Problems solved by technology

However, the production cost of calcium phosphate inorganic solid particles is relatively high. Usually, the solid particles directly prepared by precipitation method have a large particle size, which hinders the cleaning effect of calcium phosphate solid particles on the interdental spaces, and also hinders the use of calcium phosphate inorganic solid particles. Particles enter the dentinal tubules, reducing the anti-sensitivity properties of calcium phosphate abrasives
In addition, slightly soluble calcium phosphate inorganic substances will also cause eutrophication pollution to water bodies

Abstract

The embodiment of the invention discloses a bagasse/calcium phosphate composite material as well as a preparation method and application thereof. The preparation method comprises the following steps: soaking bagasse in an aqueous solution containing a calcium ion source until the bagasse is adsorbed to reach a saturated state, then adding a phosphate ion source until calcium ions in the solution are completely converted into phosphate calcium salt, and then carrying out centrifugal separation, drying and grinding to obtain the bagasse/calcium phosphate composite material. According to the bagasse/calcium phosphate core-shell composite material prepared by taking bagasse as a raw material, the cleaning performance, the elasticity and the sensitivity resistance of a calcium phosphate grinding material are improved, excellent biocompatibility is kept, in addition, the composite material is applied to an oral care product, the usage amount of the calcium phosphate grinding material can be reduced, and the service life of the oral care product is prolonged. Meanwhile, pollution caused by bagasse and calcium phosphate inorganic salt is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical fields of daily chemicals, oral medicine, nursing and cleaning products, and in particular to a bagasse / calcium phosphate composite material and a preparation method and application thereof. Background technique [0002] Calcium phosphate inorganic solid particles and their hydrates are toothpaste abrasives with the best taste and biocompatibility. Among them, the elemental composition of calcium hydrogen phosphate dihydrate, tricalcium phosphate and hydroxyapatite is similar to that of tooth enamel surface. The toothpaste prepared by using the above abrasive has a unique and delicate taste, and has outstanding performance in remineralization of enamel and anti-sensitivity of dentin. However, the production cost of calcium phosphate-based inorganic solid particles is relatively high, and the particle size of the solid particles directly prepared by the precipitation method is usually larg...
