Description

The crystallite bamboo charcoal pelelith pottery product of high absorption property and preparation method

Technical field

The present invention relates to pottery product, specifically the crystallite bamboo charcoal pelelith pottery product of a kind of high absorption property and preparation method.

Background technology

At home and abroad have many patented technologies about the bamboo charcoal ceramic ceramic material utilizing bamboo charcoal and other combinations of materials to make and goods at present. Through retrieval, with " bamboo charcoal " and " pottery " for the domestic invention disclosed patent of keyword search, only the performance of bamboo charcoal material is proposed concrete technological requirement by only a few patent in patent claim, all the other most of patents do not illustrate the technical specification of bamboo charcoal raw material, therefore can not give full play to the superior function of bamboo charcoal and have impact on the result of use of bamboo charcoal pottery material.

About in the patent of invention of bamboo charcoal ceramic, the patent that bamboo charcoal material proposes concrete technology requirement has:

Patent of invention " manufacture method of a kind of bamboo charcoal zisha ware beads " (publication number CN101311137A) claim 2 is: described bamboo charcoal powder is fired at 1000-1180 DEG C by bamboo charcoal.

Patent of invention " carried magnetic metallic surface ceramic stephanoporate bamboo charcoal wave-suction material and preparation method thereof " (publication number CN101269992) claim 3 is to be soaked in expanding agent at least 10 hours after drying by the bamboo chip being processed into required form and size, then by the bamboo chip after immersion 120 DEG C of drying; Again the temperature of 800-1000 DEG C, carbonization 1-3 hour under inert gas shielding atmosphere, prepare bamboo charcoal piece.

The firing temperature being only required to raw material bamboo charcoal in claims of above-mentioned two patents of invention is " 1000 DEG C ~ 1180 DEG C " and " 800 ~ 1000 DEG C " respectively. The bamboo charcoal burnt out at these temperatures can not change the arrangement of microcrystal, it is impossible to forms crystallization bamboo charcoal. With the pottery product that this bamboo charcoal material and other raw material are made, the function of bamboo charcoal can not give full play to, and rupture strength is low, and the adsorption rate of the harmful substances such as PARA FORMALDEHYDE PRILLS(91,95), phenol, sulfur dioxide is low.

Summary of the invention

It is an object of the invention to as overcoming the deficiencies in the prior art, and crystallite bamboo charcoal pelelith pottery product that a kind of high absorption property is provided and preparation method thereof.

The technical scheme realizing the object of the invention is:

The crystallite bamboo charcoal pelelith pottery product of a kind of high absorption property is, mud refining, molding blended with following raw material and materials weight part ratio, fire and form:

Clay 10-40.

Described crystallite bamboo charcoal powder is through 400-450 DEG C of carbonization with bamboo wood, then through 850 DEG C of activation, finally fires by three steps of 1200-1300 DEG C of crystallization and forms, and the size-reduced crystallite bamboo charcoal powder made, mean diameter is 30-100 ��m.

The mean diameter of described volcano stone powder is 10-50 ��m, and its performance characteristic is: unit weight��780Kg/m3; Specific surface area >=10m2/g, porosity of=70%.

The mean diameter of described purple pottery mud powder is 10-50 ��m.

Described clay be in Kaolin, bentonite, attapulgite, unselected clay any one or two or more mixed.

The preparation method of the crystallite bamboo charcoal pelelith pottery product of above-mentioned high absorption property, comprises the steps:

(1) crystallite bamboo charcoal powder, volcano stone powder, purple pottery mud powder and clay are weighed by materials weight;

(2) above-mentioned each raw material is stirred mixing in proportion, grind to form pug;

(3) mixture of step (2) is put into granulator granulation, or is placed in vacuum pugmill mud refining, place 24 hours naturally old after moulding on demand, obtain shaping blank;

(4) by shaping blank natural air drying, or it is placed in 80 ~ 100 DEG C of temperature drying of baking oven setting;

(5) dry blank is placed in kiln, is to slowly warm up to 800 ~ 1000 DEG C of calcinings at reducing atmosphere, be incubated 30 ~ 50 minutes.

(6) above-mentioned calcined material is naturally cooled to room temperature, prepare crystallite bamboo charcoal pelelith pottery product.

The invention have the advantage that owing to bamboo charcoal and pelelith have absorption property and the environmental purification function of uniqueness, bamboo charcoal and pelelith are combined and makes composite ceramic material, its existing certain mechanical strength is made to have again good absorption property and environmental purification function, there is percent of firing shrinkage low, rupture strength is big, the adsorption rate of PARA FORMALDEHYDE PRILLS(91,95), phenol, sulfur dioxide, TVOC and other harmful substances is strong, can be widely used in building and ornament materials, art and etc. field, drastically increase scientific and technological content and the economic worth of ceramic industry product.
