Heat preservation and waterproof material with good stability

Abstract

The invention discloses a heat preservation and waterproof material with good stability. The heat preservation and waterproof material includes the following substances by weight: 30-50 parts of sepiolite, 14-19 parts of scallop shell powder, 3-5 parts of nonionic acrylic acid, 7-8 parts of perforated expanded perlite, 20-35 parts of organosilicon modified epoxy resin, 5-9 parts of sodium stearate, 1-9 parts of graphite powder, 1-6 parts of polypropylene fiber, 3-7 parts of hydroxypropyl methyl cellulose, 3-9 parts of a titanate coupling agent, 3-5 parts of pentaerythritol, 2-8 parts of silicon carbide, 20-32 parts of aluminum silicate powder, 1-6 parts of a core-shell polymer polymerized emulsion, 3-9 parts of a higher fatty acid salt, 1-3 parts of hollow glass beads, and 8-15 parts of nonionic acrylic acid. The heat preservation and waterproof material provided by the invention has the advantages of good hydrophobicity and heat-insulating properties, high compressive strength, tensile strength and flexural strength, obviously improved water retention and anti-cracking functions, good flame retardance and acid and alkali resistance, and greatly improved corrosion resistance and oxidation resistance.

Description

technical field [0001] The invention belongs to the field of energy-saving and environment-friendly materials, and relates to a thermal insulation and waterproof material with good stability. Background technique [0002] As people have higher and higher requirements for house heat insulation, heat insulation and waterproof technology has gradually developed into a systematic building energy-saving technology, which is used to improve living comfort, prolong building life, prevent heating heat and cold air loss, thereby reducing Energy consumption; the current insulation materials have poor water-repellent properties. Once rainwater seeps into the insulation material layer, it will be absorbed in the insulation layer and cannot come out, which will easily lead to hollowing and delamination of the material, bursting or even mildew. In addition, building materials Easy to corrode, poor acid and alkali resistance, unstable performance. Contents of the invention [0003] In...
