Embodiment 1
[0023] One, such as figure 1 As shown, this embodiment provides a decorative gypsum floor and a decorative gypsum board, both of which include a colored patterned gypsum block 1 and a main gypsum layer 2, the main gypsum layer 2 is wrapped around the colored patterned gypsum block 1, and the colored patterned gypsum layer 2 The patterned gypsum block 1 is integrally connected with the main gypsum layer 2 .
[0024] Two, the preparation method of described decorative gypsum floor and decorative gypsum board, comprises the steps:
[0025] Step 1, preparation of colored pattern gypsum block: design the pattern gypsum layer manufacturing mold according to the desired pattern pattern ( figure 1 The pattern in the pattern can also be designed into other various required hollow patterns), the colored gypsum color paste is poured into the patterned gypsum layer to make a mold, and the colored patterned gypsum block is obtained after being completely dry (usually greater than or equal...
Embodiment 2
[0033] The colored gypsum color paste in step 1 in this embodiment includes 95 parts of α-gypsum powder, 4 parts of water-based color paste, 0.5 part of dispersant, 0.5 part of sodium citrate, and 0.5 part of water reducing agent in parts by weight.
[0034] The main gypsum casting material described in step 2 includes 85 parts of alpha gypsum powder, 4 parts of water-based color paste, 0.5 part of dispersant, 0.5 part of retarder, 0.5 part of water reducer and 10 parts of white marble powder in parts by weight.
[0035] All the other steps are the same as in Example 1.
Embodiment 3
[0037] The colored gypsum color paste in step 1 in this embodiment includes 80 parts of α-gypsum powder, 10 parts of water-based color paste, 1 part of dispersant, 1 part of sodium citrate, and 2 parts of water reducing agent in parts by weight.
[0038] The main gypsum casting material described in step 2 includes 60 parts of α-gypsum, 10 parts of water-based color paste, 1 part of dispersant, 1 part of retarder, 2 parts of water reducing agent and 40 parts of sandstone powder in parts by weight; Step is with embodiment 1.

Abstract
The invention discloses a decorative gypsum terrace and a decorative gypsum board and a preparation method thereof. The method comprises the following steps of (1) designing a pattern gypsum layer manufacturing mold according to the required pattern, casting the colorful gypsum slurry into the pattern gypsum layer manufacturing mold, and drying to obtain a colorful pattern gypsum block; (2) putting the colorful pattern gypsum block obtained in the step 1 into a ground or a plate mold, casting a main gypsum casting material into the ground or the plate mold, solidifying to form a main gypsum layer, so as to obtain a decorative gypsum terrace or a decorative gypsum board crude product; and (3) after standing for 2-6 hours at room temperature, carrying out water grinding, so that washing themain gypsum casting material covered on the colorful pattern gypsum block away by water; or standing until the main gypsum casting material is completely dried, grinding into powder through a grindingmachine, and blowing or sucking the powder to remove the powder. The main gypsum layer and the colorful pattern gypsum block in the decorative gypsum terrace or the decorative gypsum board are integrated, and the phenomenon of layering is avoided.
Description
technical field [0001] The invention relates to the technical field of gypsum products, in particular to a decorative gypsum floor, a decorative gypsum board and a preparation method thereof. Background technique [0002] Gypsum is a widely used industrial material and construction material, which can be used in gypsum building products, cement retarder, model making, medical food additive, sulfuric acid production, paper filler, paint filler, etc. In recent years, gypsum materials and gypsum products have been widely used in interior decoration and decoration of buildings, especially in the decoration and decoration of family houses. Compared with other similar materials, gypsum products have the characteristics of relatively light texture, high strength, and good fire resistance. One of the first choice materials for decoration. Yet existing gypsum boards are all white, without patterns and colors, and their strength needs to be improved as a base plate or a decorative w...
