Fiberglas reinforced plaster tablet and method for making the same

Abstract

The invention relates to a building material as well as the manufacturing method thereof, in particular to a glass fiber reinforced gypsum board as well as the manufacturing method thereof. The glass fiber reinforced gypsum board comprises the components by weight parts as follows: 100 parts of high strength gypsum powder, 5 or more than 5 parts of glass fiber choppedstrand mat and glass fiber lattice cloth, (0.2 to 0.5) percent of water reducing agent, (0.1 to 0.5) percent of retarder and 30 to 33 parts of water. The manufacturing method comprises the following steps in sequence: batching, slurry-mixing, mould-entering and casting, finished-product knockout, dehydration and drying as well as shaping and cleaning. The glass fiber reinforced gypsum board has the advantages that the distortion is small, the dry / wet shrinkage rate is low, the strength is high, the weight is light, no odor exists, the board can be degraded for regeneration and utilization, the acoustic effect is good, the material surface is fine and clean, the reinforced gypsum board also has fireproof performance, and meanwhile, the manufacturing process is simple, the construction period is short, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a building material and a manufacturing method thereof, in particular to a glass fiber reinforced gypsum board and a manufacturing method thereof. Background technique [0002] In the known technology, with the rapid development of the economy and the improvement of people's living standards, people's demand for high-end cultural entertainment exchange places is increasing day by day, and various large-scale landmark buildings have emerged at the historic moment. These buildings have unique appearances and interior decorations. It is full of changes, and it is required to provide new edge-colored building materials with fine appearance, gorgeous appearance, no deformation, light weight, high strength, fire prevention, environmental protection and easy installation. Chinese Patent Publication No. CN1174822A, the publication date was March 4, 1998. The name of the invention is "a new type of high-strength fiber gypsum board". Ca...

Problems solved by technology

Chinese Patent Publication No. CN1174822A, the publication date was March 4, 1998. The name of the invention is "a new type of high-strength fiber gypsum board". Calcium sulfate water ≤ 75% blue paste and fly ash and slag powder, expanded perlite, hydroxide, glass short fiber, plastic material, water and glass fiber mesh cloth, the disadvantages are appearance color difference, The strength is not good, the ratio of ingredients is too high, and the manufacturing quality is not easy to control

Another example: Chinese Patent Publication No. CN1380267A, published on November 20, 2002, the name of the invention is "glass fiber reinforced gypsum board and its manufacturing method", the application discloses the proportion of glass fiber reinforced gypsum board, its It is composed of hemihydrate gypsum powder, white cement, talcum powder, expanded perlite, chemical agents, short glass fiber filaments, long glass fiber filaments, glass fiber mesh cloth, water, etc. The disadvantage is that although the performance has been improved, However, there are also disadvantages such as complex proportioning, difficulty in mixing long and short glass fiber filaments, cumbersome manufacturing process, difficult quality control, and still cannot meet the needs of gypsum boards today.
