External wall heat preservation material and preparation method thereof

Abstract

The invention discloses an external wall heat preservation material and a preparation method thereof. The external wall heat preservation material is prepared from, by weight, 30-50 parts of coal ash, 80-110 parts of Portland cement, 20-30 parts of glass fibers, 10-30 parts of polyether polyol, 20-40 parts of tri(bromophenoxy)cyanurate, 20-35 parts of a fire retardant, 15-20 parts of a smoke inhibitor, 1-5 parts of a coupling agent, 2-5 parts of a hydrophobic agent, 5-8 parts of a foam stabilizer and 5-10 parts of elastic emulsion. According to the raw material formula of the external wall heat preservation material, the waterproof heat preservation material with high compressive strength can be obtained and has excellent waterproofness, and thus the heat preservation material with high compressive strength and excellent waterproofness and heat preservation performance is provided. The heat preservation material has the advantages of heat preservation, heat insulation, sound insulation, self-cleaning, light weight, ray resistance, waterproofness, energy conservation, environment protection and high strength and accords with the development direction of compounding, multi-functionalization, energy conservation, greenization, light weight and high strength of civil engineering materials.

Description

technical field [0001] The invention relates to an external wall thermal insulation material and a preparation method thereof, belonging to the field of building materials. Background technique [0002] With the introduction of the concept of "energy saving, low carbon, and environmental protection", residential energy conservation has been paid more and more attention in my country, and the country has higher technical requirements for building exterior wall insulation, especially in recent years. High-rise building fires have frequently occurred , causing serious casualties and property damage. It is imminent to develop a flame-retardant energy-saving thermal insulation material that meets the requirements of modern buildings. [0003] Rigid polyurethane foam is a thermal insulation material with excellent performance. It has the advantages of light weight, good thermal insulation, excellent cushioning and shock absorption performance, and strong adhesion. It can be widely...

Problems solved by technology

[0004] The Chinese patent with the publication number CN 103043984 B discloses an energy-saving thermal insulation material. The patent mainly uses bricks and ceramic tiles as the base material to make rational use of resources, but it takes a lot of work to grind the bricks and tiles into powder. , and the invention is applied after molding, and the work efficiency of the installers is low; the Chinese patent with the publication number CN 104556843 A discloses a fire-proof and heat-insulating material, which is made of white bleach beads, oyster powder, centrifugal glass Fiber, ceramic wool, bentonite, polyacrylamide, penetrating agent, rare earth additives, pearl fly ash, and rock wool are prepared as raw materials. Among them, rock wool has the disadvantage of strong water absorption and high thermal conductivity, which may easily lead to poor insulation performance. Material performance degradation

The insulation materials disclosed in these two patents do not have the effects of sound insulation and radiation, and their performance is easily reduced under long-term exposure to the sun
