Abstract

The invention discloses a kind of preparation methods making diatomite high temperature sintering, include the following steps:1) proportioning based on following weight percent weighs each raw material:Diatomite:60-65%;Kaolin:8-13%;Pyrophyllite:6-12%;Bentonite:5-10%;Calcium carbonate:7-12%;pva:0.8-1.2%;Aluminium oxide:3-8%;2) diatomite is mixed with kaolin, and 20-30min is heated at a temperature of 1000-1150 DEG C will be passed through in the stove mixed;3) pyrophyllite, bentonite, calcium carbonate, pva and aluminium oxide are mixed, and mixture and diatomite before and kaolinic mixture is mixed.A kind of preparation method making diatomite high temperature sintering disclosed by the invention, water absorbing capacity is strong, and environmental protection does not waste, not easily to fall off.

Description

A kind of preparation method making diatomite high temperature sintering
Technical field
The present invention relates to craftwork production material field, in particular to a kind of preparation methods making diatomite high temperature sintering.
Background technology
Currently, China prepare diatomaceous craftwork be all with chemical coagulation it is molding, can not use high temperature sintering, normally Just become powder under 150 degree.Commonly with diatomite technique product made of chemical coagulation, diatomite content is not high normally to be only had 20-30% or so is silicate using craftwork main component made of this material, and surface leads to its appearance without coagulated substance Easily picking, water absorbing force reduce in use for some time, until not absorbing water.It is easy to fall off under the environment of cleaning or humidity.
Invention content
To solve the problems mentioned in the above background technology, the purpose of the present invention is to provide one kind, and diatomite high temperature to be made to burn The preparation method of knot, good heat-insulation effect, water absorbing capacity is strong, and environmental protection does not waste.
In order to solve the above technical problems, technical solution provided by the invention is:
A kind of preparation method making diatomite high temperature sintering, includes the following steps:
1) proportioning based on following weight percent weighs each raw material:Diatomite:60-65%;Kaolin:8-13%;Leaf Alabaster:6-12%;Bentonite:5-10%;Calcium carbonate:7-12%;pva:0.8-1.2%;Aluminium oxide:3-8%;
2) diatomite is mixed with kaolin, and is heated at a temperature of 1000-1150 DEG C will be passed through in the stove mixed 20—30min;
3) pyrophyllite, bentonite, calcium carbonate, pva and aluminium oxide are mixed, and by mixture and diatomite before It is mixed with kaolinic mixture.
Preferably, the diatomite and kaolin mixture after the heating, are cooled to room temperature, and it is broken to carry out regrinding The mixture mixed again with pyrophyllite, bentonite, calcium carbonate, pva and aluminium oxide after broken mixes.
The beneficial effects of the invention are as follows:
Using the method (1000 degree of temperature or more) of physics high temperature sintering, diatomite content is up to 60% or more, really with silicon Diatomaceous earth is primary raw material, the diatomite of high-content, and distinctive molecular sieve structure is reachable using the craftwork water absorbing force of this formula It is inhaled to the second, water absorption also greatly increases, and diatomite picking not easily to fall off, water suction a period of time are made by the way of high temperature sintering Afterwards, it can be made to restore water absorbing force with the mode that the sun shines, achievees the purpose that reuse, it is more environmentally-friendly, it does not waste.It is high simultaneously The diatomite of content, using the superpower insulative properties of diatomite, the craftwork prepared using this mode be really achieved it is good every Thermal effect.
Specific implementation mode
Illustrate the present invention with specific embodiment below, is not limitation of the present invention.
