Abstract
The invention relates to a method for integrally molding foaming silicon rubber and a flexible material, which comprises the following steps of: prepressing the prepared foaming silicon rubber in a mold cavity; flatly placing the flexible material of which the surface is provided with grid-shaped micropores on the foaming silicon rubber; and closing a mold, and heating and pressurizing for certain time. By integrally molding the foaming silicon rubber and the flexible material, the field of application of the foaming silicon rubber is widened. The combination between the foaming silicon rubber and the flexible material is tighter through the grid-shaped micropores on the surface of the flexible material and the stripping is hard. The molded products have excellent decoration variable effects and unique texture, have the characteristics of water resistance, heat insulation, no toxin, and easy washing, and can be widely applied to the fields of industry, decoration, and the like.
Description
Technical field
The present invention relates to a kind of forming method of foamed silastic, the integral formation method of particularly a kind of foamed silastic and flexible material belongs to chemical technology field.
Background technology
Common foamed silastic moulding generally is to carry out moulding with 100% silicon rubber, develops into foamed silastic afterwards and other material carries out one-body molded such as metal, plastics, glass etc.The method of these moulding can change the intensity of foamed silastic and make its rigidity that become, but metal, plastics, glass all are hard materials, the parts that are made of one piece of they and foamed silastic are used to do some structural members or the stressed parts that are heated morely, and because its texture is harder, discomfort is fit to do decoration.
In addition, metal, plastics, glass are the bonding on surface with combining of foamed silastic, and it is stripped under the effect of external force easily.
Above deficiency has limited the expansion of foamed silastic application.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide a kind of foamed silastic and flexible material integrated method.
The object of the present invention is achieved like this:
A kind of foamed silastic forming method comprises: the foamed silastic for preparing is placed on precompressed in the die cavity, again the surface had the flexible material of latticed micropore to lie in above the foamed silastic, and closed die then, heating is forced into certain hour.Flexible material surface mesh trellis micropore evenly distributes, and pore area is less than or equal to 0.06 square millimeter.
Forming method of the present invention is reasonable, and it is one-body molded to select for use flexible material and foamed silastic to carry out, and has greatly widened the application of foamed silastic.And owing to have latticed micropore on the flexible material surface, make foamed silastic with it in conjunction with the time can see through latticed micropore hole be penetrated into the another side of flexible material, therefore, combining between foamed silastic and the flexible material is tightr, is difficult for peeling off.
The integrated goods of the present invention have excellent decoration variation effect and unique texture, and have waterproof, heat insulation, nontoxic, easy washing, the infinite characteristics of style style change, can be widely used in industry, decoration etc., broad market prospect.
The specific embodiment
Embodiment one: before the moulding, earlier mold temperature is adjusted to 180 ℃, 150kg/cm is transferred in mold pressing
2, the foamed silastic that will mix and have cuting slice is placed on the interior precompressed of die cavity for a moment then, makes foamed silastic evenly be full of die cavity; Again the surface there is latticed micropore flexible material to lie in above the foamed silastic, closed die, about about 5 minutes of the pressurization of heating can die sinking be taken out finished product.Flexible material surface mesh trellis micropore evenly distributes, and pore area is 0.05 square millimeter.
Embodiment two: before the moulding, earlier mold temperature is adjusted to 195 ℃, 230kg/cm is transferred in mold pressing
2, the foamed silastic that will mix and have cuting slice is placed on the interior precompressed of die cavity for a moment then, makes foamed silastic evenly be full of die cavity; Again the surface there is latticed micropore flexible material to lie in above the foamed silastic, closed die, about about 8 minutes of the pressurization of heating can die sinking be taken out finished product.Flexible material surface mesh trellis micropore evenly distributes, and pore area is 0.04 square millimeter.
Selection for flexible material, can use bafta (for example cotton) or science fabric, because common chemical ﹠ blended fabric is surpassing easy deformation under 150 ℃ the temperature, therefore the low shrink(LS) chemical fibre industry silk fabrics of general selection is such as geotextiles, cord fabric or lamp box advertisement cloth, and the heat-shrinkable of raw fibre is less than or equal to 5% for good under 190 ℃ of temperature.The effect of bafta moulding is relatively good, and cost is lower, belongs to preference.
Claims (6)
