Building wall anti-corrosion thermal insulation material and preparation method thereof

Abstract

The invention discloses a building wall anti-corrosion thermal insulation material and a preparation method thereof, and relates to the field of thermal insulation materials. The building wall anti-corrosion thermal insulation material is prepared from raw materials, in parts by weight: 60-70 parts of polyurethane, 40-50 parts of phenolic resin, 10-18 parts of sepiolite, 8-16 parts of glass fiber,6-12 parts of wood fiber, 5-8 parts of rock wool, 9-16 parts of portland cement, 6-12 parts of expanded clay, 5-10 parts of zinc oxide, 5-10 parts of magnesium oxide, 4-9 parts of nanometer titania,4-9 parts of nanometer silicon carbide, 8-15 parts of potsherd, 8-15 parts of aerogel, 6-12 parts of mica powder, 7-15 parts of glass bead, 3-6 parts of ammonium polyphosphate and 3-6 parts of ammonium dihydrogen phosphate. The building wall anti-corrosion thermal insulation material has the outstanding performance, good anti-corrosion, anti-pressure and anti-seismic properties, low thermal conduction coefficient, good thermal insulation performance, and meanwhile the waterproof and anti-aging properties, in addition, the raw material cost is low, the preparation method is simple, and the material is easy to be put into scale production.

Description

technical field [0001] The invention relates to the field of thermal insulation materials, in particular to a corrosion-resistant thermal insulation material for building walls and a preparation method thereof. Background technique [0002] Promoting the use of wall insulation technology is one of the effective ways to reduce energy consumption in our country. At present, the approximate proportion of energy loss in houses in our country is: walls account for 50%; roofs account for 10%; doors and windows account for 25%, basements and grounds account for about 15%. Therefore, the insulation of walls and roofs is an important factor to improve the energy-saving rate of buildings. How to choose safe and environmentally friendly wall insulation building materials is one of the hot spots that the industry pays close attention to today. [0003] Under the requirements of residential environment safety and environmental protection, my country's building energy-saving rate is inc...

Problems solved by technology

[0003] Under the requirements of residential environment safety and environmental protection, my country's building energy-saving rate is increasing year by year, but at present, my country's building insulation materials are mainly organic materials, of which polystyrene has a market share of 90%, but polystyrene insulation materials There are disadvantages of poor material strength, prone to cracking, and falling off of the insulation layer. At the same time, the polystyrene foam insulation board has poor load-bearing capacity due to its limited strength.
