Description
Technical field
The invention belongs to sealing material technical fields, and in particular to a kind of refractory seals adhesive tape.
Background technique
Vacuum forming technique needs for product to be sealed between mold and vacuum bag, is pressurizeed, is made to product by vacuumizing
Product is more closely knit, mechanical property is more preferable.During vacuum bag transfer moulding method is implemented, needs to seal using vacuum bag and take out
Adhesive tape is needed to be sealed between vacuum bag and vacuum bag between vacuum, i.e. vacuum bag and production mold, due to using
The process that heating is had in journey makes molding machine be in the condition of high temperature, and the adhesive tape as sealing is required to have centainly at this time
High temperature resistance；Meanwhile for convenience of industrial operation, it is desirable that in demoulding, sealed colloid will not have residual on mold.But
It is that sealant used at present can usually be destroyed because of excessively high temperature, generates cracking at high temperature, trickling influences very
The sealing performance of empty bag, when demoulding again more than the residue glue due to increase the clean burden of mold.
Summary of the invention
The present invention proposes a kind of refractory seals adhesive tape, which has good high temperature resistance, also have certain
Flame retardant property, tack is also fine.
The technical proposal of the invention is realized in this way：
A kind of refractory seals adhesive tape, according to the number of parts by weight, including following components：
15~30 parts of matrix resin, 40~60 parts of inorganic filler, 2~8 parts of vulcanizing agent, promotees 10~20 parts of high temperature resistant auxiliary material
Into 1~4 part of agent and 3~10 parts of tackifier；The high temperature resistant auxiliary material is mainly matrix, graphene oxide by nano magnalium hydrotalcite
As auxiliary agent, hot pressed sintering is formed under the conditions of 250 DEG C~350 DEG C.
Preferably, the preparation method of the high temperature resistant auxiliary material includes the following steps：
(1) nano magnalium hydrotalcite is put into ethanol solution and is carried out, stirred simultaneously ultrasonic disperse, obtain dispersion liquid A；
(2) graphene oxide is weighed in proportion, ultrasonic disperse in the acrylic emulsion of n,N-Dimethylformamide is added, obtain
To dispersion liquid B；
(3) organic binders solvent is added after mixing dispersion liquid A with dispersion liquid B, grinding is sufficiently mixed, then at 250 DEG C
~350 DEG C of condition pressure sintering sintering, can be obtained high temperature resistant auxiliary material.
Preferably, the mass ratio of the graphene oxide and the nano magnalium hydrotalcite is 5~15:100.
Preferably, the organic binders solvent is PVB and isopropanol according to weight ratio is 1:1 ratio mixes.
Preferably, it according to mass ratio is 3~5 that the matrix resin, which is butyl rubber and ethylene propylene diene rubber,：1 combination mixes
Close object.
Preferably, the inorganic filler be selected from one of nanometer calcium carbonate, fumed silica and gas-phase silica or
Person is a variety of.
Preferably, the vulcanizing agent is selected from one or more of sulphur, stearic acid, magnesia and zinc oxide.
Preferably, the promotor is diphenylguanidine, dibenzothiazyl disulfide, tetramethylthiuram disulfide, tetrabenzyl
One or more of two thio thiurams, N- cyclohexyl -2- benzothiazole sulfonamide.
Preferably, the tackifier are one or more of rosin, Petropols and phenolic resin.
The preparation method of refractory seals adhesive tape of the invention：
1) it is spare that matrix resin, high temperature resistant auxiliary material, inorganic filler, vulcanizing agent, promotor and tackifier are weighed according to the proportion,
Matrix resin, high temperature resistant auxiliary material and inorganic filler are added in mixer, the mixing at 60~100 DEG C；
2) smelting temperature of step 1) is down to room temperature, vulcanizing agent, tackifier and promotor is added, gone out after being sufficiently mixed
Material；
3) material to discharge in step 2) is subjected to tabletting, cuts into item.
Beneficial effects of the present invention：
The present invention uses mainly by nano magnalium hydrotalcite for matrix, and graphene oxide is as auxiliary agent, 250 DEG C~350
High temperature resistant auxiliary material made of hot pressed sintering under the conditions of DEG C can be mentioned in the case where not influencing sealing joint strip tack and density
The high temperature resistance of highly dense seal strip, high temperature resistance reach 240~280 DEG C.In addition, can be improved the resistance of sealing joint strip simultaneously
Fire performance.

(2) graphene oxide is weighed in proportion, ultrasonic disperse in the acrylic emulsion of n,N-Dimethylformamide is added, obtain
To dispersion liquid B；The mass ratio of graphene oxide and nano magnalium hydrotalcite is 12:100.
(3) organic binders solvent is added after mixing dispersion liquid A with dispersion liquid B, grinding is sufficiently mixed, then at 250 DEG C
~350 DEG C of condition pressure sintering sintering, can be obtained high temperature resistant auxiliary material.
Test example
The refractory seals adhesive tape that embodiment 1-4 is obtained carries out tack and high temperature resistance is tested, and the results are shown in Table 1.
Tack：Referring to the initial viscosity of GB/T4852-2002 standard method test sealing joint strip, it is desirable that tack range
For 20~60mm.
Heat-resisting quantity test：Sample is put into oven for baking 2h.Concrete operations are：Test sample is resistance to since 240 DEG C
It is high temperatures, if there is colloid embrittlement, trickling phenomenon, from mold removing have residue glue when, then cool the temperature to next shelves after
Continuous test when embrittlement, trickling phenomenon do not occur for colloid, while can integrally be removed from mold, and when residual silkgum content≤1%, then
It is considered as test passes.Test temperature is with every 5 DEG C for a gear.The residue glue weight=(glue stripped down after initial weight-test
Weight) * %/initial weight.
