Description
Affiliated technical field: the invention belongs to the preparation technology field of garment machinery with fitment material, specifically is a kind of preparation method of silicone rubber sponge backing board.
Background technology: in the prior art, be used for the ironing equipment of smooth clothes in the Clothing industry, between surface layer that contacts with cloth and equipment flat layer, generally will fill up the last layer spongy layer or claim foamed material layer.And spongy layer commonly used at present is common foam material, and is shaped as tabular, middle no hole, and its heat resistance is low, work-ing life short, and hardness can not meet high-quality requirement, and permeability is bad, influences quality product.
The objective of the invention is in order to remedy the deficiencies in the prior art, for people provide a kind of can be high temperature resistant, can use repeatedly, hardness can regulate the preparation method of the silicone rubber sponge backing board of using in the ironing equipment of the smooth clothes that permeability is good.
The objective of the invention is to realize by following technical proposals.
Summary of the invention: the preparation method of silicone rubber sponge backing board of the present invention is divided into the preparation of basic glue, mixing, moulding, one step cure, five steps of post vulcanization:
Basis glue preparation: basic glue is the methyl vinyl silicone rubber rubber unvulcanizate, directly buy from manufacturer, or be 100% in basic glue, press 110-2 type methyl vinyl silicone rubber 54～75%, the white carbon black 20～45% of the precipitator method, viscosity are the ratio batching of the hydroxy silicon oil (as constitution controller) 1～10% of 20～25PAS, in kneader under 170～190 ℃, the vacuum of 0.09MPa, mediated 1～2 hour, getting hardness is the basic glue of 30～45SHA;
Mixing: in the product gross weight is 100%, by basic glue 80～95%, vulcanizing agent 0.5～1%, and whipping agent 3～10%, the ratio batching of pigment 0～10% is carried out mixing in mixing machine under the normal temperature; Described vulcanizing agent is the two 25[2 of DCP (dicumyl peroxide), vulcanizing agent, 5-dimethyl-2, two (tert-butyl peroxy base) hexanes of 5-], BPO (benzoyl peroxide); Described whipping agent is blowing agent AC (Cellmic C 121), blowing agent H (N, N-dinitroso five methyne tetramines) or sodium bicarbonate (sodium bicarbonate);
Moulding: after the glue after mixing leaves standstill 24 hours～7 days, at the sheet material that on two roll calender or the tri-roll press machine above-mentioned glue laminated after mixing is prolonged into desired thickness;
One step cure: the sheet material after the moulding is put into mould, under the pressure of 170～200 ℃ of temperature, 20Mpa, (acts on the pressure of mould), carry out high temperature vulcanized and the foaming 10～15 minutes; Described lower mould is plate, and patrix is the cover plate of indent, and cover plate is provided with cylindricality nail and netted tongue or meshed grooves; The height of patrix is more than or equal to the required thickness of the finished product;
Post vulcanization: the sheet material with holes behind the one step cure is inserted in the baking oven, vulcanized 2 hours down, get the silicone rubber sponge backing board that the finished product have through hole and groove in 180 ℃.
In the such scheme, be added with 0～5% methyl-silicone oil (is 100% in basic glue) in the basic glue preparation process.
Glue time of repose after mixing in the forming step is preferably 3 days.
Among the preparation method of silicone rubber sponge backing board of the present invention, in the basic glue preparation process, the intensity and the elongation of the adjustable basic glue of adding of white carbon black.Sheet metal thickness during moulding is adjustable.During one step cure, the height of patrix promptly can free foaming greater than the height of required the finished product.
Under the identical situation of sizing amount, the foaming dosage what can determine volume density; Under the identical situation of mould size, what of feeding quantity can determine volume density.
Inventor of the present invention adopts whipping agent to foam to prepare silicone rubber sponge backing board, has studied the kind of the kind of whipping agent and consumption, basic glue and consumption and foaming process conditions to the finished product Effect on Performance; And well-designed unique mould, the silicone rubber sponge backing board of using in the ironing equipment of the smooth clothes that having prepared can be high temperature resistant, can use repeatedly, hardness can be regulated, have through hole and groove, permeability is good has remedied the deficiencies in the prior art.
