Problems solved by technology

Although the reserves of Laizhou magnesite are abundant, the light-burned powder produced in Laizhou is unstable and cannot produce stable glass magnesium boards. Therefore, the light-burned powder used to manufacture glass magnesium boards in the prior art is mostly produced in Liaoning. As a result, the price of lightly burned powder produced in Liaoning has risen, and the price of 180-mesh lightly burned powder is 420 yuan / ton; while the price of lightly burned powder produced in Laizhou is only 380 yuan / ton, but it cannot be used because of unstable board forming technology; As far as enterprises are concerned, the purchase of lightly burned powder produced in Liaoning also increases the cost of freight

Abstract

The invention relates to an ultra-thin stone phenolic foam composite board, which relates to a thermal insulation board for external wall insulation composed of various materials. The purpose is to provide an ultra-thin stone phenolic foam composite board with good thermal insulation performance, good fireproof performance, reducing phenolic foam plastic powdering, and using lightly burnt powder produced in Laizhou, Shandong. The ultra-thin stone phenolic foam composite board of the present invention comprises a stone layer, a B-grade phenolic foam plastic layer, a glass magnesium fireproof board layer, and an adhesive layer; wherein the two connection surfaces of the B-grade phenolic foam plastic layer are respectively connected to the stone layer through the adhesive layer , The glass magnesium fireproof board layers are closely connected; wherein the two outer sides of the glass magnesium fireproof board are non-woven fabric layers, the middle is a slurry layer, and a glass fiber cloth layer is arranged between the non-woven fabric and the slurry layer; the slurry The layer comprises the following components in parts by mass: 100 parts of lightly burned powder, 65-75 parts of halogen flakes, 35-45 parts of sawdust, 10-15 parts of perlite and 2-3 parts of talcum powder.

Description

technical field [0001] The invention relates to a thermal insulation board for external wall insulation, in particular to a thermal insulation board for external wall thermal insulation composed of multiple materials. Background technique [0002] In the existing external wall insulation system, heat insulation materials such as polystyrene foam board (also known as EPS board), extruded polystyrene foam board for heat insulation (also known as XPS board), sprayed polyurethane, and polyurethane foam board are mainly used. These systems have certain safety hazards and poor fire performance, which limits their application. [0003] Phenolic foam plastic is a new type of fire-resistant, fire-proof and low-smoke insulation material. Its most prominent features are flame-retardant, low-smoke, and high-temperature disparity resistance. restricted. [0004] Glass magnesium fireproof board is a new type of non-combustible material, which has superior strength, heat insulation and e...
