Abstract

The invention discloses one kind without asbestos seal gasket and preparation method thereof, this includes following raw material components without asbestos seal gasket, percentage：NBR 10 26%, aramid fiber 5 20%, white carbon 5 15%, molding powder 5 15%, fine particle calcium carbonate 10 20%, mica powder 12 20%, barium sulfate 10 20%, age resistor 1 5%, vulcanizing agent 1 5%.The present invention has good sealing property, high temperature resistant, tensile strength without asbestos seal gasket and crushing resistance is strong, resilience is high.

Description

Without asbestos seal gasket and preparation method thereof
Technical field
The invention belongs to chemical material technical field, more particularly, to one kind without asbestos seal gasket and its preparation side Method.
Background technology
Encapsulant is plant equipment, device and the indispensable part of pipeline junction.Tradition without asbestos board pad, because including fiber with There is micro space between rubber, tissue is loose, and density is not high, and compression strength is relatively low.In use due to have micropore and Resilience is not enough, easily causes leakage, and on the other hand tradition often uses benzene as molten without asbestos board pad during manufacturing Agent, the problems such as certain harm being caused to producers and environment.
The content of the invention
For problems of the prior art, it is an object of the invention to provide one kind without asbestos seal gasket and its system Preparation Method, this has good sealing property, high temperature resistant, tensile strength without asbestos seal gasket and crushing resistance is strong, resilience is high.
To achieve the above object, one kind of the invention is without asbestos seal gasket, and percentage includes following raw material Component：
Present invention also offers a kind of preparation method without asbestos seal gasket, comprise the following steps successively：It is batch mixing, close Refining, rolling slice, molding sulfidization molding；In the rolling slice step, vulcanizing agent is added simultaneously in the raw material after banburying Flaky material is rolled into mill；In the molding sulfidization molding step, by the flaky material in vulcanizing press mould 185-200 DEG C is heated in tool, pressurize 10-15MPa, hot-press solidifying 3-5 minutes makes the rubber component in material be solidified by rubber To produce no asbestos seal gasket after ripe glue.
The beneficial effects of the present invention are：
(1) it is of the invention without asbestos seal gasket with nitrile rubber (NBR) for adhesive substrate, aramid fiber is grain skeleton Material, the gap in aramid fiber and rubber is filled using precipitated calcium carbonate, mica powder, and pass through certain moduli pressure as inserts Sulfidization molding technique is made, with good sealing property, high temperature resistant, and tensile strength and crushing resistance are strong, and resilience is high, applicable for temperature Spend for≤350 DEG C, pressure≤10.0MPa.
(2) banburying process is rotated using high speed centrifugation, the aramid fiber in sizing material can be made to be uniformly dispersed, not lump, fully With rubber adhesion, the present invention instead of traditional handicraft using banburying process to carry out immersion swelling treatment with solvent " benzene ", simply Effectively, while reducing environmental pollution and the injury to producers.
(3) traditional rolling process is replaced to produce with plane mould die pressing, compared with rolling technology, the material thickness being made Uniformity tolerances are small, while pressure is balanced, product quality stabilization, precision height, the standardization level of production are high.
Embodiment
With reference to specific embodiment, the present invention will be described in detail, and the description of this part is only exemplary and explained Property, there should not be any restriction effect to protection scope of the present invention.
One kind of the present invention includes the raw material components of following parts by weight without asbestos seal gasket：
Preferably, no asbestos seal gasket, percentage includes following raw material components：
A kind of preparation method as described above without asbestos seal gasket, comprises the following steps successively：Batch mixing, banburying, rolling Extrude piece, molding sulfidization molding；In the rolling slice step, vulcanizing agent is added in the raw material after banburying and in mill Flaky material is rolled into machine；In the molding sulfidization molding step, by the flaky material in plate vulcanization machine die plus Heat arrives 185-200 DEG C, and pressurize 10-15MPa, and hot-press solidifying 3-5 minutes makes the rubber component in material be cured as ripe glue by rubber After produce no asbestos seal gasket.
Embodiment 1：Without asbestos seal gasket
The raw material of the present embodiment is constituted：
The preparation method without asbestos seal gasket is：
(1) each component raw material is measured by formula；
(2) batch mixing：By each component raw material measured, all input is mixed 5 minutes into batch mixer, and is stirred；
(3) banburying：Raw material after batch mixing is put into banbury, at a high speed rotation banburying, by the aramid fiber in raw material With rubber adhesion；
(4) slice is rolled：Material after banburying is put into mill, and is put into vulcanizing agent simultaneously, is rolled in mill Extrude flaky material；
(5) it is molded sulfidization molding：Flaky material is delivered and is heated to 185 DEG C into plate vulcanization machine die, is forced into 15MPa, hot-press solidifying 5 minutes makes the rubber component in material turn into ripe adhesive curing by rubber, then takes out plate trimming for forming Produce no asbestos seal gasket.
Embodiment 2：Without asbestos seal gasket
The raw material of the present embodiment is constituted：
The preparation method without asbestos seal gasket is：Be the same as Example 1, difference is：It is molded the bar of sulfidization molding Part is 200 DEG C of temperature, is forced into 10MPa, hot-press solidifying 3 minutes.
Embodiment 3：Without asbestos seal gasket
The raw material of the present embodiment is constituted：
The preparation method without asbestos seal gasket is：Be the same as Example 1.Embodiment 4：Without asbestos seal gasket
The raw material of the present embodiment is constituted：
The preparation method without asbestos seal gasket is：Be the same as Example 1.
Embodiment 5：Without asbestos seal gasket
The raw material of the present embodiment is constituted：
The preparation method without asbestos seal gasket is：Be the same as Example 1.
Embodiment 1-5 is subjected to tensile property, compression ratio without asbestos seal gasket respectively, returned
Bullet rate, load-carrying compressive property etc. are tested, and its result data is as shown in table 1：
Table 1
Described above is only presently preferred embodiments of the present invention, not to the technology model of the present invention
Enclose and make any limitation, therefore any trickle repairing of being made to above example of every technical spirit according to the present invention Change, equivalent variations and modification, still fall within the range of technical scheme.
