Description
Technical Field
The invention relates to a composite heat-insulation gypsum board and a preparation method thereof, belonging to the technical field of artificial boards.
Background
With the rapid development of the economy in China, the demand of the building decoration industry for the gypsum plaster boards is on the trend of increasing year by year, according to the statistics in 2020, the usage amount of the gypsum plaster boards in China reaches nearly 34 hundred million square meters, and from the aspect of product application, the ratio of the gypsum plaster boards used for ceiling decoration exceeds 70 percent, the gypsum plaster boards used for partition wall systems is only less than 30 percent, and the domestic partition wall materials are still mainly made of traditional materials such as clay bricks. Against the market of developed countries in Europe and America, the gypsum board is used in the field of building partition walls, accounts for about 80 percent and is used for ceiling decoration and finishing less than 20 percent. Compared with Europe and America, the permeability of the gypsum board in the partition wall market still has great promotion space.
In order to ensure the heat-insulating property of the wall body in the process of manufacturing the partition wall, on one hand, a hollow wall body is made, polystyrene foam plastics are filled in the hollow wall body, and on the other hand, the traditional composite heat-insulating gypsum board is mostly used as a heat-insulating material, and the traditional composite heat-insulating gypsum board is mainly formed by directly sticking a molded or extruded polystyrene foam plastic board on the surface of a common paper-surface gypsum board through an adhesive to form an integrated heat-insulating material.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a composite heat-insulation gypsum board and a preparation method thereof.
A middle core layer of the composite heat-insulation gypsum board is wrapped by an upper protective paper, a lower protective paper, a left side surface sealing paper and a right side surface sealing paper respectively, the middle core layer contains gypsum and part of cement bonding materials, and the gypsum and the part of the cement bonding materials are filled with polyphenyl particles or expanded perlite and glass fiber.
A preparation method of a composite heat-insulation gypsum board comprises the following steps: adding gypsum powder and cement powder into a stirrer, wherein the mixture ratio is as follows:
80-100 parts of gypsum powder;
20-30 parts of cement powder;
and simultaneously adding water containing a water reducing agent and starch (55-60 parts of the water reducing agent and the starch), adding polyphenyl particles or perlite attached with a coupling agent coating, arranging the mixed slurry on upper-layer protective paper placed in the direction, pressing upper-layer protective paper, pressing a plate to form a certain thickness, cutting the finally-set plate, drying, and sealing edges to obtain the composite heat-preservation paper-surface gypsum board.
The invention has the advantages that:
(1) the thermal resistance Rs1 on hot side of the composite board is not more than 0.2 square meter K/W, and the thermal resistance Rs2 on cold side of the composite board is not more than 0.15 square meter K/W, which is obviously superior to the traditional composite board.
(2) The traditional composite heat-preservation gypsum board is not externally pasted with heat-preservation plastic, so that the integration of heat preservation and heat insulation is realized, and the problem that an externally pasted heat-preservation material falls off does not exist.
(3) The broken glass fiber is used as a reinforcing material, so that the requirement of the paper-surface gypsum board on the breaking strength is improved.
(4) In order to enhance the hardness of the core layer bonding material, a part of cement material is added, so that the strength of the plate core can be obviously enhanced.
