Lightweight composite building energy-saving thermal insulation material

Abstract

A fire-proof non-combustible composite heat-insulation material with good energy saving effect, good water proofing effect and better mechanical spraying construction effect is prepared by mixing and stirring ordinary Portland 42.5R cement with different weights, fiber brucite, magnesium silicate long fiber, wood fiber, light weight magnesium oxide, polypropylene fiber, an organic active waterproof agent, ultra light nano expansion beads, urea formaldehyde particles or polystyrene particles, adhesives, a foaming agent, a procoagulant regulating agent, silicon micropowder and a poly carboxylic acid superplasticizer, and has the appearance of dry and powdery fiber. The material can be directly spared on external walls, interior walls, roofs and staircase rooms of buildings according to a certain thickness after addition of water for mixing and stirring, has the characteristics of being thermal-insulation, energy-saving, non-combustible, environmentally-friendly, waterproof, and simple and quick in construction, is applicable to heat insulation of a variety of houses and buildings, and can achieve high efficiency and energy saving effect.

Description

[0001] Technical field: [0002] The invention relates to a novel light-weight composite building energy-saving and heat-preservation material, which is suitable for external wall heat preservation and exterior wall internal heat preservation projects of various building structures. [0003] Background technique: [0004] At present, my country mainly uses two types of products in terms of energy-saving and thermal insulation of building exterior walls. One type uses organic and flammable thermal insulation materials, which are generally board insulation materials. During construction, fixed facilities such as adhesives and steel grids need to be added, resulting in construction costs. High, flammable, volatile and falling off, the surface is prone to cracks, water seepage, and thermal insulation performance reduction; the other type is inorganic thermal insulation mortar, which has good fireproof performance, but high thermal conductivity, poor thermal insulation performance, an...

Problems solved by technology

[0004] At present, my country mainly uses two types of products in terms of energy-saving and thermal insulation of building exterior walls. One type uses organic and flammable thermal insulation materials, which are generally board insulation materials. During construction, fixed facilities such as adhesives and steel grids need to be added, resulting in construction costs. High, flammable, volatile and falling off, the surface is prone to cracks, water seepage, and thermal insulation performance reduction; the other type is inorganic thermal insulation mortar, which has good fireproof performance, but high thermal conductivity, poor thermal insulation performance, and poor waterproof and impermeable performance. , construction only depends on manual application, limited by the thickness of each application, resulting in backward construction methods, not suitable for use in severe cold and cold areas
