Basalt fiber reinforced sea sand cement-base composite heat insulation wall plate

Abstract

The invention relates to the field of building materials, and provides a basalt fiber reinforced sea sand cement-base composite heat insulation wall plate and a preparing method of the basalt fiber reinforced sea sand cement-base composite heat insulation wall plate. The basalt fiber reinforced sea sand cement-base composite heat insulation wall plate is a novel composite heat preservation wall plate formed by using basalt fiber bar reinforced sea sand cement-base rib beams and basalt fiber mesh reinforced sea sand cement-base thin plates as major stress components, using heat preservation and insulation plates as embedded plates and using gypsum decoration plates as inner panels through compounding. The wall plate has the characteristics that the weight is light; certain pressure-resistant capability and shear-resistant capability are realized; the durability is high; and the waterproof and heat preservation and insulation performance is good, and the like. The basalt fiber reinforced sea sand cement-base composite heat insulation wall plate is suitable to be used as a building external wall plate, particularly for external walls of a coastal building.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a sea-sand cement-based composite thermal insulation wallboard reinforced by a novel basalt fiber material and a preparation method thereof. Background technique [0002] In recent years, with the country's emphasis on building energy conservation and environmental protection, localities have increased the intensity of banning or restricting the use of solid clay bricks. The production and utilization of new wall panels, especially lightweight composite wall panels, have gradually attracted people's attention. After a long period of development and promotion, the utilization rate of lightweight wallboard materials in my country's construction is still very low. In 2012, the utilization rate of lightweight wallboard materials was only 8%. This is mainly because the current wall panels, especially the composite thermal insulation wall panels for external walls, often have problems ...

AI Technical Summary

Problems solved by technology

[0002] In recent years, with the country's emphasis on building energy conservation and environmental protection, localities have increased the intensity of banning or restricting the use of solid clay bricks. The production and utilization of new wall panels, especially lightweight composite wall panels, have gradually attracted people's attention. After a long period of development and promotion, the utilization rate of lightweight wallboard materials in my country's construction is still very low. In 2012, the utilization rate of lightweight wallboard materials was only 8%.

This is mainly because the current wall panels, especially the composite thermal insulation wall panels for external walls, often have problems such as large thickness and low strength, which cannot well meet the requirements of engineering use.

[0003] In addition, the current development of new wall panels is mainly focused on the improvement of thermal insulation materials, without considering the overall durability of wall panels, especially the wall panels used in coastal areas, due to the use of traditional steel reinforcement, after a certain number of years of use, Steel tends to corrode, greatly reducing its strength and safety
