Waterproof thermal-insulating heat-preservation coating and construction process thereof

Abstract

The invention relates to a waterproof thermal-insulating heat-preservation coating and a construction process thereof and to the technical field of heat-preservation materials. The waterproof thermal-insulating heat-preservation coating comprises a thermal-insulating heat-preservation component and a reflection heat-preservation component, wherein the thermal-insulating heat-preservation componentcomprises the following raw materials in percentage by weight: 36-40% of a first base filler, 16-20% of a fiber filler, 16-20% of a thermal-insulating heat-preservation functional filler, 1.6-2% of amodified bisphenol A type epoxy resin and the balance of water; and the reflection heat-preservation component comprises the following raw materials in percentage by weight: 40-44% of a second base filler, 20-24% of a reflection heat-preservation functional filler, 1-1.4% of a fluorocarbon emulsion, 0.3-0.7% of a curing agent, 0.3-0.7% of a wetting agent, 0.3-0.7% of a dispersant MF (melamine), 0.2-0.6% of a defoaming agent and the balance of water. Due to compounding of the thermal-insulating heat-preservation component and the reflection heat-preservation component, and by virtue of two different heat-preservation thermal-insulating principles, the heat-preservation thermal-insulating effects of the coating are sufficiently improved, and meanwhile, due to synergetic effects of the two components, the waterproof effect of the coating is improved, and the heat-preservation thermal-insulating properties of the coating are further improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a waterproof thermal insulation coating and a construction process thereof. Background technique [0002] In recent years, due to the rapid development of the economy, the energy competition has become increasingly fierce, and the energy problem has become a bottleneck restricting my country's economic development. In order to effectively alleviate the energy problem, energy saving and consumption reduction have been paid more attention to. One of the important measures of energy saving. [0003] Thermal insulation coatings combine the dual characteristics of coatings and thermal insulation materials, and have many advantages, such as simple coating production process, low thermal conductivity, remarkable thermal insulation effect, relatively simple construction, and are especially suitable for heat preservation of special-shaped equipment that is difficult to...

Problems solved by technology

[0004] However, the existing silicate thermal insulation coatings are generally prepared from perlite as the matrix filler. Due to its own characteristics, perlite has problems such as low strength, easy to break and easy to absorb water. After it absorbs water, its strength and thermal insulation will be greatly affected, resulting in the reduction of thermal insulation properties of silicate thermal insulation coatings
