Problems solved by technology

[0003] In addition, there are all kinds of handicrafts in people's life, such as chess, pen holder, etc. Most of these handicrafts are made of wood, glass crystal, plastic or metal, while handicrafts made of building materials are rare.
In daily life, common handicrafts are generally made of plastic, wood, crystal or glass ceramics and other materials, and handicrafts made of plastic materials consume a lot of energy in the production process, and are difficult to degrade after being discarded, which can easily cause environmental pollution; The production of handicrafts made of materials will consume a lot of natural resources, which will lead to soil erosion, aggravate the greenhouse effect and other consequences, and affect the living environment of human beings; handicrafts made of crystal or glass ceramics have high production costs and high energy consumption. And easy to break, unable to balance aesthetics and practicality

Embodiment 1

[0035] Weigh the required components according to the parts by weight of the gypsum-based self-leveling material shown in Table 1.

[0036] The composition ratio of table 1 embodiment 1

[0037]

[0038] Mix the weighed solid components evenly and place them in the cement mortar mixing pot, then mix the weighed liquid components evenly and add them to the mixing pot where the solid components are placed, start the cement mortar mixer, and stir for 2 -4min to form a self-leveling slurry, and then pour the evenly stirred self-leveling slurry into the customized chess latex mold or other handicraft molds (such as pen holder molds, animation character model molds, etc.) three times, after each pouring Stir and tamp with a glass rod several times to remove the air bubbles attached to the inner wall of the mold as much as possible after pouring the slurry. After pouring, scrape off the excess slurry with a scraper and smooth it, and let it stand at room temperature for 24 hours. ...

Embodiment 2

[0042] Weigh the required components according to the parts by weight of the gypsum-based self-leveling material shown in Table 2.

[0043] The composition ratio of table 2 embodiment 2

[0044]

[0045] The steps of the rest of the manufacturing method are substantially the same as in Example 1.

[0046] For handicrafts such as chess made by using the formula of this example, the initial setting time of the self-leveling slurry material is 15 minutes, the final setting time is 38 minutes, the 7d dry compressive strength of the material can reach 13.2MPa, and the scratch hardness is 0.21mm. The wear resistance is about 13.7%, and the impermeability grade is P6. The handicrafts such as chess made have brighter color, better wear resistance, less surface burrs, and are not easy to drop powder.

Embodiment 3

[0048] Weigh the required components according to the parts by weight of the gypsum-based self-leveling material shown in Table 3.

[0049] The composition ratio of table 3 embodiment 3

[0050]

[0051] The steps of the rest of the manufacturing method are substantially the same as in Example 1.

[0052] For handicrafts such as chess made by using the formula of this example, the initial setting time of the self-leveling slurry material is 14 minutes, the final setting time is 35 minutes, the 7d dry compressive strength of the material can be as high as 15.7 MPa, and the scratch hardness is about 0.15 mm , the wear resistance is about 11.4%, and the impermeability level is P6. In addition, due to the large amount of cement, the handicrafts such as chess made are slightly darker in color than those in Example 1 and Example 2, but they have good wear resistance and are not easy to drop powder.

Abstract

The invention relates to a gypsum-based self-leveling material as well as an application and an application method thereof in artware. The gypsum-based self-leveling material is prepared from the following components in parts by weight: 90-110 parts of water, 141-159 parts of semi-hydrated gypsum, 110-125 parts of quartz sand, 10-25 parts of coarse whiting powder, 6-24 parts of general portland cement, 1-8 parts of latex powder, 0.3-0.9 parts of a water reducing agent, 0.1-0.5 parts of cellulose ether, 0.1-0.2 parts of a defoaming agent and 0.1-0.2 parts of a retarder. The gypsum-based self-leveling material can be used for manufacturing artware such as chess, pen containers, flowerpots and cartoon figure models, and the manufactured artware is smooth and fine in surface and not prone to powder falling. Compared with the prior art, the problems that a traditional gypsum-based material is poor in slurry liquidity, low in strength of a hardened finished product, large in number of surface air holes, prone to powder falling and the like are solved, and the prepared artware is smooth and mild in surface, glossy, high in strength and good in abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a gypsum-based self-leveling material and its application and application method in handicrafts. Background technique [0002] With the rapid development of the phosphate fertilizer industry, China has become the world's largest producer of phosphate fertilizer and phosphogypsum (the main component of phosphogypsum is dihydrate gypsum, and the molecular formula is CaSO 4 2H 2 O) By-product country. Phosphogypsum is a kind of industrial solid waste. Its arbitrary discharge not only occupies cultivated land, pollutes the environment, but also causes waste of resources. Therefore, the resource utilization of phosphogypsum has become a hot research topic for current researchers. [0003] In addition, there are all kinds of handicrafts in people's life, such as chess, pen holders, etc. Most of these handicrafts are made of wood, glass crystal, plastic or metal, while hand...
