Fire-resistant lightweight particles and polyurethane filled wall panel and production method

Abstract

The invention discloses a fire-resistant lightweight particles and polyurethane filled wall panel. The wall panel comprises support frames, a first edge, a second edge, a wall panel and a heat-insulating layer; two support frames are parallelly arranged up and down as a top surface and a base surface of the wall panel; two ends of the first edge and the second edge are fixed at two ends of the two support frames as two connecting surfaces of the wall panel; adjacent wall panels are spliced through the first edge and the second edge and a fold line sound insulation and heat insulation path is formed; the support frames, the first edge and the second edge are spliced to form a wall panel skeleton; the wall panel boards are installed at two sides of the wall panel skeleton and are spliced to form a hollow structure; fire-resistant lightweight particles and polyurethane are used as heat insulation material which the hollow structure is filled with. The invention also discloses a method for producing the above wall panel, comprising following steps: splicing a square box structure, spraying and filling and mounting reserved panels. The invention relates to the field of buildings. The invention provides a reused wall panel which has good heat insulation and sound insulation and high fire-resistance and production method.

Description

technical field [0001] The invention relates to the field of construction, in particular to a wallboard filled with refractory lightweight granular polyurethane foam material and a production method. Background technique [0002] Standardization and industrialization are one of the most important links in the development of affordable housing. Taking the lead in realizing standardized design, industrialized production, assembled construction, and information management in the construction of affordable housing is not only an important means to achieve the requirements of improving the quality of affordable housing, shortening the construction period, and controlling costs, but also the core of accelerating the upgrading of the housing industry in my country. important way. [0003] Traditional house buildings, especially those with metal structure and integral poured cement structure, are empty inside except for the structural load-bearing columns. According to the needs of ...

Problems solved by technology

These technical solutions are difficult to implement embedded metal sheets or metal profiles for adding heavy objects, and it is also difficult to achieve the overall sealing of the wall and the combination of sealing between the walls. There are gaps for breathability and water permeability

[0004] In addition, other inorganic foam plates such as rock wool felt, rock wool plate, foamed perlite plate, foamed ceramic plate, foamed glass plate, etc. The layer is generally small, and a wall may be 2.5 meters to 5 meters high. The bonding between the middle insulation layer and the wall panels on both sides requires a large amount of adhesive, which increases the weight and greatly increases the cost, and the rock wool felt itself has no The strength needs to be fixed with rock wool nails and a lot of adhesive

The application of a large number of walls with organic insulation materials such as polystyrene boards, polyurethane boards, foam fillings, and phenolic foam boards as intermediate insulation materials is limited due to low fire resistance. Walls made of coal ash, etc., need to be cured for a long time to set the shape, and the weight is greatly increased, which is inconvenient for on-site construction
