Embodiment 1

[0093] The following will refer to the attached Figure 5 The manufacturing process of the water-resistant board as the building decoration board is described in detail. figure 1 The direction of the process flow of the present invention is shown with reference numeral 16 .

[0094] The main raw material powder ash for making water-resistant board is composed of desulfurized gypsum, slag powder and cement. The filling amount of gypsum is relatively large, mainly because of the quick-setting characteristics of gypsum and the low drying shrinkage value of the finished product. The drying shrinkage value is The most critical technical data index required by the prefabricated building structure determines the main factor of whether the appearance of the prefabricated building structure is cracked. At present, only gypsum has a low dry shrinkage value among the known building cementitious materials, so the main The material is gypsum, and in order to maintain a low dry shrinkage v...

Embodiment 2

[0182] The difference from Example 1 is that the raw material additives for making water-resistant boards also include PVA (polyvinyl alcohol). After a large number of experiments, the comparison results of water-resistant board experiments shown in Table 1 are obtained.

[0183] Comparison results of water-resistant board experiments

[0184] Table 1. Test sample block: 250×250×17

[0185]

[0186] Note: the powder ash in the table is 1 part

[0187] According to the above table 1, the optimal ratio of raw materials for water-resistant boards is: fly ash + 70% water + 5% saw foam + 1.4% PVA + upper and lower glass fibers, flexural strength 10-12, bulk density 1050-1100, initial setting time 8-10min, high flexural strength, short initial setting time, and less cost increase.

Embodiment 3

[0189] The difference from Example 1 is that the additives used in making the water-resistant board include PVA (polyvinyl alcohol) and waterproofing agent. After a large number of experiments, the comparison results of the water-resistant board experiments shown in Table 2 are obtained.

[0190] Table 2. Comparison of water absorption in different proportions

[0191]

[0192] Note: the powder ash in the table is 1 part

[0193] It can be known from the above table 2 that in terms of the water resistance of the water-resistant board, the best ratio of raw materials for the water-resistant board is: powder ash + 70% water + 5% saw foam + 1.4% PVA + 3% waterproofing agent, after soaking in water for 1 Hours, the water absorption rate is only 10-15%, and it will not have a good decorative effect of efflorescence.

Abstract

The invention relates to a production line and method for manufacturing a building decorative sheet. The production line comprises a production forming area, a maintenance area and a drying area, wherein the three areas are arranged in a sealed space capable of collecting sunlight and are mutually communicated, the steps of production formation, maintenance and drying of the sheet can be finished in the same sealed space, solar energy is fully utilized, the heat efficiency is improved by 65%-85%, and energy is saved. According to the method for manufacturing the building decorative sheet, the sheet is formed through a conveying belt, glass fibers cover the two surfaces of the sheet, the forming method is simple and rapid, and the compressive strength and flexural strength of the manufactured sheet are high. In addition, the production line is suitable for air hardening sheets, hydraulicity sheets and sheets with both air hardening performance and hydraulicity.

Description

technical field [0001] The invention relates to a production line for making building decoration boards and a method for making building decoration boards using the production line, belonging to the technical field of building materials. Background technique [0002] With the needs of urban construction and environmental protection, at present, formwork is required for pouring concrete structures, which consumes resources and pollutes the environment. With the continuous improvement of our country's living standards, labor costs have also increased. Finding a new wall structure that is convenient, fast and environmentally friendly is a key technology that needs to be solved urgently today. As for the panels of assembled walls, when water resistance and waterproof are required, most of them are solved by coating paint. The Chinese patent No. 92109412.4 discloses a multi-functional sandwich panel, which is composed of foam plastic, glass fiber cloth and decorative materials. ...
