Waterproof and light-absorbing paint for building interior walls applied to indoor environment and manufacturing method thereof

Abstract

The invention discloses a building interior wall waterproof and light-absorbing coating applied to indoor environments and a preparation method thereof. The waterproof and light-absorbing coating is composed of a lyotropic liquid crystal high-molecular polymer, a water-proof and light-absorbing functional component and an additive, wherein the waterproof and light-absorbing functional component isan inorganic mixed powder mainly composed of river sand, metal ceramic powder TiN-Fe and metal iron; the additive comprises a dispersant, a physical foaming agent and a toughening agent; the dispersant is hydroxypropyl methyl cellulose, the physical foaming agent is fluorocarbon; the toughening agent is liquid ethylene propylene rubber. The waterproof and light-absorbing coating has the characteristics of being warm at night and being cool in the day, and has the advantages of subdued light effect, good veneer decoration effect, good toughness, collision resistance, good wear resistance, water resistance, environmental protection and no pollution.

Description

technical field [0001] The invention relates to the field of environmentally friendly coatings, in particular to a waterproof and light-absorbing coating for building interior walls applied to indoor environments and a manufacturing method thereof. Background technique [0002] In the prior art, there is no interior decoration coating that is warm at night and cool at day, but there are indoor coatings or decorative modules that are warm in winter and cool in summer with similar technical concepts, the most typical of which is the sea capacity building energy-saving module (abbreviated as sea capacity module). The material is a new type of energy-saving building material that uses modified expandable polystyrene particles, which are heated and foamed, and then punched and formed at one time through special equipment, molds and special processes. The sea capacity module is a module made of various specifications and shapes by using the principle of building blocks. But since...

Problems solved by technology

But since it is modular, its self-adaptability is not good, and it is inherently equipped with seams. At the same time, although this material does not release toxic and harmful gases at room temperature, it is easy to decompose toxic and harmful substances at high temperatures. At the same time, its The waterproof and anti-aging performance is poor, and the wear resistance is also relatively poor. In addition, due to the single composition, it cannot have both softness and wear resistance at the same time.

[0003] Limited by the lack of technical field and practical experience in the prior art, a complete waterproof and light-absorbing paint for interior decoration has not really appeared. Effect, decorative effect, good toughness, good toughness, anti-collision, good wear resistance, water resistance, green and pollution-free waterproof and light-absorbing paint
