Abstract
The invention provides a fossil pottery and a preparation method thereof. The fossil pottery is prepared by mixing 35-45 percent of fossil by mass and 55-65 percent of clay by mass, wherein the fossil consists of 70-75 percent of ferroferric oxide by mass, 10-15 percent of silicon dioxide by mass, 5-10 percent of calcium carbonate by mass, 1-3 percent of manganese dioxide by mass, 1-3 percent of potassium oxide by mass and 0.01-0.03 percent of strontium carbonate by mass. According to the fossil pottery and the preparation method thereof, the problems of large pottery porosity and low compressive strength of an existing pottery can be solved, the production cost can be reduced, and the product quality can be ensured.
Description
Technical field
The present invention relates to pottery preparation field, be specifically related to a kind of fossil pottery and preparation method thereof.
Background technology
Pottery by clay or based on the mixture of clay, feldspar, quartz etc., through the general name of goods that are shaping, dry, that fire.Existing pottery is due to the difference of production technique and formula, and performance has larger difference, not of uniform size as porosity, and the height of ultimate compression strength differs.Through researching and analysing, the size of porosity directly affects the work-ing life of pottery, and porosity is larger, and the water in pottery more easily permeates, and then causes reduce the work-ing life of pottery; Ultimate compression strength is also the important factor being directly connected to pottery work-ing life, and the size of porosity also directly can have influence on the ultimate compression strength of pottery, and porosity is larger, and ultimate compression strength will corresponding step-down; In order to reduce porosity, the way that manufacturer is general clay is crushed to 100 object particles, the diameter of particle is less, porosity is naturally less, but cause the viscosity ratio of entirety when making moulded pottery not yet put in a kiln to bake poor like this, need strictly to control well water content, not easy-formation, improve production cost; In order to increase the ultimate compression strength of pottery, some manufacturer adds fiber inside compound, but in the process of sintering, fiber from the surperficial emersion of pottery, can cause the surperficial uneven of pottery, the extreme influence quality of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fossil to make pottery and preparation method thereof, can solve current pottery porosity large, the problem that ultimate compression strength is low, and can reduce production cost, ensures quality product.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of fossil pottery, and be that the fossil of 35-45% and the clay of 55-65% are mixed by mass percent, described fossil consists of the following composition and the massfraction of each component is:
Described clay consists of the following composition and the massfraction of each component is:
As preferably, the fineness of described fossil is 150-200 order.
As preferably, the fineness of described clay is 150-200 order.
A preparation method for fossil pottery, comprises the following steps:
Step one: adopt pulverizer to pulverize block fossil, then the fossil after pulverizing is crossed 200 mesh sieves, select the fossil particle of below 200 orders; Then the fossil particle below 200 orders is crossed 150 mesh sieves, select 150-200 object fossil particle;
Step 2: fossil particle and clay are put into batch mixing in stirrer according to said ratio, and the mixing that adds water, then dewatered by pressure filter, make the mud cake that water ratio is 15-20%, and carry out old;
Step 3: mud cake is made moulded pottery not yet put in a kiln to bake, puts into after naturally drying in electrical kiln and sinters with 700-800 DEG C, make crude pottery, be cooled to room temperature;
Step 4: be immersed in by crude pottery in muddy liming, ceaselessly passes into carbon dioxide in muddy liming simultaneously, and take out after soaking 2-5 hour, utilize clear water to wash away inside and outside crude pottery, then dry, bake out temperature is 200-250 DEG C;
Step 5: the crude pottery after drying is put in electrical kiln, carries out double sintering with 1000-1300 DEG C, make finished product.
As preferably, take out after crude pottery being soaked 2 hours in described step 4, wash away with clear water; Again soak after 2 hours and take out, then wash away with clear water.
Beneficial effect:
The present invention adopts technique scheme to provide a kind of fossil to make pottery and preparation method thereof, can solve current pottery porosity large, the problem that ultimate compression strength is low, and can reduce production cost, ensures quality product.
