example 1

[0024] Measure the sodium silicate solution with a mass fraction of 30%, adjust the pH to 5.0 with a hydrochloric acid solution with a concentration of 0.5mol / L, stir and react for 15 minutes, filter and separate to obtain a gel-like precipitate, and remove the gel-like precipitate according to a mass ratio of 2:1 Mix with 200-mesh calcium oxide powder for 10 minutes to obtain a paste mixture; weigh the flax straw and put it into a pulverizer to crush it and pass it through a 1.0cm aperture sieve to obtain flax straw fragments. Soak the flax straw fragments in water for 10 hours, take them out, and spread them in In the ceramic jar, when the thickness reaches 3cm, lay a layer of paste mixture with a thickness of 1cm on the top to completely cover the flax stalks, so that a layer of flax straw fragments and a layer of paste mixture are added until the flax straw layer and The paste mixture layer reaches 10 layers; after the laying is completed, pour clean water into the jar alon...

[0026]Measure the sodium silicate solution with a mass fraction of 30%, adjust the pH to 5.5 with a hydrochloric acid solution with a concentration of 0.5mol / L, stir and react for 18 minutes, filter and separate to obtain a gel-like precipitate, and remove the gel-like precipitate according to a mass ratio of 2:1 Mix with 200-mesh calcium oxide powder for 13 minutes to obtain a paste mixture; weigh the flax straw and put it into a pulverizer to crush it and pass it through a 1.3cm aperture sieve to obtain flax straw fragments. Soak the flax straw fragments in water for 11 hours, take them out, and spread them in In the ceramic jar, when the thickness reaches 4cm, lay a layer of paste mixture with a thickness of 1cm on the top to completely cover the flax stalks, so that a layer of flax straw fragments and a layer of paste mixture are added until the flax straw layer and The paste mixture layer reaches 10 layers; after the laying is completed, pour clean water into the jar along...

[0028] Measure the sodium silicate solution with a mass fraction of 30%, adjust the pH to 6.0 with a hydrochloric acid solution with a concentration of 0.5mol / L, stir and react for 20 minutes, filter and separate to obtain a gel-like precipitate, and remove the gel-like precipitate according to a mass ratio of 2:1 Mix with 200-mesh calcium oxide powder for 15 minutes to obtain a paste mixture; weigh the flax straw and put it into a pulverizer to crush it and pass it through a 1.5cm aperture sieve to obtain flax straw fragments. Soak the flax straw fragments in water for 12 hours, take them out, and spread them in In the ceramic jar, when the thickness is 5cm, a layer of paste mixture with a thickness of 2cm is laid on the top to completely cover the flax straw, so that a layer of flax straw fragments and a layer of paste mixture are added until the flax straw layer and The paste mixture layer reaches 10 layers; after the paving is completed, pour clean water into the jar along ...

Abstract

The invention relates to the technical field of sculpture material preparation and particularly relates to a preparation method of a high-strength water-proofing clay sculpture material. In the method, orthosilicic acid precipitate is mixed with quick lime to obtain a paste mixture, and flax straw and the paste mixture are soaked and fermented for a long time, so that the flax straw is mildewed, wherein grass tendon, which is high in toughness and strength, remain and is precipitated with the lime; the materials are heated and boiled so that the orthosilicic acid precipitate is heated and decomposed to generate nano SiO2 which is packed in the slurry, wherein the high-strength nano SiO2 can further increase the mechanical strength of cured and shaped slurry so as to finally obtain self-made tendon slurry which has very high viscosity and high strength; then clay mineral kaolin is blended with flour and castor oil to perform fermentation, so that castor oil is degraded to generate estergroups under effect of microorganisms, finally the ester groups are introduced to the surface of kaolin for improving the hydrophobicity and water resistance of clay to fially produce the high-strength water-proofing clay sculpture material, which has broad application prospect.

Description

technical field [0001] The invention relates to the technical field of sculpture material preparation, in particular to a preparation method of high-strength cement-proof plastic material. Background technique [0002] Existing sculpture materials mainly include clay sculpture, cement sculpture, stone sculpture, etc. Clay sculpture clay has strong plasticity, but poor strength and water resistance, so it cannot be used to make large-scale outdoor artworks. Cement sculpture must go through a series of operations such as molding and injection, which cannot perfectly and fully express the hand feeling of artists, but often cause the vivid sculpture shape and technique to be lost due to reproduction; pottery sculpture products must be processed through Roasting can obtain the petrification effect, but roasting limits large-scale production. Although the artificial marble and magnesite products widely used in the market have certain stone characteristics, they are not plastic an...
