A phenolic fireproof insulation block

Abstract

The invention relates to a phenolic aldehyde fireproof thermal insulation block. The phenolic aldehyde fireproof thermal insulation block is prepared from the following raw materials in parts by weight: 60-85 parts of a main body, 10-25 parts of thermoplastic phenolic aldehyde resin, 10-20 parts of a curing agent, 5-15 parts of a composite flame retardant, 3-5 parts of antimonous oxide, 8-10 parts of aluminum dihydrogen phosphate and 2-10 parts of inorganic crystal whiskers. The prepared phenolic aldehyde fireproof thermal insulation block has comprehensive performances and advantages of being fireproof and non-combustible, light in weight, high in strength, low in heat conduction coefficient, durable, good in thermal insulation effect and convenient in construction, not only can be used for a building lower than 100m, but also can be used for various buildings over 100m, so that the combustion performance achieves level A.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to a phenolic fireproof and thermal insulation block applied to building thermal insulation. Background technique [0002] Insulation materials for building insulation mainly include two categories: self-insulation of walls and external insulation of external walls (including organic materials and inorganic materials). Among them, the inorganic thermal insulation materials used for wall self-insulation mainly include aerated concrete blocks, which adopt the masonry thermal insulation construction method, while the inorganic thermal insulation materials for external wall thermal insulation are light-weight expanded perlite, expanded vitrified microbeads, silica Algae earth and sepiolite are the main insulation materials, together with cement as the gelling agent, and fiber as the anti-cracking material.

AI Technical Summary

Problems solved by technology

[0003] The biggest advantage of all inorganic thermal insulation materials is that they are used for building thermal insulation, fireproof, non-combustible, and have good mechanical strength. The disadvantages are that although they have thermal insulation effects, they have high thermal conductivity (that is, large application thickness) and poor thermal insulation effects.

[0004] When inorganic thermal insulation materials are used for wall insulation, according to the energy-saving rate stipulated by the relevant national competent industries, the thickness of the thermal insulation material must be increased, and because of its large bulk density, it not only increases the building load, but also brings many problems to the construction. inconvenient

[0005] When conventional organic insulation materials are used for wall insulation, they have the characteristics of light weight, high strength, low thermal conductivity, good insulation effect and convenient construction, but their fire performance is lower than that of inorganic insulation materials. According to the current national regulations on building external insulation systems, Buildings above 100 meters (super high-rise) must use non-combustible (A-level) insulation materials. Therefore, organic insulation materials are not yet non-combustible (A-level), and can only be used for building heights below 100 meters.
