Abstract

The invention discloses a vitrified micro-bubble phenolic foam thermal insulation size comprising re-dispersible latex powder thermal insulation material and lightweight aggregate in the weight ratio of 1:(0.6-0.8); the lightweight aggregate comprises vitrified micro-bubbles and phenolic foam in the weight ratio of (0.4-0.75):1; the re-dispersible latex powder thermal insulation material comprises the following components of: 13-15kg of re-dispersible latex powder, 3-8kg of cellulose ether, 0.5-1.5kg of waterproofing agent, 80-100kg of coal ash, 0.5-2kg of glass fibre, 420-450kg of cement and 100-150kg of quartz sand. The vitrified micro-bubble phenolic foam thermal insulation size provided by the invention as a thermal insulation material of an exterior wall of a building has a good thermal insulation effect and the thermal coefficient of less than or equal to 0.05W / m.K; and the vitrified micro-bubble phenolic foam thermal insulation size has a high fireproofing grade and fireproof performance up to the A2 grade.

Description

technical field [0001] The invention relates to a building material, in particular to a vitrified microbead phenolic foam thermal insulation slurry with good thermal insulation effect and high fireproof rating. Background technique [0002] In the prior art, the thermal insulation materials for building exterior walls are generally organic materials (such as polyurethane, polystyrene insulation boards, etc.), although the thermal insulation effect is good, but the fire protection level is low, and the sparks generated by pyrotechnics, electric welding or metal cutting, etc. It is easy to ignite the insulation material of the building's outer wall, thereby causing a fire accident. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a vitrified microbead phenolic foam insulation slurry with good heat preservation effect and high fire resistance level, so as to reduce fire accidents caused by igni...
