Abstract

The invention relates to the technical field of coatings and in particular to a thermal-insulating flame-retardant waterproof coating which comprises the following substances in parts by weight: 100 parts of an epoxy resin, 10-25 parts of amino modified quartz powder, 20-42 parts of sepiolite, 5-10 parts of a flame retardant, 80-150 parts of reinforcing fibers, 0.5-3 parts of a surfactant and 100-150 parts of a solvent, wherein the reinforcing fibers comprise a reinforcing fiber A and a reinforcing fiber B; the diameter of the reinforcing fiber A is 10-50nm; the length of the reinforcing fiberA is 0.5-2mu m; the diameter of the reinforcing fiber B is 100-300nm; the length of the reinforcing fiber B is 3-5mu m. As an epoxy substrate is doped with reinforcing fibers which are different in diameter and length, a meshed structure is formed, and the coating is excellent in thermal insulation effect; meanwhile the amino modified quartz powder can be matched with the reinforcing fibers to form a reinforced framework, the overall toughness and the strength of the coating are improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a heat-insulating and flame-retardant waterproof coating. Background technique [0002] As a new type of building material, coatings are widely used in the decoration and decoration of buildings such as interior and exterior walls, floors, roofs, pipes, etc., and their functions are also different according to different applications. [0003] Due to sunlight, the temperature inside the building rises, which will inevitably increase the energy consumption of the air conditioner. In addition, industrial plants, mobile homes or temporary buildings often use metal steel roofs. Under the sunlight, the indoor temperature rises. The speed is very fast. In many cases, the effect of using air conditioning to reduce the indoor temperature is not good. It is usually the most practical way to reduce the indoor temperature by lowering the temperature of the roof surface. The main method to p...
