Composite with high compressive strength and preparation method of composite

Abstract

The invention discloses a composite with high compressive strength and a preparation method of the composite. Portland cement, perlite, hydroxyethyl cellulose ether and ceramic powder are taken as main ingredients and mixed with vermiculite, polytetrafluoroethylene, lauryl dimethyl amine oxide, triethanolamine, phthalide, aluminium silicate pyrocotton, polypropylene fibers, hydrogenated castor oil, zinc stearate, an adhesive, a surfactant and distilled water under assistance of ball milling, vacuum stirring, heating stirring, press forming and other processes, so that the prepared composite has high compressive strength, good adhesion strength and good thermal insulation effect, can meet requirements of the industry and has better application prospects.

Description

technical field [0001] The invention relates to the technical field of energy-saving thermal insulation materials, in particular to a composite material with high compressive strength 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 promulgated specia...

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
