Composite heat-preservation material with kieselguhr and preparation method of composite heat-preservation material

Abstract

The invention discloses a composite heat-preservation material with kieselguhr and a preparation method of the composite heat-preservation material. The composite heat-preservation material is prepared from the following main components, namely perlite, polystyrene foam granules, hydrogenated butadiene-acrylonitrile rubber and kieselguhr, and semi-hydrated gypsum, methyl vinyl silicone rubber, diallyl phthalate, sucrose acetate isobutyrate, ethylparaben, cetyl trimethyl ammonium bromide, o-hydroxymethylbenzoic acid lactone, polypropylene fiber, polyimide fiber, an adhesive, a surfactant and distilled water through processes such as ball milling, vacuum stirring, heating stirring and pressing molding, and thus the prepared composite heat-preservation material is high in adhesive strength, sufficient in toughness and good in heat-preservation effect, is capable of meeting industrial requirements, and has relatively good application prospects.

Description

technical field [0001] The invention relates to the technical field of energy-saving thermal insulation materials, in particular to a composite thermal insulation material added with diatomite 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 promulgat...

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

[0006] There are still many deficiencies in the use of thermal insulation materials, which have brought many restrictions to the application of the above materials, making the overall building unable to achieve the ideal quality level, and at the same time bringing great challenges to the realization of the overall goal of building energy conservation
