Antibacterial and thermal insulation material and preparation method thereof

Abstract

The invention discloses an antibacterial and thermal insulation material and a preparation method thereof. The material is prepared from the following components by weight: 40-50 parts of vinyl esterresin, 10-15 parts of modified melamine resin, 20-35 parts of rubber, 10-15 parts of organic silicon microspheres, 2-5 parts of an inorganic antibacterial agent, 5-8 parts of a flame retardant, 3-7 parts of chitin, 0.2-0.5 part of a defoaming agent, 4-6 parts of nano calcium carbonate, 0.5-1.2 parts of a film-forming assistant, 2-4 parts of a pH regulator and 3-6 parts of an assistant. The inorganic antibacterial agent is one of or a mixture of several of zeolite-loaded silver, zirconium phosphate-loaded silver or nano-zinc oxide. The invention relates to the technical field of building materials. The antibacterial and thermal insulation material is set with multiple sterilization cost, the antibacterial capacity of the material can be improved, through the inorganic antibacterial agent, the bactericidal capacity of the material can be improved, through chitin, the growth of bacteria on the material can be inhibited, and chitin has natural bacteriostatic effect and a very high broad-spectrum antibacterial rate, and chitin and the inorganic antibacterial agent are insoluble in water and dilute acid.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an antibacterial heat insulation material and a preparation method thereof. Background technique [0002] Building energy conservation specifically refers to the implementation of energy-saving standards in the planning, design, new construction, renovation and use of buildings, the adoption of energy-saving technologies, processes, equipment, materials and products, and the improvement of thermal insulation performance and heating, air-conditioning and refrigeration. Heating system efficiency, strengthen the operation and management of building energy systems, use renewable energy, and increase the thermal resistance of indoor and outdoor energy exchange under the premise of ensuring the quality of the indoor thermal environment, so as to reduce the heating system, air conditioning, cooling and heating, The energy consumption of lighting and hot water supply due to a ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an antibacterial thermal insulation material and a preparation method thereof, which solves the problem that most of the existing building materials do not have antibacterial ability or have only single antibacterial ability, which leads to the building materials being easily damaged in a humid environment. Bacteria are bred, and the spores of bacteria are easy to spread with the air, which can easily cause diseases or allergies. At the same time, the existing building materials have weak heat resistance and heat insulation capabilities.
