preparation example Construction

[0043] A method for preparing a fiber-reinforced polymer cement composite vacuum insulation board, characterized in that it comprises the following steps:

[0044] (1) After weighing the components of the mixed slurry, mix them thoroughly to obtain a mixture;

[0045] (2) After mixing the mixture obtained in step (1) with water, put it into the mixer and stir for 10 minutes to ensure sufficient mixing, wherein the mass ratio of water to the mixture of the above-mentioned components is 1: 2;

[0046] (3) Lay the sealing layer flat, then take a mold of the specified size and press it on it, and spread a layer of 1-20mm thick fiber-reinforced polymer cement mixed slurry, so that the mixed slurry can seal the inside of the mold. Layer covering, pressing for 8-24 hours, drying for 6-24 hours, and demoulding to form a high-strength gas barrier film with a protective layer;

[0047] (4) The high-strength gas barrier film with a protective layer is wrapped around the core material, a...

Abstract

The invention provides a fiber reinforced polymer cement and compound vacuum adiabatic insulation plate. The vacuum adiabatic insulation plate comprises core materials and high strength gas film resistance with protective layer. The high strength gas film resistance with protective layer is wrapped in the periphery of the core material and sealed by vacuum-pumping with the core materials; the high strength gas film resistance with protective layer is compound made of an outside protective layer and an inside sealing layer. The plate is characterized by excellent heat retaining property, safety, durability and light and thin, and it is convenient for the industrialization of the vacuum adiabatic insulation plate.

Description

technical field [0001] The invention relates to an external wall thermal insulation composite board in the field of construction, in particular to a reinforced polymer cement composite vacuum thermal insulation board added with a large amount of fibers and a preparation method thereof. Background technique [0002] Although the fire rating of the common vacuum insulation panels can meet the national standard for non-combustibility or flame retardancy, the thermal insulation effect is good. However, they are easy to be scratched during the construction process, hollowing and air leakage occur, and the utilization rate is greatly reduced. [0003] In the prior art, there are already vacuum insulation boards coated with low-alkali bonded mortar, foamed cement, inorganic thermal insulation mortar, and modified cement polyphenylene particles, and our company has applied for patents and obtained protection for the above technologies. However, the above-mentioned technology has pr...
