Abstract
The present invention provides a kind of high-performance composite bentonite additive, including bentonite and additive, the mass ratio of bentonite and additive is 100:(15 ~ 50), described additive includes microcrystalline Cellulose, magnesium oxide or magnesium hydroxide, high-temperature explosion-proof agent, in described additive, the quality accounting of each material is: microcrystalline Cellulose 4% ~ 26%, magnesium oxide or magnesium hydroxide 12% ~ 80%, high-temperature explosion-proof agent 1% ~ 40%.Improve the thixotropy of product, viscosity and lubricity, thus improve the colloid index of product, and bentonitic swelling value and expansion capacity effectively improve, improve the expansion character of bentonitic entirety, thus reducing bentonitic raw material dosage, simultaneous oxidation magnesium and magnesium hydroxide can be effectively improved the value of bentonitic PH, and high-temperature explosion-proof agent makes bentonitic thermal stability good, there are higher plasticity and stronger caking property, hot green tensile strength and dry compression high.
Description
Technical field
The present invention relates to a kind of bentonite, be specifically related to a kind of composite bentonite containing additive.
Background technology
Bentonite is the nonmetallic minerals with montmorillonite as main mineral constituent, there is some cation in the layer structure formed due to montmorillonite structure cell, such as Cu, Mg, Na, K etc., and these cationes are the most insecure with the effect of montmorillonite structure cell, easily it is partially or completely exchanged by other cations, therefore there is preferable ion exchangeable.
Bentonite (montmorillonite) is owing to there being good physical and chemical performance, binding agent, suspending agent, thixotropic agent, stabilizer, purification and decoloration agent, casting resin, feedstuff, catalyst etc. can be done, it is widely used in agricultural, light industry and the field such as cosmetics, medicine, it is a kind of broad-spectrum natural minerals that people are referred to as " omnipotent soil " therefore bentonite, but how to improve the colloid index of product, improve bentonitic performance, reduce bentonitic raw material dosage and be particularly important.
Summary of the invention
For above-mentioned deficiency, the invention provides a kind of high-performance composite bentonite, by increasing the additive improving bentonite performance, improve bentonitic colloid index, reduce bentonitic raw material dosage so that bentonite has high-performance.
It is an object of the invention to provide a kind of high-performance composite bentonite, including bentonite and additive, the mass ratio of bentonite and additive is 100:(15 ~ 50), described additive includes microcrystalline Cellulose, magnesium oxide or magnesium hydroxide, high-temperature explosion-proof agent, in described additive, the quality accounting of each material is: microcrystalline Cellulose 4% ~ 26%, magnesium oxide or magnesium hydroxide 12% ~ 80%, high-temperature explosion-proof agent 1% ~ 40%.
Further improvement of the present invention is: described additive also includes attapulgite clay, and the quality accounting of described attapulgite clay is 4% ~ 20%.Can effectively strengthen bentonitic tackifying, suspension, thixotropy, thermal insulation, lubricity, and its chemical inertness is conducive to suppressing microorganism growth, has the feature of environmental protection.
Further improvement of the present invention is: described additive also includes the mixture of organic polymer, and the quality accounting of the mixture of described organic polymer is 0.05% ~ 5%.
Further improvement of the present invention is: the mixture of described organic polymer is the complex of sodium pyrophosphate or sodium polyacrylate or sodium pyrophosphate and sodium polyacrylate mixture with polyacrylamide, sodium pyrophosphate or sodium polyacrylate and the mass ratio of polyacrylamide is (0-2): 1.It is effectively improved bentonitic swelling value and expansion capacity, improves bentonitic expansion character, reduce bentonitic raw material dosage.
Further improvement of the present invention is: the mass ratio of described sodium pyrophosphate or sodium polyacrylate or sodium pyrophosphate and sodium polyacrylate mixture and polyacrylamide is 1:0.7.This ratio makes swelling value and expansion capacity obtain maximum enhancing, and reduces the cost of additive.
Further improvement of the present invention is: any mixing of described microcrystalline Cellulose one or both in carboxymethyl cellulose and hydroxymethyl cellulose.The characteristic of microcrystalline Cellulose can be effectively improved bentonitic viscosity, dilatancy, lubricity, suspension.
Further improvement of the present invention is: described high-temperature explosion-proof agent is explosion-proof fiber.Improve bentonitic stretch-proof, caking property and heat stability.
Beneficial effects of the present invention: by increasing microcrystalline Cellulose, improve the thixotropy of product, viscosity and lubricity, thus improve the colloid index of product, and bentonitic swelling value and expansion capacity effectively improve, improve the expansion character of bentonitic entirety, thus reduce bentonitic raw material dosage, simultaneous oxidation magnesium and magnesium hydroxide can be effectively improved the value of bentonitic PH, high-temperature explosion-proof agent makes bentonitic thermal stability good, there are higher plasticity and stronger caking property, hot green tensile strength and dry compression high.
The bentonite that the present invention provides has high-performance, especially has higher colloid index and expansion character, and can effectively reduce bentonitic raw material dosage.
