above-mentioned materials, making the building as a whole unable to achieve the ideal quality level, and also affecting the overall building energy efficiency. Achieving the goal brings with it no small challenge
