Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a desulfurized gypsum high-strength crystal decorative board for the deficiencies in the prior art, which solves the problem of condensation on the desulfurized gypsum powder by pre-transforming and activating the microscopic structure. Problems of fast time, unstable strength, high expansion rate, and high particle density; and by compounding with ambient photocatalytic mineral powder processed from ambient photocatalytic waste, a desulfurized gypsum high-strength crystal decorative board is obtained, which has the ability to purify formaldehyde, negative Oxygen ion induction, self-humidity adjustment and other ecological properties realize the "ecological" utilization of industrial waste residue resources

Embodiment 1

[0048] A desulfurized gypsum high-strength crystal decorative board, the flow chart is as follows figure 1 As shown, it is prepared by the following method:

[0049] (1) Preparation of desulfurized gypsum activated micropowder:

[0050] ①Ball mill crystal conversion activation: 99.36 parts of ordinary β-desulfurized gypsum cooked powder, 0.3 parts of dispersible latex powder, 0.02 parts of potassium aluminum sulfate, 0.02 parts of sodium citrate, 0.2 parts of sodium pyrophosphate, hydroxypropyl methylcellulose ( After 0.1 part of HPMC) is mixed evenly, it is added to the ball mill for ball milling to activate the crystal transformation, and the material enters into two storage tanks after ball milling for about 50 minutes;

[0051] ② Homogenization and aging: The materials prepared in the two storage tanks in step ① are discharged at the same time, and are homogenized by a screw conveyor and then transported to a moisture-proof package, and naturally aged for about 10 days to...

Embodiment 2

[0068] A desulfurized gypsum high-strength crystal decorative board is prepared by the following method:

[0069] (1) Preparation of desulfurized gypsum activated micropowder:

[0070] ①Ball mill crystal conversion activation: 95.75 parts of ordinary β-desulfurized gypsum cooked powder, 1.2 parts of vegetable gum powder, 0.02 parts of sodium citrate, 0.03 parts of calcium chloride, 0.2 parts of sodium pyrophosphate, 0.3 parts of trisodium citrate, hydroxypropyl After mixing 0.5 parts of HPMC and 2.0 parts of pregelatinized starch evenly, add them to the ball mill for ball milling to activate the crystal transformation, and the materials are ball milled for 50-55 minutes and then enter into two storage tanks;

[0071] ② Homogenization and aging: The materials prepared in the two storage tanks in step ① are discharged at the same time, and are homogenized by a screw conveyor and then transported into a moisture-proof package, and naturally aged for 12 days to obtain stable perfo...

Abstract

The invention discloses a flue gas desulfurization gypsum high-strength crystal decorative sheet and its manufacturing method. the method comprises the following steps: mixing flue gas desulfurization gypsum prepared powder, rubber powder, a crystal modifier, a swelling reducer and a water-retaining agent according to the weight ratio of 95-99.6: 0.1-1.2: 0.02-0.05: 0.2-1.0: 0.1-2.8 so as to prepare flue gas desulfurization gypsum activated micro-powder; stirring the flue gas desulfurization gypsum activated micro-powder, photocatalysis environmental mineral wastes, a waterproof agent, a complex glue solution and reinforced fiber / gridding cloth according to the weight ratio of 100: 0.5-12: 0.1-1.8: 60-75: 0.8-7.0, vibrating, carrying out secondary stirring, carrying out double-face locating and film-mulching forming, demoulding, cutting and polishing, drying and maintaining, and processing by a facing treatment so as to obtain the decorative sheet. The problems of fast coagulation time, unstable strength, high swelling rate and large particle density existing in the prior art are solved. The prepared decorative sheet has formaldehyde-purifying, negative oxygen ion induction and self-humidity-control ecological features. Resource ecological utilization of industrial wastes is realized, full-automatic standard production is achieved, and standardized control of appearance quality and performance of the product is realized.

Description

technical field [0001] The invention relates to a high-strength crystal decorative board and a preparation method thereof, in particular to a desulfurized gypsum high-strength crystal decorative board and a preparation method thereof, in particular to a desulfurized gypsum high-strength crystal decorative board containing desulfurized gypsum activated micropowder and a preparation method thereof. The method utilizes solid waste resources to prepare ecological building materials. Background technique [0002] "Energy saving and emission reduction, circular economy, sustainable development, and green building materials" are common topics in the new normal and new development approaches. With the implementation of the gas desulfurization plan, its output will continue to rise with the continuous construction of flue gas desulfurization devices. Xu Luoyi, director of the Building Materials Industry Technology Information Research Institute, pointed out in the 2014 discussion fo...
