Fireproof heat-insulated board with inorganic light aggregates and preparation method thereof

Abstract

The invention discloses a fireproof heat-insulated board with inorganic light aggregates and a preparation method thereof. The fireproof heat-insulated board is prepared by mixing 100 parts of the inorganic light aggregates, 5-15 parts of modified inorganic polymer powder, 0.1-0.3 parts of organic silicon water repellent, 0.5-1 part of a curing agent and 80-120 parts of water, and carrying out compression moulding and curing on a mixture. The fireproof heat-insulated board provided by the invention reaches the need of the incombustible-type (Grade A) uniform fireproof heat-insulated material, wherein the thermal conductivity of the fireproof heat-insulated board is smaller than or equal to 0.07W / m.k; the stability of the fireproof heat-insulated board is lasting; the mechanical strength and hydrophobicity of the fireproof heat-insulated board are excellent; the softening coefficient of the fireproof heat-insulated board is high; the workability of the fireproof heat-insulated board is good; and, the toughness of the fireproof heat-insulated board is good. The fireproof heat-insulated board can be prepared into large-sized board materials and can be also convenient to anchor without cracks, and has remarkable advantages in the toughness and durability compared with the similar inorganic heat-insulated boards. The preparation process provided by the invention is simple; the moulded board is cured only at a low temperature between 150 DEG C and 220 DEG C without the high-temperature thermal treatment or sintering; and, the comprehensive cost performance is high. The outer wall heat-insulated system made of the fireproof heat-insulated boards is convenient to construct, is stable in quality, saves energy and is fireproof, and the service life of the outer wall heat-insulated system is as long as the buildings. The application prospects of the fireproof heat-insulated board and the preparation method provided by the method are wide.

Description

technical field [0001] The invention relates to a building material, in particular to an inorganic lightweight aggregate fire-proof and thermal insulation board and a preparation method thereof. Background technique [0002] my country's "12th Five-Year Development Plan for New Materials Industry" emphasizes accelerating the promotion of new wall materials and inorganic fireproof and thermal insulation materials, and expanding the scale of new building materials industries. In particular, the application of "high-efficiency flame-retardant and safe thermal insulation materials" can improve the anti-seismic, fireproof and sound insulation performance of building materials, and promote the leap from traditional building materials to new energy-saving and environmentally friendly building materials. [0003] Building heat insulation is an important aspect of saving energy, improving the living environment and using functions. At present, external thermal insulation technology o...

Problems solved by technology

However, in the existing technology, in terms of ensuring the safety and fire prevention of the board, the combustion performance reaches A1 level (GB8624-2006), the thermal conductivity of the board is less than 0.07W / m·k in terms of thermal insulation, and the thermal insulation system formed has weather resistance and impact resistance. Under the premise of complying with the "Technical Regulations for Exterior Wall Thermal Insulation Engineering" (JGJ144-2004), fireproof thermal insulation panels with good construction performance and low comprehensive cost have not yet appeared in practice.
