Embodiment Construction

[0027] Insulated roof panels are made by:

[0028] (1) Ingredients

[0029] High-strength α-type gypsum: 26 parts, calcium phosphate cement: 13 parts, fly ash: 31 parts, rosin soap foaming agent: 2.5 parts, 107 glue: 0.25 parts, glass fiber: 2.5 parts, water: 24.75 parts.

[0030] The role of raw materials is as follows:

[0031] High-strength α-type gypsum: High-strength α-type gypsum is hemihydrate gypsum, which has strong hydration properties. After it is mixed with water, firstly, high-strength α-type gypsum dissolves in the aqueous solution to form a metastable saturated solution, dihydrate gypsum Soon crystallize in saturated solution, and the crystallization of dihydrate gypsum destroys the original equilibrium state of hemihydrate gypsum, which will promote its further dissolution until all the crystallization is dihydrate gypsum to generate strength.

[0032] Calcium phosphate cement: The compressive strength of the roof slab increases with the increase of the perce...

Abstract

The invention discloses a thermal insulation roof panel, which is characterized by comprising: 24-27 parts of high-strength alpha type gypsum, 12-14 parts of calcium phosphate cement, 30-33 parts of fly ash, 2.5 parts of a rosin soap foaming agent, 0.25 part of 107 glue, 2.5 parts of glass fiber, and 22-26 parts of water. The making steps include: (1) material compounding; (2) stirring; (3) compression atomization: loading the mixed solution into an extrusion pump, and performing compression atomization on the mixed solution by the extrusion pump; (4) injection: cutting the glass fiber to certain length by a cutting injection machine, jetting the glass fiber by airflow, then mixing the glass fiber with the atomization mixed solution in space and injecting the mixture to a die to form a product bottom layer and a surface layer, thus making the glass fiber and the substrate reach ideal two-dimensional disordered distribution; (5) pipe insertion; (6) vacuum dewatering; (7) pipe drawing; (8) steam curing; (9) die release; and (10) milling grinding. The thermal insulation panel made by the invention has high strength and low density.

Description

technical field [0001] The invention relates to a thermal insulation roof panel, in particular to a manufacturing method of the thermal insulation roof panel. Background technique [0002] Insulation roof panels are suitable for adding floors to light steel structures, frame structures, brick-concrete structures, light-weight plate-type quick-installed residences, high-rise steel structures and other buildings. The lateral rigidity of the thermal insulation roof panel is large, which can change the roof support from the rigid support of the color steel plate roof to the flexible support, thereby reducing the amount of steel used in the support system. However, the strength and thermal insulation properties of the existing thermal insulation roof panels are difficult to meet the predetermined requirements, which limits the scope of application of the thermal insulation roof panels. Contents of the invention [0003] The technical problem to be solved by the present inventi...
