Problems solved by technology

However, this method requires temporary slotting according to the size of the connector before installation, so there are more slotting processes and it is not easy to install
At the same time, to open a wider slot in the cement board, only when the thickness of the cement board is sufficient can the slotting be successful and effective, which will result in a thicker cement board, making the insulation board very heavy and increasing the The weight burden of its connection with the wall, the stability of the connection is also affected

Embodiment 1

[0097]The preparation method of the thermal insulation board of this embodiment is as follows:

[0098](1) According to mass percentage, mix 42.5R cement 34.5%, 0.01-5mm quartz sand 60.55%, Beijing microbeads 1%, polycarboxylic acid water reducing agent 1.5%, lithium carbonate 0.1%, sodium gluconate 0.05%, glass fiber (6mm, Taishan easy-dispersing glass fiber) 0.3% and 2.0% of the water-based polyacrylate emulsion are mixed with water together to control the water-binder ratio to 0.25. At this time, the glue-sand ratio is also within the preset range, and the mixture is evenly stirred to make the initial automatic flow The degree of fluidity is 234mm cement slurry.

[0099](2) Build the mold. Place the mold frame (the inner dimension of the mold frame is 450mm*300mm*40mm) on the surface of the plate. Before injection molding, a layer of nano silica emulsion with a concentration of 10% was applied to the inner wall of the mold frame and the surface of the plate.

[0100](3) Inject a layer of ...

Abstract

The invention relates to an integrated insulation board with a built-in connecting piece. The integrated insulation board comprises a cement shell and a heat insulation core material. The cement shellis a flat hexahedron, a filling space of the heat insulation core material is formed in the hexahedron, and the connecting piece is further arranged in the filling space. The cement shell is formed by cement paste through injection molding and curing, and the cement paste comprises the following components in percentage by mass: 20-60% of cement, 30-70% of quartz sand, 0.1-10% of microbeads, 0.01-2% of a water reducing agent, 0.01-2% of lithium carbonate, 0.01-2% of sodium gluconate, 0.01-2% of glass fibers and 0.1-6% of a low-temperature water-based emulsion; the components are mixed with water to obtain the cement paste, the water-binder ratio of the cement paste is 0.25-0.5, and the binder-sand ratio of the cement paste is 0.25-0.7. The shell adopts an innovative cement paste formula,and enough breaking strength and compressive strength can be provided under the condition of extremely small thickness after curing. According to the invention, the installation of the insulation board can be simplified, and the insulation board with lighter specific gravity and better thermal insulation performance can be obtained; the hexahedral cement shell blocks environmental factors, plays arole in protecting the thermal insulation material, prolongs the service life of the thermal insulation material and provides fireproof and flame-retardant effects.

Description

Technical field[0001]The invention relates to the technical field of inorganic building boards, in particular to an integrated thermal insulation board with built-in connectors and a preparation method thereof.Background technique[0002]At present, the insulation boards used in the market are divided into inorganic insulation boards and organic insulation boards. Organic insulation boards have better insulation performance, light specific gravity, and easy production. However, compared with inorganic insulation boards, organic insulation boards have poor stability and resistance. Poor flammability, not resistant to aging and easy to deform; inorganic insulation board contains perlite, diatomaceous earth, rock wool, foam glass, slag wool or foamed cement board, etc., and has good fire resistance, but the insulation is worse than organic insulation board, which is easy Chalking, high specificity, not easy to adhere to the outer wall of the building or easy to fall off after installatio...
