Description
Technical field
The present invention relates to a kind of mould making method, specifically, relate to a kind of silica gel mould preparation method.
Background technology
Silica gel mould is the particular manufacturing craft glue of craft articles, and the feature of silica gel is high temperature resistant, corrosion-resistant, and anti-tear drawing property is strong, and emulating meticulous height, is the particular manufacturing craft making various handicraft.Silica gel kitchen utensils material point can be divided into by performance that common silica gel is gentle resembles silica gel.But, existing silica gel mould production technology is perfect not enough, in the production process of reality, reaction time is difficult to control, and the silica gel mould defect produced is many, in addition, in the production of silica gel mould, harden phenomenon in easy generation local, causes the surface smoothness of silica gel mould poor, finally affect silica gel mould product quality and production efficiency.
Summary of the invention
The object of the invention is to overcome above-mentioned defect, provide a kind of and realize conveniently, production cost is low, the preparation method of the silica gel mould of environmental protection.
To achieve these goals, the technical solution used in the present invention is as follows:
A preparation method for silica gel mould, comprises the following steps:
(1) by silica gel: curing agent: silicone oil: mill base: the raw material of the weight ratio configuration production mould of granular polystyrene=100:3-3.5:2-5:0.2-0.4:0.5-2.5;
(2) silica gel is contained into plastic cement basin;
(3) silicone oil, mill base, granular polystyrene to be added in plastic cement basin and to stir with silica gel, static 2-5 minute;
(3) curing agent is added in plastic cement basin and carry out mixing and stirring;
(4) silica gel diluent is added, till mixing;
(5) row steeps 1-3 minute under negative pressure;
(6) before mould is uncured, be pressed on mould after employing is air-dry with mold plane flexible sheet material external coating releasing agent of the same size, meanwhile, with cylinder roll extrusion sheet material, directly only flatten silica gel mould;
(7) sheet material is adopted to push down silica gel mould, straight anti-avulsion mould.
Further, described silicone oil is methyl-silicone oil.
Further, described curing agent is ethyl orthosilicate or organotin.
Further, in described step (4), incorporation time is 4 minutes.
Further, described flexible sheet material is lucite, PVC board or thick template, and the bending number of degrees are 15-30 °.
Further, the panel weight adopted in described step (7) is greater than the flexible sheet material in described step (6).
Further, calculate with weight ratio, the raw material of described silica gel mould is as follows: silica gel: curing agent: silicone oil: mill base: granular polystyrene=100:3:4:0.5:1.5.
Compared with prior art, the present invention has following beneficial effect:
(1) the present invention is simple to operate, perfect, various curing agent is added in the process made, fully control the various reaction time well, the silica gel mould produced have high temperature resistant, corrosion-resistant, anti-tear drawing property strong, emulate meticulous high various advantage, for it is applied on a large scale, establish solid foundation.
(2) the present invention is before silica gel mould is uncured, carry out pressing process, the silica gel mould surfacing be made thus, effectively overcomes in the production of existing silica gel mould, harden phenomenon in easy generation local, causes the problem of the surface smoothness difference of silica gel mould.
(3) the present invention adds benzene particle and silicone oil, and because the large density of granular polystyrene volume is little, quality is light, and the mould made not only reduces price, and light weight; And silicone oil can reduce the contraction of silica gel, therefore make the silica gel mould made not yielding, overcome the defect that existing silica gel mould cost is high, quality is large.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
