Embodiment 1

[0027] Embodiment 1: glass fiber reinforced gypsum board, its composition and content are respectively: high-strength gypsum powder: 100, the mixing amount of glass fiber short chip mat and glass fiber mesh cloth is 5.0, the mixing amount of water reducer is 0.3 %, the blending amount of the retarder is 0.1%, and the water is fresh water that does not contain oil, hydrochloric acid or organic matter in accordance with the national standard, and its content is 30%.

[0028] The high-strength gypsum powder is an improved α-type calcium sulfate hemihydrate gypsum, which is produced by hydrothermal decomposition. Its crystal characteristics are hexagonal short columns, which is the basis for obtaining ultra-high-strength gypsum. It has a lower standard consistency water demand and High strength, non-flammable properties, neutral (ph value) or weakly alkaline, and its purity is not less than 90% by weight of dihydrate gypsum.

Embodiment 2

[0045] Embodiment 2: glass fiber reinforced gypsum board, its composition and content are respectively: high-strength gypsum powder: 100, the mixing amount of glass fiber short chip mat and glass fiber mesh cloth is 5.8, the mixing amount of water reducing agent is 0.4 %, the blending amount of the retarder is 0.2%, and the water is fresh water that does not contain oil, hydrochloric acid or organic matter in accordance with the national standard, and its content is 33%.

[0046] The high-strength gypsum powder still uses improved α-type calcium sulfate hemihydrate gypsum, the water reducer uses HSM high-sulfonated melamine high-efficiency water reducer, and the retarder adopts XB-SG-11 type gypsum retarder Agent, construction steps follow the method of embodiment 1. Various technical indicators of glass fiber reinforced gypsum board are within the standard range.

[0047]The glass fiber reinforced gypsum board produced by the present invention can be made by adding different...

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...
