Abstract

A process for preparing toothpaste or tooth powder from the rice husk ash as abrasive includes such steps as washing rice husk, drying burning, decarbonizing to obtain white rice husk ash, and proportionally mixing it with ordinary toothpaste or tooth powder. The product has high detergency.

Description

A kind of method and purposes of making toothpaste or dentifrice grinding agent of rice hull ash

Technical field

The present invention relates to a kind of manufacture method of article of everyday use batching, refer in particular to the manufacture method of grinding agent in a kind of daily toothpaste or the dentifrice; The invention still further relates to a kind of purposes of crops material handling, be meant a kind of purposes of rice husk especially.

Background technology

Toothpaste or dentifrice employed a kind of sanitary equipment articles for use when to be that people are daily be used for the cleaning oral cavity inner teeth gear.Raising along with people's living standard, people to the requirement of toothpaste or dentifrice more and more higher, various toothpaste or dentifrice are also more and more, fluorine-containing strong tooth is arranged, have and remove the tooth dirt, contain in addition that various Chinese herbal medicine are antibiotic cures the disease, but existing toothpaste or dentifrice is to consider to adjust prescription from taste, the mouthfeel of toothpaste or dentifrice and the angle of curing the disease mostly, therefore mainly is to realize by add some adjuvant on the basis of fundamental component.The grinding agent of toothpaste or dentifrice is the main fundamental component that toothpaste or dentifrice clean the teeth, and what is called is brushed teeth, and by the grinding agent that is bonded on the toothbrush friction of tooth is reached the purpose that cleans the teeth exactly.The grinding agent of existing toothpaste or dentifrice is many to be made of materials such as calcium carbonate or light aluminium oxidies, and improves seldom in this respect.Though these grinding agent price comparisons are cheap, the poor effect that cleans the teeth mostly particularly can not produce tangible effect to crock, tea stain and calculus.Recently in high-grade toothpaste or dentifrice also useful Margarita powder as grinding agent, though contain a lot of benefit materials in the Margarita powder, tooth protection is had certain effect, still be apparent not enough from the angle that cleans the teeth, and the Margarita powder price is higher, so only just use in high-grade toothpaste or dentifrice usually.Therefore, for how by selecting for use suitable grinding agent to reach the purpose that cleans the teeth, necessary really the analysis and research.

On the other hand, rice husk is one deck crust layer that is wrapped in the rice appearance, in the course of processing of rice, will get rid of the rice husk of rice appearance, and most applications is lost the extexine of the rice husk be up in the rice roughing as garbage, the internal layer that the rice husk that rice polish is laid contacts with rice is then made bran cake or bran powder as Testa oryzae, is used as feedstuff.China is a large agricultural country, and the output of annual Oryza glutinosa is at about about 200,000,000 tons, and the extexine of the rice husk of losing accounts for 20% of rice greatly, and promptly annual nearly 40,000,000 tons rice husk is lost.Also there is the people aspect the utilizing of rice husk, to move a large amount of brains, aspect the industrial utilization of rice husk except making fuel and fertilizer, current main application is to be used for extracting silicon dioxide or to make white carbon black, as Chinese patent notification number on July 30th, 2003 be CN1116128C disclosed " a kind of method of comprehensive utilization of rice husk " introduced a kind of will rice husk through being made into the method for silicon dioxide and activated carbon after burning, but only limit to industrial circles such as rubber, plastics, paint in application facet.Also useful rice husk is made reporting for work of construction material or degradable environment friendly material, but still finds no the report that rice husk is used for making toothpaste or dentifrice grinding agent by looking into new relevant patent documentation or other scientific and technical literature.

Summary of the invention

The objective of the invention is to propose a kind of better effects if that cleans the teeth at the clean the teeth deficiency of poor effect of existing toothpaste or dentifrice grinding agent, and with low cost, novel toothpaste simple for production or dentifrice grinding agent;

Another object of the present invention is to provide a kind of new purposes of rice husk.

The objective of the invention is to be achieved through the following technical solutions, rice husk is cleaned back airing or oven dry, place stove to carry out the albefaction burning again, decarburization is fired into white and has certain chemically active rice hull ash, again white rice hull ash is joined in toothpaste or the dentifrice as grinding agent by certain proportioning, promptly can be made into a kind of toothpaste or dentifrice abrasive that contains rice hull ash.

Rice husk burn the back prepared have in the chemically active white rice hull ash contain abundant silicon dioxide, sodium, composition such as potassium and calcium, wherein silicon dioxide has tangible corrasion to the tartar of tooth when making the grinding agent of toothpaste or dentifrice with it, and the sodium in the rice hull ash, potassium and calcium isoreactivity composition can play help to the tooth friction again, therefore to have the tartar of removing ability strong for the grinding agent of making toothpaste or dentifrice with rice hull ash, good effectiveness, and it is low to have price with the grinding agent that rice hull ash is made toothpaste or dentifrice, simple for production, play the effect of killing two birds with one stone that turns waste into wealth, be worthy of popularization.Rice hull ash also can be combined into the multiple grinding agent with other dental abrasive.

The specific embodiment

The present invention is described in further detail below in conjunction with specific embodiment.

Embodiment one

Rice husk is cleaned the back airing, directly place calcining furnace to carry out the high-temperature calcination of 800-1000 degree, rice husk albefaction in stove is burnt to white lime, stop burning again and leave standstill cooling 3-4 days, promptly become the grinding agent materials of available toothpaste or dentifrice.

With the rice hull ash that bakes be raw material and Oleum menthae, essence, saccharin sodium by weight ratio: 98: 1: 0.5: 0.1 allotment promptly can be made into available dentifrice.

Embodiment two

Rice husk is cleaned the back airing, directly place roasting furnace, carry out the low temperature roast with the mode that slowly heats up, make the Organic substance in the rice husk will fully decompose, gasify, rice husk albefaction in roasting furnace is burnt to white lime.Stop burning again and leave standstill cooling 3-4 days, promptly become the grinding agent materials of available toothpaste or dentifrice.

The rice hull ash that just bakes is raw material and glycerol, tetrasodium pyrophosphate, essence, three potassium sorbates, saccharin sodium and suitable quantity of water assembly, by weight: rice hull ash 25, glycerol 25, adhesive (CMC) 1, foaming agent (K ₁₃) 1, tetrasodium pyrophosphate 0.5, essence 0.1, three potassium sorbates 0.1, saccharin sodium 0.1, water 2 carry out proportioning, toothpaste production technology processing and can be made into the novel toothpaste that contains rice hull ash routinely again.
