Abstract
The invention relates to a dip solution and application thereof in aramid fibers. Because two-bath dipping is adopted, two-bath dip solutions are prepared; a first-bath dip solution comprises the following components: blocked isocyanate, an epoxy resin, a wetting agent and soft water; and a second-bath dip solution comprises the following components: resurcinolformaldehyde, vulcanized rubber powder, carbon black, water and zinc oxide. The aramid fibers treated by the dip solutions has high adhesive strength retention rate and slow adhesive strength attenuation.
Description
Technical field
The present invention relates to the dipping solution technical field, especially relate to a kind of dipping solution and the application in aramid fiber thereof.
Background technology
Aramid fiber is a kind of novel high-tech synthetic fiber, mainly is divided into contraposition aramid fiber (PPTA, Fanglun l414) and asks an aramid fiber (PMIA, aramid fiber 1313).Aramid fiber has superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, premium properties such as in light weight; Its intensity is 5～6 times of steel wire; Modulus is steel wire or glass fibre 2--3 a times, and toughness is 2 times of steel wire, and weight is merely about 1/5 of steel wire; Heat resistance is good, and the back strength retention that is heated is high.In addition, aramid fiber also has good insulation performance property and ageing resistace, and its invention is considered to a milestone in high-performance fiber field; Through development in recent years.The advantage of aramid fiber impregnation framework material more and more clearly be presented on the insider in face of.
Therefore but the structure of aramid fiber has upright and outspoken macromolecule and high crystallinity, makes its surface-activity low, can't expect to produce high adhesion strength between it and rubber.Therefore need carry out surface treatment to aramid fiber.Domestic (the RFL+ adhesive RP) maceration extract that always adopts carries out impregnation process to the aramid fiber framework material, and it is simple that this method has technology, and advantages such as establishing each is flooded in an existing bath capable of using; But the aramid fiber framework material of dipping is along with the prolongation in storage time; Its bonding strength attenuation ratio is very fast; The bonding strength conservation rate that particularly makes moist after drying again is lower, for making full use of the excellent properties of aramid fiber, is necessary aramid fiber two-bath process impregnation processing method row is studied.
Summary of the invention
The present invention is to provide a kind of bonding strength conservation rate high, dipping solution that the bonding strength decay is slow and the application in aramid fiber thereof for solving the problems of the technologies described above.
The technical problem that the present invention solved adopts following technical scheme to realize:
A kind of dipping solution,
The component of first bath comprises:
The sealing isocyanide ester
Epoxy resin
Wetting agent
Soft water
The component of second bath comprises:
Resorcinol formaldehyde latex (RFL liquid)
Vulcanized rubber powder (RP)
Soft water
Carbon black
Water
Zinc oxide
Wherein the resorcinol formaldehyde latex is made up of following component:
Soft water
Butadiene-vinylpyridine copylymer latex
Resorcinol formaldehyde resin liquid (RF liquid)
After these components were mixed, slaking 20-40h re-used;
Wherein resorcinol formaldehyde resin liquid (RF liquid) is made up of following component:
Soft water
Resorcinol
Formic acid
NaOH
These components are mixed back placement 4-10h and are re-used.
Further, said dipping solution comprises the component of following weight portion:
The component of first bath comprises:
The component of second bath comprises:
Wherein the resorcinol formaldehyde latex is made up of following component:
After these components were mixed, slaking 20-40h re-used;
Wherein resorcinol formaldehyde resin liquid is made up of following component:
These components are mixed back placement 4-10h and are re-used.
Further, said dipping solution comprises the component of following weight portion:
The component of first bath comprises:
The component of second bath comprises:
Wherein the resorcinol formaldehyde latex is made up of following component:
After these components were mixed, slaking 20-40h re-used;
Wherein resorcinol formaldehyde resin liquid is made up of following component:
These components are mixed back placement 4-10h and are re-used.
Above-mentioned dipping solution is used to flood aramid fiber and makes impregnation aramid fiber cord fabric or impregnation aramid fiber rope etc.
A kind of method of using above-mentioned dipping solution dipping aramid fiber comprises:
(1) getting aramid fiber soaks in first bath;
(2) with the water-bath 20-25 ℃ immersion in second bathes of the aramid fiber after the above-mentioned immersion, oven dry after soaking.
Further, the soak time of said first bath is 4-6h, and the soak time of second bath is 12-30h; Bake out temperature is 200-260 ℃.
Because the toughness and the fatigue durability of aramid fiber are poor; The first bath maceration extract of aramid fiber cotton rope two-bath process should reduce not even with the impregnated material that reduces toughness; While must make the cotton rope behind the impregnation have good bonding effect again; For reaching the requirement of this two aspect, the first bath maceration extract of two-bath process is the water-based epoxy resin maceration extract; The second bath maceration extract is the RFL maceration extract; Find through experiment: it is to make moist after the oven dry again to the adhesive activated aramid fiber long filament cotton rope bonding strength of two-bath process dipping than the high sorrow of adhesive activated aramid fiber long filament cotton rope of single bath process dipping; The bonding difference of cotton rope of two kinds of dipping method preparations is more obvious; The adhesive activated aramid fiber long filament cotton rope bonding strength of two-bath process dipping is 91.2% before making moist; Before the adhesive activated aramid fiber long filament cotton rope of single bath process dipping then is reduced to and makes moist 62.4% only is the adhesive activated aramid fiber long filament cotton rope 62.6% of the sticking test usefulness of two-bath process dipping, and therefore the adhesive activated aramid fiber long filament cotton rope with the two-bath process preparation is more suitable for storage.
