Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sculpture products, in particular to a preparation method of anti-cracking sculpture products. BACKGROUND

[0002] As a kind of decoration, sculpture has its unique advantages compared with other works of art, such as stronger three-dimensionality and spatiality, can create a unique artistic atmosphere through the ingenious combination of form, line and light and shadow. At the same time, sculpture works are made of various materials, such as stone, wood, metal and ceramic, each of which gives the sculpture different texture and expressiveness. In addition, sculpture has strong durability and stability, and is not easy to be damaged, which can maintain its artistic value for a long time. However, traditional sculpture products are prone to cracking during the production process and after long-term storage, which affects their appearance and service life. SUMMARY

[0003] In view of the problem that existing sculpture works are prone to cracking, the present application provides a preparation method of anti-cracking sculpture products, the environment-friendly sculpture product comprises a body and a reinforcing body coated on the surface of the body; the body comprises the following substances by weight: cement powder 50-100 parts, oligomer 5-20 parts, fine denier matt short fiber 5-15 parts, adhesive 2-10 parts and retarder 0-0.05 parts; the reinforcing body is a polymer coating.

[0004] The preparation method comprises the following steps: 1) weigh each component of the body by weight, mix with an appropriate amount of water, pour into a mold, demold after shaping, and obtain a sculpture blank; 2) use a steel brush to make uniform holes on the surface of the sculpture blank obtained in step 1), and then use a steel brush to brush the surface of the sculpture blank to make it rough, so that the fine denier matt short fiber extends out of the body; 3) uniformly brush the reinforcing polymer coating on the surface of the sculpture blank treated in step 2), and after solidification, place it in a constant temperature oven for heating, and the anti-cracking sculpture product is obtained.

[0005] The oligomer and fine denier matt short fiber added in the body of the anti-cracking sculpture product will form a fiber composite material with the cement powder under the action of the adhesive, which can increase the anti-cracking ability of the body. The added oligomer can also make the mixture have a certain waxy nature, which is convenient for pouring, and the oligomer will reduce the crystallinity of the cement after isolation, and the overall integrity is higher after solidification under the action of the retarder, which reduces the possibility of cracking to a certain extent.

[0006] Further, the particle size of the cement powder is 20-200 μm; the oligomer is one of polyurethane oligomer, polyamide oligomer or epoxy resin oligomer; the fine denier dull short fiber has a fineness of 5-15D and a length of 1-10 mm and is made of one of PA, PE, PP or PET; the binder is water glass or silica sol; and the retarder is one or more of sodium gluconate, citric acid, ethylene glycol or sucrose.

[0007] Further, the reinforcing agent is one of polyurethane coating, epoxy resin coating or polyurea coating. In step 3) of the method, when the reinforcing agent is applied, the coating penetrates into the holes, and the short fibers protruding from the body after solidification are locked in the coating, so that the combination of the coating and the body is more firm, the anti-cracking ability of the sculpture product is further improved, and the sculpture product has a certain waterproof ability.

[0008] Further, pigments can be added to the reinforcing agent to improve the artistic value of the sculpture product. DETAILED DESCRIPTION
