Description
Technical field:
The present invention relates to LED bulb and manufacture technical field, be specifically related to a kind of production formula of LED bulb rubber gasket.
Background technology:
Under the background that Present Global energy starved worry raises once again, save energy is the important problem that we will face future, at lighting field, the application of LED luminous product is just attract the sight of common people, LED has the many merits such as light efficiency is high, long service life, energy-saving and environmental protection, is more and more widely used in various fields.It is the new type light source of 21 century, has the advantage that the conventional light source such as efficiency is high, life-span length, not cracky cannot compare with it.
But LED luminous product, especially LED lamp panel exist great heat dissipation problem, many times because the too high meeting of heat causes the problems such as circuit burn, serious impact will be caused on the use of LED product like this.Often some rubber sheet gasketings are installed on circuit boards additional in order to prevent the impact of some high temperature, these pads can reduce diffusion and the propagation of temperature to a great extent, prevent the mutual heat conduction of components connected, there is very strong effect of heat insulation, and this meeting of rubber sheet gasket with extremely strong abrasion resistant effect and extremely strong sealing effectiveness have revolutionary prolongation to the life-span of LED, and ensure that the safety performance of LED.
Summary of the invention:
Technical problem to be solved by this invention be to provide a kind of result of use good, there is effect of heat insulation and wear resistance, and there is the production formula of LED bulb rubber gasket of sealing effectiveness.
Technical problem to be solved by this invention adopts following technical scheme to realize:
The production formula of LED bulb rubber gasket, be made up of the raw material of following mass fraction:
Isoprene-isobutylene rubber 100-150 part, carbon nanotube 8-10 part, magnesiumcarbonate 3-8 part, calcium stearate 4-9 part, Diphenylsilanediol 3-5 part, coumarone indeneresin 2-4 part, rosin 1-2 part, trimellitic acid three monooctyl ester 1-3 part, kaolin 6-10 part, propolis 1 part, gas-produced black 2 parts, rapeseed oil 1-3 part, konilite 2-4 part, barium sulfate 1.5-2.5 part, resol 5-10 part, benzoyl peroxide 2-3 part, polyethylene 10-13 part, sodium lauryl sulphate 5-10 part, triethyl aluminum 5-8 part, magnesium hydroxide 3-5 part, white carbon black 8-12 part.
A production method for LED bulb rubber gasket, comprises the steps:
(1) be dissolved in by carbon nanotube in appropriate dimethylbenzene, ultrasonic 10-15min dissolves completely to make carbon nanotube, is dissolved in by isoprene-isobutylene rubber in appropriate ritalin completely simultaneously;
(2) carbon nano-tube solution of above-mentioned preparation and butyl rubber solution are mixed, join in twin-roll plastic mixing mill and plasticate after ultrasonic 5-10min, roller temperature control is at 45-55 DEG C, and plasticate time 10-15min;
(3) add the mixing 20-30min of all the other raw materials more successively, thin-pass 3-5 time, filter glue in rubber strainer after, be cooled to room temperature;
(4) rubber unvulcanizate is added die cavity, utilize compression molding agent sulfidization molding, curing temperature is 150-160 DEG C, curing time 30-35min.
The invention has the beneficial effects as follows: composition of raw materials of the present invention is novel, production technique is simple, and the rubber gasket of preparation has good result of use, has stronger effect of heat insulation and wear resistance, and has sealing effectiveness long service life.
