Abstract

The invention discloses a composite insulation board and a production method thereof. The composite insulation board is formed by compositing a calcium silicate panel, glass fiber gridding cloth and lightweight concrete. The production method of the composite insulation board comprises steps as follows: the alkali-resistant glass fiber gridding cloth is fixed on an inner parathion of a vertical mold, and the calcium silicate panel with bonding holes leans in the mold; fly ash, polyphenyl foam particles, low-alkalinity sulphoaluminate cement, polyvinyl acetate glue powder, polyvinyl alcohol reinforced fibers with high modulus of elasticity, a sodium methylsilanolate water repellent, an efficient polycarboxylic acid water reducer and water are sequentially added to a stirrer in proportion and evenly stirred to form slurry; the slurry is pumped into a vertical mold through a high-pressure slurry pump; the slurry is demolded after curing and hardening and subjected to film winding, packaging and curing. The composite insulation board is high in strength and good in thermal insulation and fire prevention; the production method is simple and easy to implement due to adoption of ingredient stirring and pouring molding by the vertical mold. During usage, the construction technology is simple, the speed is high, time and labor are saved, and the economic benefit is significant.

Description

technical field [0001] The invention relates to a building material and a production method thereof, in particular to a composite thermal insulation board and a production method thereof. Background technique [0002] At present, with the improvement of people's living standards, the functional requirements for buildings such as earthquake resistance and disaster reduction, energy saving and heat preservation are also increasing. At the same time, high-rise buildings are widely designed and constructed, and the application of reinforced concrete shear wall structures in buildings is developing rapidly. In order to solve the problem of energy saving and thermal insulation of shear walls and frame beams and columns, save energy and material resources, enhance the durability of buildings and facilitate construction, it is urgent to develop materials that integrate thermal insulation, energy saving and building structure. At present, although the existing organic foam insulation...
