Polyurethane hard bubble sandwiched integral heat preservation light wall board and method for making same

Abstract

A polyurethane hard bubble interlayer integrated heat preservation lightweight wall board is characterized in that casting a polyurethane hard bubble interlayer between two concrete lightweight wall boards. The preparation process comprises installing the concrete lightweight wall board which is prepared according to the conventional method, guaranteeing the distance of the interlayer, casting the polyurethane hard bubble for the interlayer, and finally stabilizing solidification and conducting reasonable curing. The polyurethane hard bubble interlayer integrated heat preservation lightweightwall board which is prepared by the process of the invention has vibration-damping and sound insulation, fire resistant and resistant to flame, heat preservation and waterproof, excellent heat insulation, lightweight wall board, high specific tenacity and compact and firm structure and strong suitability for main structure, and the service life of the invention can reach 30 years under the normalweather temperature conditions. And the invention has fast construction speed, high efficiency and excellent environment-friendly property, and the finished product has prices advantage, which is really an energy-saving emission reduction environment-friendly product.

Description

technical field [0001] The invention relates to a polyurethane rigid foam sandwich integrated thermal insulation lightweight wallboard and a preparation method thereof. Background technique [0002] With the progress of the times, sustainable and coordinated development has been put on the agenda, building energy conservation has become an essential measure, and external wall insulation is one of the most effective means of building energy conservation, so it has attracted much attention. [0003] The thermal insulation function of the wallboard is realized by setting the thermal insulation layer in the wallboard structure. Existing wall panels of this type have metal panels or concrete or wood panels as surface materials, and materials such as perlite or polystyrene foam or foamed resin are sandwiched inside, and sandwich panels are also produced, but these products generally have thermal insulation performance. Not good enough, the energy-saving effect is not ideal, some ...

AI Technical Summary

Problems solved by technology

Existing wall panels of this type have metal panels or concrete or wood panels as surface materials, and materials such as perlite or polystyrene foam or foamed resin are sandwiched inside, and sandwich panels are also produced, but these products generally have thermal insulation performance. Not good enough, the energy-saving effect is not ideal, some are difficult to resist cold and heat, thermal insulation and moisture-proof, sound insulation performance is poor; , but the manufacturing cost is high, it cannot be formed at one time, there are many processes, and the strength, bending and compression resistance, and fire and waterproof performance of the wallboard are not stable enough, resulting in relatively high costs and construction problems in applying existing thermal insulation building materials to building energy-saving projects. Defects such as complicated process, technical parameter requirements and insufficient thermal insulation and moisture-proof performance
