Abstract
The invention discloses a formula and a process of a silicone rubber film-covered gasket. The silicone rubber film-covered gasket is prepared from the following components in parts by weight: 100 parts of silicone rubber, 40-50 parts of white carbon black, 1-3 parts of ferric oxide, 1 part of titanium dioxide, 1-3 parts of coupling agent and 0.5-0.8 part of vulcanizing agent. The process comprises the following production steps: step 1, dosing; step 2, rubber mixing; step 3, pre-molding; step 4, primary vulcanization; step 5, secondary vulcanization; step 6, edge removal; step 7, cleaning. On the basis of the traditional technique, the formula and the process of the silicone rubber gasket are improved, and a layer of fluorine film material is added on the basis of the original silicone rubber gasket so that the surface of the gasket can be covered with a layer of PTFE fluorine film material; the PTFE fluorine film material has relatively high chemical stability and biological sluggishness without affecting the quality of a packaged reagent.
Description
Technical field
The present invention relates to a kind of formula and technique of rubber sheet gasket, particularly relate to a kind of formula and technique of silicon rubber overlay film pad.
Background technology
Silicon rubber overlay film pad is mainly for detection of the encapsulation of examination use for laboratory standard test specimen, because inspection testing standard reagent has larger impact for detected result, therefore the fluctuation of quality can not appear in reagent in packing and storing process, therefore the stability of its seal gasket used is most important.Therefore, those skilled in the art needs a kind of new technical scheme badly and solves this problem.
Summary of the invention
Invent problem to be solved to be: the formula and the technique that provide a kind of silicon rubber overlay film pad, it effectively can ensure the quality of packaging reagent.
Technical solution problem of the present invention adopts following technical scheme:
A formula for silicon rubber overlay film pad, is made up of by weight following component: 100 parts, silicon rubber, white carbon black 40-50 part, ferric oxide 1-3 part, titanium dioxide 1 part, coupling agent 1-3 part, vulcanizing agent 0.5-0.8 part.
Preferably, described vulcanizing agent is vulcanizing agent two 25.
A technique for silicon rubber overlay film pad, comprises following production stage:
Step one, by formula various material formulation is good after put into the barrel of specifying, i.e. blending process;
Step 2, evenly mixing by material various in barrel, obtain sizing material, i.e. mixing process;
Step 3, as requested sizing material is made the film being convenient to sulfuration specified dimension weight, i.e. preform process;
Step 4, mould material to be attached on film, and to carry out a sulfuration, i.e. a sulfidation;
Step 5, the product that a sulfuration obtains is put into vacuum drying oven carry out post cure, the volatile component in removing product, i.e. secondary sulfurizing course;
Step 6, through die-cut formation finished product, namely except crack approach;
Step 7, cleaning rubber cushion, i.e. cleaning process;
Preferably, described mould material is PTFE fluorine mould material.
The invention has the beneficial effects as follows: the present invention is on the basis of conventional art, improve the composition and engineering of silicon rubber pad, the basis of original silicon rubber pad adds one deck fluorine mould material, gasket surface is covered one deck PTFE fluorine mould material, and PTFE fluorine mould material has higher chemical stability and biologically inert, the quality of packaging reagent can not be affected.
