Abstract

The invention discloses a magnetic sterilizing heat-insulation coating and a preparation method thereof. The magnetic sterilizing heat-insulation coating is prepared from, by weight percent, 15-30% of acrylic emulsion, 8-15% of hollow glass beads, 8-18% of magnetic-wave absorbing-sterilizing assistant, 8-18% of SiO2 based heat insulation composite fiber, 5-10% of rutile titanium dioxide, 5-10% of sea-foam stone powder, 5-10% of calcined kaolin, 1-2% of dispersing agent, 1-2% of anti-foaming agent, 2-5% of thickening agent, and 15-30% of water. Through nanometer modified technology, the magnetic-wave absorbing-sterilizing assistant and the SiO2 based heat insulation composite fiber are introduced to a heat-insulation coating domain, thus the multifunctional property of the heat-insulation coating is significantly widened; the coating has relatively ideal heat insulation effect while is toxic-free, odor-free, magnetic, wave-absorbable, green and environment-friendly, sterilized, self-cleaning, fire-proof and flame-retarding, and heat-resisting, and other functions; besides, the magnetic sterilizing heat-insulation coating has good market application prospect in the field of internal and external wall coatings of a building.

Description

technical field [0001] The invention relates to a magnetic bactericidal thermal insulation coating and a preparation method thereof, belonging to the technical field of preparation of chemical coatings. Background technique [0002] Since the beginning of the 21st century, the energy crisis has become increasingly serious, and the overexploitation and wanton waste of energy resources has become a hot issue restricting the development of modern society. The development of building energy-saving and thermal insulation materials is considered to be an effective means to alleviate the energy shortage and solve the energy shortage problem. According to the main conduction mode of wall thermal insulation materials, thermal insulation materials can be roughly divided into reflective thermal insulation materials, radiation thermal insulation materials, barrier thermal insulation materials and other thermal insulation materials. Vigorously expanding the variety system and applicatio...
