Abstract
The invention discloses a high-stiffness hatschek-process sealing material and a preparation technology. The high-stiffness hatschek-process sealing material is prepared from 15%-35% of fibers, 10%-20% of nitrile rubber, 5%-15% of rubber with the Tg value larger than 20 and 40%-70% stuffing. The preparation technology of the high-stiffness hatschek-process sealing material comprises the steps that the fibers and the stuffing are mixed to be uniform in a slurrying barrel, 5%-10% of aluminum sulfate is gradually added under stirring, and the materials are stirred to be uniform to form mixed liquid A; the rubber with the Tg value larger than 20 is diluted by adding water until the concentration is 5%-20% to form diluted rubber liquid, the diluted rubber liquid is added into the mixed liquid A to be uniformly mixed with the mixed liquid A, then a compounding agent of which the using amount accounts for 5% of the rubber with the Tg value larger than 20 is added, and uniform stirring is performed to form slurry; the pH of the slurry is regulated to be 7.5-9 through a 20% sodium hydroxide or potassium hydroxide solution after combination of the fibers and the stuffing is completed, and then the slurry is placed on a net to form the high-stiffness hatschek-process sealing material.
Description
Technical field
The present invention relates to encapsulant technical field, be specifically related to high-stiffness and copy close method encapsulant and preparation work
Skill.
Background technology
About copying the deflection problem following the example of encapsulant, it is presently mainly by feed change proportioning and promotes close
The methods such as the density of closure material are improved.But the method for feed change proportioning needs to carry out substantial amounts of experiment
Checking, process is loaded down with trivial details, and existing product can not carry out the lifting of deflection, because the change of proportioning is also
Being exactly the change of formula, final products performance will change.The lifting of density then can be covert increase
The cost of product, and after a certain product density reaches certain value, wanting to continue to increase its density is very
Difficulty.
Summary of the invention
For above-mentioned deficiency of the prior art, the high-stiffness that the present invention provides copies close method encapsulant and preparation
Technique is more than the addition of the rubber of 20 by Tg value, and in the case of not changing encapsulant, its deflection is but
Improve with having obtained amplitude.
In order to reach foregoing invention purpose, the technical solution used in the present invention is:
First aspect, it is provided that a kind of high-stiffness copies close method encapsulant, wherein encapsulant each formula and
Proportioning is: rubber more than 20 of fiber 15～35%, nitrile rubber 10～20%, Tg value 5%～15% and fill out
Material 40～70%；Wherein, each formula and the proportioning thereof of filler is: wollastonite 35～50%, Pulvis Talci 15～30%
With calcium carbonate 30～40%.
Second aspect, high-stiffness copies the preparation technology of close method encapsulant and comprises the following steps:
The mix homogeneously in cement slurry preparing barrel by fiber and filler, is the most under agitation gradually added into the sulphuric acid of 5%-10%
Aluminum, stir formation mixed liquor A；
Form rubber diluent after the Tg value rubber more than 20 is diluted with water to concentration 5%-20%, afterwards will
Rubber diluent adds in mixed liquor A after mix homogeneously, and adding consumption is the Tg value rubber 5% more than 20
Compounding ingredient stir formation slurry；
After fiber and filler have combined, the sodium hydroxide with 20% or potassium hydroxide solution regulation slurry pH
To 7.5-9, then online forms high-stiffness and copies close method encapsulant.
The invention have the benefit that this programme passes through to add the rubber of relatively high glass transition temperature, this rubber by
It is electronegative in itself, then crosslinks reaction, instead by positive charge aluminum ions in aluminum sulfate
While Ying, fiber and filler be wrapped up wherein.When the slurry prepared is copied and is taken molding entrance drying section, with
The rising of baking temperature, after the moisture in page gradually volatilizees, this rubber just starts gradually to harden,
And the deflection of encapsulant finally can be made at least to lift up to 50%, the intensity of encapsulant also obtains significantly
Degree improves, and can also ensure that other physical properties of encapsulant are unaffected simultaneously.
