Below provide the instantiation of the preparation method of three looks solid-state silica gel product.
Example 1
1, spray a kind of special releasing agent in the product cavity surface of the first patrix 1, second patrix 2, make product cavity surface glue silica gel materials.
2, whole mould is placed on ordinary hot pressing machine, mould and die preheating is heated up.
3, mould die sinking, counterdie 4 and the first patrix 1 are opened, and the first look silica gel materials of the first product of the same colour is put into counterdie 4 die cavity, mould matched moulds hot pressing product.The cure time of the first product of the same colour is 30s ~ 400s, and forming temperature is 60 ~ 180 °, briquetting pressure 50 ~ 200Ton.The silica gel materials of the first product of the same colour is when sulfuration of the same colour, and the non-full maturity of raw material, sulphidity accounts for 20% ~ 40% of complete cure degree.
4, after hot-forming, the first product of the same colour does not need to take out in counterdie 4, stays in counterdie 4 die cavity.
5, mould die sinking, utilizes board to be slipped by the first patrix 1, adds the second look silica gel materials (or second product of the same colour) on the product of the same colour of first in counterdie 4, mould matched moulds, hot-forming two look products; The condition of molding of hot pressing two look product is: cure time is 30s ~ 400s, and forming temperature is 60 ~ 180 °, briquetting pressure 50 ~ 200Ton.After secondary hot pressing is shaping, the first product of the same colour bonds with the second look silica gel materials (or second product of the same colour) completely, forms two look products 12.Two look product silica gel materials are when post-cure, and the non-full maturity of raw material, sulphidity accounts for 20% ~ 40% of complete cure degree.Product of the same colour now has accounted for 40% ~ 80% of complete cure.
6, mould die sinking, utilizes board to be slipped by the second patrix 2, adds the 3rd look silica gel materials on two look products 12 in counterdie 4, mould matched moulds, hot-forming three look products.The condition of molding of hot pressing three look product is: cure time is 30s ~ 400s, and forming temperature is 60 ~ 180 °, briquetting pressure 50 ~ 200Ton.Three times hot-forming after, two look products 12 bond with the 3rd look silica gel materials completely, and the product of three kinds of colors glues layer by layer mutually.Now complete cure is ripe for the product of three kinds of colors.
7, final three look products take out by mould die sinking.
Step 3 ~ 7 can be repeated and carry out hot pressing three look product.
Example 2
As shown in Figure 4 and Figure 5, be with example 1 difference, while the hot-forming two look products 12 of step 6, the 3rd look silica gel materials can be put into the 3rd product die cavity 7 of the same colour between the 3rd patrix 3 and the second patrix, the product 10 of the same colour of hot pressing the 3rd simultaneously;
During mould die sinking, two look products 12 are stayed in the die cavity of counterdie 4, and the 3rd product of the same colour 10 is stayed in the die cavity of the 3rd patrix 3;
After die sinking, board is utilized to be slipped by the second patrix 2, by the 3rd patrix 3 and counterdie 4 matched moulds, by the 3rd product 10 of the same colour and the hot-forming three look products of two look products 12.
Above content combines concrete/preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its embodiment that can also describe these makes some substituting or modification, and these substitute or variant all should be considered as belonging to protection domain of the present utility model.
