Abstract
A disclosed rubber sealing strip is characterized by being composed of the following compositions in percent by mass: 30% of ethylene-propylene-diene rubber, 1-1.5% of polyethylene glycol, 15-30% of aluminium hydroxide, 5-15% of a phosphate, 10-15% of carbon black, 10-20% of paraffin oil, 3% of calcium oxide, and 1% of sulfur. The invention also discloses a processing method of the rubber sealing strip. The processing method is characterized by comprising the following steps: weighing, mixing, standing for cooling, extrusion of a product, heat vulcanization and water-cooling shaping. According to the rubber sealing strip and the production method thereof, the rubber sealing strip is good in flame retardation effect, green and environment-friendly.
Description
Technical field
The present invention relates to a kind of rubber item, particularly relate to a kind of rubber weather strip and production method thereof.
Background technology
The matrix of existing vehicle, equipment, sealed strip for building generally has terpolymer EP rubber, terpolymer EP rubber is a kind of saturated rubber, there is excellent heat-resisting, resistance to weather and electrical property, and it is moderate, technical maturity, being the preferred material of automobile, boats and ships, railway, electric installation, is current the most widely used sealed strip matrix.
But the using function of terpolymer EP rubber rubber weather strip domestic is at present only limitted to sealing, also do not consider other factors such as fire-retardant, environmental protection.In European Union, all rubber items have required not containing nitrosamine, halogen, heavy metal etc., but are not also specified this factor fire-retardant.But then require fire-retardant in the U.S., European Union by force to door and window sealing strip for building, the matrix of these sealed strips is mostly polyvinyl chloride, chloroprene rubber and other thermoplastic elastomers and makes, and does not meet existing environmental requirement.Current sealed strip industry also exists industry-by-industry and requires skimble-scamble phenomenon, not environmentally fire-retardant, and environmental protection is not fire-retardant.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of good flame retardation effect, the rubber weather strip of environmental protection and production method thereof.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of rubber weather strip, is made up of the component calculated by mass percentage as follows:
Terpolymer EP rubber 30%
Polyoxyethylene glycol 1-1.5%
Aluminium hydroxide 15-30%
Phosphoric acid ester 5-15%
Carbon black 10-15%
Paraffin oil 10-20%
Calcium oxide 3%
Sulphur 1%
A production method for rubber weather strip, comprises the following steps:
The first step, weighs according to respective mass percent respectively to the constitutive material of India-rubber strip;
The various raw materials of having weighed are put in Banbury mixer mixing by second step, and by air pressure adjustment to 0.5Mpa, temperature remains on 120 DEG C, 400 seconds mixing time length;
3rd step, is undertaken parking cooling by mixing gained sizing material, and parking the time length is 36 hours;
4th step, arranging extruder temperature is screw rod 75 DEG C, head 95 DEG C, adjustment of rotational speed to 60 revs/min, extruded product;
5th step, carries out baking by extruded product, makes heating container temperature remain on 260 DEG C, and the time length is 100 seconds;
6th step, by the product that vulcanizates through water-cooled shaping.
Compared with prior art, the beneficial effect that the present invention has is:
With the addition of aluminium hydroxide, carbon black, paraffin oil in the component of 1, product rubber weather strip of the present invention, flame retardant properties and the extrusion performance of sizing material can be improved.
2, the aluminium hydroxide in product rubber weather strip component of the present invention, can absorb the heat of surrounding, reducing temperature when burning.Simultaneously at the Surface Creation mass crystallization water of combustionmaterial, isolation combustionmaterial contacts with oxygen, thus plays good flame retardant effect, aluminium hydroxide is again very good smoke suppressant simultaneously, the gas that combustionmaterial produces can be suppressed, thus do not produce smog, can accomplish that environmental protection is produced.
