A method for manufacturing compression-resistant, warpage-resistant, water-repellent, flame-retardant thermal insulation foam material

Abstract

The invention relates to a method for manufacturing a pressure-proof, warping-resistant, hydrophobic, flame-resistant and thermal-insulated foam material. The method includes using phenolic resin, silica sol, EPS foam or the modified EPS foam bead and glass wool short fiber or mineral wool short fiber as base materials; preparing a total adjusting liquid from the phenolic resin uniformly mixed by various auxiliary agents such as foaming agent, surface conditioning agent of glass wool or mineral wool fiber, surface active agent, fire retardant, flexibilizer, penetrating agent and modified filler in a ratio; mixing EPS foam or the modified EPS foam bead, glass wool short fiber or mineral wool short fiber, and curing agent uniformly, and foam molding an enhanced hard composite foam material. The product prepared by the method is an environmental-friendly novel thermal insulation material with good flame-retardant efficiency and reasonable price. The requirements of construction of thermal insulation in building and safety and fire prevention are met, and the construction time and cost are saved effectively.

Description

technical field [0001] The invention belongs to the field of building construction technology, thermal insulation technology and materials, in particular to a method for manufacturing compression-resistant, warpage-resistant, water-repellent and flame-retardant thermal insulation foam materials. Background technique [0002] At present, with the continuous development of urbanization in the country, there are many high-rise buildings everywhere. People pursue the comfort of indoor and outdoor environments in residential buildings. As a very important part of energy conservation, building energy conservation has attracted extensive attention from the state and society. Among them, the energy saving of envelope structure accounts for 30% to 40% of building energy saving. With the characteristics of polystyrene foam (EPS) and polyurethane foam (PU) wall insulation materials due to their low thermal conductivity, small water absorption performance, good electrical insulation per...

Problems solved by technology

It is used in low temperature or even ultra-low temperature environment with small shrinkage and no embrittlement. It is an ideal heat insulation material for cryogenic engineering, so it is widely used in hotels, hospitals, high-rise buildings, subways, airports and other central air-conditioning systems for heat preservation; it is also suitable for petroleum and chemical industries. Insulation and heat preservation of pipelines and equipment in fields such as power industry and electric power industry; but the mechanical properties of PF foam plastic itself are poor, especially brittleness and easy pulverization, this defect greatly limits its application, especially as a thermal insulation material for building exterior walls Insulation materials are widely used, so that the external wall insulation must wait for the main body of the building to be completed, and the construction is completed by the process of veneering, which is time-consuming and labor-intensive. Moreover, when the difference in external room temperature changes greatly, the insulation board is prone to warping, causing the insulation layer to crack. In severe cases, the surface layer of the outer wall will fall
