Embodiment 1

[0024] In this embodiment, a binder for the production of fluorite balls includes 15 parts of caustic soda and 30 parts of cornstarch in parts by weight.

[0025] The cornstarch is obtained through the following steps: adding raw cornstarch into a reaction kettle, adding water, raising the temperature to 45°C, mixing into a slurry, adding acetic acid to adjust the pH of the slurry to 6-7, adding а-starch Enzyme, enzymatic hydrolysis reaction at 45°C for 50 minutes, after the enzymolysis is complete, add acrylic acid, hydrogen peroxide and epoxy resin, keep the temperature at 45°C, ultrasonically react for 15 minutes, and obtain corn starch after the final slurry is dried.

[0026] Wherein, based on 100 parts of raw corn starch, 300 parts of water, 0.1 part of а-amylase, 13 parts of acrylic acid, 3 parts of hydrogen peroxide and 15 parts of epoxy resin are added.

Embodiment 2

[0028] In this implementation, a binder for the production of fluorite balls comprises 10 parts of caustic soda, 20 parts of cornstarch and 4 parts of water glass in parts by weight.

[0029] The cornstarch is obtained through the following steps: adding raw cornstarch into a reaction kettle, adding water, raising the temperature to 40°C, mixing into a slurry, adding acetic acid to adjust the pH of the slurry to 6-7, adding а-starch Enzyme, enzymatic hydrolysis reaction at 40°C for 70 minutes, after the enzymolysis is completed, add acrylic acid, hydrogen peroxide and epoxy resin, keep the temperature at 40°C, ultrasonically react for 20 minutes, and obtain corn starch after the final slurry is dried.

[0030] Wherein, based on 100 parts of raw corn starch, 200 parts of water, 0.3 parts of а-amylase, 10 parts of acrylic acid, 6 parts of hydrogen peroxide and 10 parts of epoxy resin are added.

[0031] The Baume degree of described water glass is 40.

Embodiment 3

[0033] In this embodiment, a binder for the production of fluorite balls includes, in parts by weight, 12 parts of caustic soda, 24 parts of cornstarch and 9 parts of water glass.

[0034] The above-mentioned adhesive for the production of fluorite balls, the cornstarch is obtained through the following steps: adding raw cornstarch into the reaction kettle, adding water, raising the temperature to 45°C, mixing to form a slurry, adding After adjusting the pH of the slurry to 6-7 with acetic acid, add а-amylase, and perform an enzymatic hydrolysis reaction at 45°C for 60 minutes. After the enzymolysis is complete, add acrylic acid, hydrogen peroxide and epoxy resin, keep the temperature at 45°C, and After reacting for 20 minutes, cornstarch can be obtained after the final slurry is dried.

[0035] The adhesive used for the production of fluorite balls is based on 100 parts of raw corn starch, 260 parts of water, 0.2 parts of α-amylase, 11 parts of acrylic acid, and 5 parts of hy...

Abstract

The invention discloses an adhesion agent for fluorite ball production. The adhesion agent comprises the following components in parts by weight: 10-15 parts of caustic soda and 20-30 parts of corn starch. The adhesion agent has the beneficial effects that formula is simple and cost is low due to extensive raw material source; forming effect is good due to low C and S content of the adhesion agent; the requirement for fluorite ball production is met due to good adhesive effect and good high-temperature resistant property; a prepared fluorite ball has good strength and can achieve the compressive strength by 6-9N / mm<2>; and the produced fluorite ball does not generate the phenomenon of pulverization by being thrown in the air at 5 meters and falling on a concrete floor.

Description

[0001] Technical field: [0002] The invention relates to an adhesive, in particular to an adhesive used in the production of fluorite balls. [0003] Background technique: [0004] Fluorite is widely used in the metallurgical industry. It can lower the melting point of refractory substances, promote the flow of slag, separate the slag and metal well, improve the desulfurization and dephosphorization process in the smelting process, and enhance the malleability and properties such as tensile strength. Therefore, it is widely used as a flux in iron and steel smelting and ferroalloy production, ferrochemical process and non-ferrous metal smelting. In recent years, high-grade fluorite raw ore has been mined in large quantities, and the reserves have been continuously reduced. The price of high-grade fluorite lump ore in the market has been rising and it is difficult to buy. Glass, ceramics, and chemical industries have switched to high-purity flotation fluorite powder, but the me...
