Embodiment

[0033] This embodiment includes the following steps:

[0034] (1) Prepare stirring solution

[0035] Use a measuring cup to measure 1200g of water, 108g of polyvinyl alcohol solution (solution mass concentration 8%), and 84g of 707 latex (solution mass concentration 40%). After mixing, add 2.4g of water reducing agent, 18g of water repellent, and 0.84g of retarder , defoamer 0.36g, stir well, obtain 1413.6g stirring solution;

[0036] (2) Preparation of mixed powder

[0037] Mix 2300g of gypsum powder and 92g of white cement evenly to obtain a mixed powder;

[0038] (3) Preparation of gypsum slurry

[0039] Pour the mixed powder obtained in step (2) into a bucket filled with the stirred solution obtained in step (1), add 34 g of chopped glass fibers while stirring, and stir for 30 seconds to obtain a gypsum slurry;

[0040] (4) Pouring molding

[0041] Pour 1 / 3 of the gypsum slurry obtained in step (3) into the PVC mold to make a base, touch it flat, cover the bottom, the...

Abstract

A high-crystal, light and high-strength gauge stuff ceiling is prepared through the following steps that firstly, a stirring solution is prepared, namely, a polyving akohol solution, the copolymer emulsion of polyvinyl acetate and ethylene, a water reducer, a water-proofing agent, a retarder and a defoaming agent are mixed with water and stirred evenly; secondly, mixed powder is prepared, namely gypsum powder and white cement are evenly mixed; thirdly, gypsum pulp is prepared, namely the mixed powder is poured in a barrel containing the stirring solution, short-cut glass fiber filaments are added during stirring, and even stirring is performed; fourthly, pouring molding is carried out, namely the gypsum pulp is poured in a PVC mold for bottoming, leveling and bottom shielding, and glass fiber gridding cloth and glass fiber bars are placed, wherein the glass fiber bars are placed close to the edge of an inner cavity of the PVC mold, residual pulp is poured in the PVC mold and ironed through a mud plate, a PVC cover plate is placed during knocking, and the periphery is compacted; and after the residual pulp is finally set, the high-crystal, light and high-strength gauge stuff ceiling is obtained through maintaining, drying and surface processing. The high-crystal, light and high-strength gauge stuff ceiling has the beneficial effects of being light in weight, low in transporting and installing cost, high in safety coefficient and the like.

Description

technical field [0001] The invention relates to a decorative gypsum ceiling, in particular to a high-crystal, light-weight and high-strength decorative gypsum ceiling. Background technique [0002] Decorative gypsum ceiling is a gypsum product with relatively mature production technology. The relevant industry standards and application technologies have been relatively perfect, so there are few breakthroughs in this field. [0003] At present, the quality of decorative gypsum ceilings on the market is about 10-12Kg / m 2 Between, and with the development of the housing construction industry, the floors are getting higher and higher, and the halls are getting bigger and bigger, which will inevitably put forward higher requirements for the load capacity of the house. Therefore, how to reduce the weight of decorative materials and ensure their strength is an urgent technical problem to be solved. Contents of the invention [0004] The technical problem to be solved by the pre...
