Heat preservation decorative composite board finish material and preparation method thereof

Abstract

The invention discloses a heat preservation decorative composite board finish material and a preparation method thereof. A finish material premix of the heat preservation decorative composite board finish material comprises the following components by weight: 10-30 parts of ordinary silicate white cement, 10-50 parts of aluminum-containing cement, 0.1-0.2 part of a retarder and 3-7 parts of an adhesive, wherein the aluminum-containing cement includes at least one of aluminate cement and sulphoaluminate cement. A finish material slurry obtained by mixing of the finish material premix with watercan have good setting and hardening performance and bonding capacity, and then can realize bonding with a heat insulation board or a slurry of the insulation board under a plasticizing state, a unified whole is formed after curing molding, and secondary bonding of a heat insulation board and a decorative surface material with an adhesive is unnecessary, the heat preservation decorative compositeboard obtained by one-time molding can have good interlayer bonding performance and high bonding strength, and the decorative surface layer has high strength, small deformation and good integration.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a thermal insulation decorative composite panel facing material and a preparation method thereof. Background technique [0002] In order to meet the needs of thermal insulation and surface decoration at the same time, traditional thermal insulation materials combine thermal insulation materials and decorative materials together. It must realize effective connection between thermal insulation materials and decorative materials to ensure sufficient resistance after combination. Improve the bonding strength and further ensure the safety of building exterior walls. The facing materials for general decoration include: calcium silicate board, glass magnesium board, cement fiber board, ceramic tile, stone, etc. surface); core insulation materials include: polystyrene board, extruded board, graphite modified polystyrene board, rock wool, cement foam board, foam glas...

AI Technical Summary

Problems solved by technology

The facing materials for general decoration include: calcium silicate board, glass magnesium board, cement fiber board, ceramic tile, stone, etc. surface); core insulation materials include: polystyrene board, extruded board, graphite modified polystyrene board, rock wool, cement foam board, foam glass, thermosetting composite polystyrene board, homogeneous modified fireproof insulation board etc.; the traditional method generally uses organic glue to bond the core insulation material and the decorative surface material to ensure high bonding strength, but the organic glue has aging, falling off, insulation core material and decorative surface under long-term outdoor operating conditions. layer detachment; at the same time, the VOC emission exceeds the standard, requiring a complicated process of secondary pasting, and the product stability is not guaranteed

In addition, when the facing material is made of organic materials, the thermal insulation effect is good, but the fireproof performance is poor, and there are serious safety hazards. When the facing material is made of inorganic materials, it is easy to absorb water and deform, slag falls and pulverizes, and the thermal conductivity is high. , energy-saving standards are difficult to meet the needs of the current design indicators
