Building material with air purification function and preparation method thereof

Abstract

The invention provides a building material with an air purification function and a preparation method thereof, which relates to the technical field of building materials. The building material with the air purification function is prepared from the following raw materials in parts by weight: 60 to 70 parts of polyurethane high polymer material, 9 to 17 parts of pulverized fuel ash, 10 to 14 parts of ethyl petrol stearate, 5 to 15 parts of palmitic acid, 2 to 4 parts of nanosilicon dioxide, 2 to 4 parts of nano calcium carbonate, 10 to 16 parts of nanometer titania, 9 to 15 parts of nano-zinc oxide, 6 to 10 parts of activated carbon, 5 to 9 parts of bentonite, 4 to 8 parts of boron fiber, 6 to 8 parts of polypropylene fiber, 3 to 5 parts of kieselguhr, 0.3 to 0.9 part of heat stabilizer, 0.5 to 0.9 part of light stabilizer, 0.5 to 0.9 part of coupling agent, 0.3 to 0.7 part of antioxidant, and 0.4 to 0.6 part of foaming agent. The preparation method comprises the following steps of (1) weighing the raw materials; (2) preparing a mixture a; (3) preparing a mixture b; (4) preparing a mixture c; (5) entering a mould for forming. The building material with the air purification function and the preparation method thereof provided by the invention solve the problem that the functions of air purification, compression resistance, tensile strength and heat insulation of an existing building material need to be improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a building material with the function of purifying air and a preparation method thereof. Background technique [0002] Along with social progress and the improvement of people's living standards, air pollution is becoming more and more serious, seriously endangering human health, and building materials are the most frequently contacted materials in people's life and work. People's requirements for building materials Higher and higher, especially building materials with superior air purification function, however, existing building materials are not effective in purifying air. [0003] In addition, due to the wide range of uses of building materials, in addition to the above-mentioned air purification performance, their compressive, flexural and tensile properties also need to be further strengthened, so that the functions of building materials are diversifi...
