Product.
Below to provided in an embodiment of the present invention with a kind of heat-barrier material, preparation method and coating processes for fabric
It is specifically described.
An embodiment of the present invention provides a kind of heat-barrier materials for fabric, are prepared by plurality of raw materials, Duo Zhongyuan
Material includes 1-4 parts of unifor, 3-12 parts of trishydroxymethylaminomethane, 0.2-1.5 parts of activator, crosslinking agent 0.1-0.8
10-20 parts of part, 0.2-1.5 parts of polycarboxylate sodium, 60-80 parts of polyurethane resin and toluene.
It should be noted that molten by phase-change material trishydroxymethylaminomethane, organic foaming agent unifor, oil
Property dispersant polycarboxylate sodium compounding, and composite functional material and polyurethane resin and toluene are formed into intumescent coating slurry,
It is easy to form coating on the fabric, plays heat-insulated effect.Inventor's discovery, trishydroxymethylaminomethane, tolysulfonyl
The compounding effect of hydrazine and polycarboxylate sodium are very ideal, the small-sized and unit area of abscess in finally formed intumescent coating
There are many interior abscess number, this may exactly cause heat-barrier material provided in an embodiment of the present invention formula be applied to fabric after every
Where the good reason of thermal effect.Polyurethane foam and fabric can further be promoted by introducing activator and crosslinking agent in formula
Between bonding intensity, increase the service life of barrier fabric.
Trishydroxymethylaminomethane is a kind of polyalcohol phase-change material of high storage capacity, and inventor is mainly by by three hydroxyl first
Base aminomethane carries out compounding with foaming agent and dispersant and promotes final heat-proof quality.Wherein, organic foaming agent is to toluene sulphur
Hydrazides has great influence for the effect of foaming, is conducive to generate the small abscess of size, and reduce the spacing between abscess.Point
It is more uniform that powder polycarboxylate sodium makes trishydroxymethylaminomethane and unifor be distributed, and makes whole heat-insulated after processing
Performance is very excellent.
The heat insulation after fabric is handled in order to further enhance heat-barrier material, inventor is further to each group in formula
The dosage divided is optimized.Preferably, plurality of raw materials includes 1.5-3 parts of unifor, trishydroxymethylaminomethane 5-
10 parts, 0.5-1 parts of activator, 0.2-0.5 parts of crosslinking agent, 0.5-1 parts of polycarboxylate sodium, 60-75 parts of polyurethane resin and toluene
12-20 parts；It is highly preferred that unifor is 1.5-2 parts, trishydroxymethylaminomethane is 6-8 parts, activator 0.5-1
Part, crosslinking agent are 0.2-0.5 parts, polycarboxylate sodium is 0.6-0.8 parts, polyurethane resin is 64-70 parts and toluene is 13-18
Part.
It should be pointed out that trishydroxymethylaminomethane, unifor and polycarboxylate sodium in inventive formulation
Proportioning needs strictly controlled, the dosage of three is more notable on heat insulation influence.Wherein, trihydroxy methyl amino first
Alkane is main function material, and dosage is more, and the dosage of unifor and polycarboxylate sodium are taken second place, if tolysulfonyl
The dosage of hydrazine and polycarboxylate sodium increase or decrease the reduction that can lead to heat-proof quality.
Specifically, activator in ethylenediamine phosphate, dimethylbenzene, ammonium chloride and stearic acid salt any one or it is more
Kind；Preferably, activator is stearic acid salt.The addition of activator can further promote foaming effect, reduce abscess-size and
Spacing.Inventor has found, activator uses stearate, such as odium stearate, potassium stearate, for abscess improvement most
It is good.
Specifically, crosslinking agent is selected from cumyl peroxide, benzoyl peroxide, -4 methylimidazole of 2- ethyls, 2- isopropyls
Any one or more in base imidazoles and polyisocyanates；Preferably, crosslinking agent is polyisocyanates.The addition of crosslinking agent is only
If improving the bonding intensity of heat insulating coat and base fabric, the service life of barrier fabric is promoted.In above several crosslinking agents
In, the best results of polyisocyanates, the heat insulation of heat insulating coat is still very ideal after long-time use.
The embodiment of the present invention additionally provides a kind of preparation method of the heat-barrier material for fabric, and fabric is used for above-mentioned
Heat-barrier material formula be raw material, specifically include following steps：By unifor, trishydroxymethylaminomethane, activation
Premixed slurries are obtained after agent, crosslinking agent, polycarboxylate sodium and toluene mixing；Premixed slurries are mixed with polyurethane.
It should be pointed out that the dosage for each component in the preparation method of the heat-barrier material of fabric follows above-mentioned heat-insulated material
Dosage in material formula, first by unifor, trishydroxymethylaminomethane, activator, crosslinking agent, polycarboxylate sodium and first
After benzene mixes in mixing machine, then with solvent borne polyurethane it is mixed with to obtain intumescent coating slurry.Entire preparation method is easy easily
Row, is very suitable for industrial applications.
Preferably, it is 250-350rpm that rotating speed is controlled in the preparation process of premixed slurries, in premixed slurries and is gathered
It is 900-1100rpm that rotating speed is controlled in urethane mixed process.The rotating speed of stirring blade is adjusted in mixed process twice
Control, first mix when need relatively slowly stirring so that main function material in toluene be uniformly mixed, then again with
Polyurethane mixes in high-speed stirred, this is mainly and the viscosity of raw material has certain relationship, the mixing of polyurethane to be more suited to adopt
It can be only achieved uniformly mixed effect with the Blending Processes of high speed.
The embodiment of the present invention additionally provides a kind of coating processes of the heat-barrier material for fabric, including：By above-mentioned preparation
The heat-barrier material that method is prepared forms coating on the fabric by way of blade coating.
Specifically, the heat-barrier material prepared in the embodiment of the present invention can be coated on fabric by conventional coating processes
Upper formation heat insulating coat.
Preferably, coating processes include：The above-mentioned heat-barrier material being prepared is scratched, blade coating thickness is 1-5mm；
Fabric after blade coating is preheated into 15-25min under 140-160 DEG C of temperature condition, then cures 25- under pressure
35min is cooled to room temperature.
It should be pointed out that invention finds the painting formed when the heat-barrier material provided in the embodiment of the present invention is applied to fabric
The adhesion strength that layer can reduce coating with substantially 1-5mm, overweight coating influences service life, and cover light can lead to heat-insulated effect
Fruit is undesirable.Resolidification is conducive to promote cured effect after heat-barrier material first preheats.
Specifically, the pressure applied during cure under pressure is 0.55-0.65MPa, is increased during cure under pressure
Solidifying pressure is conducive to accelerate solidification process, shortens hardening time, and the coating uniformity formed is more preferable, and adhesion strength is also stronger.
Specifically, temperature in the curing process is controlled at 160-180 DEG C.Hardening time and solidification temperature mutual cooperation make
The uniformity of the coating of formation is good and strong adhesive force, inventor have found the solidification temperature of the heat-barrier material provided in the embodiment of the present invention
Degree needs to control at 160-180 DEG C, and solidification temperature is too high or too low all to reduce heat-proof quality to a certain extent.
Specifically, fabric is dacron or cotton fabric, and the heat-barrier material being prepared in the embodiment of the present invention is very suitable
It is highly desirable to the fabric heat-proof quality improvement of both materials together in applied to dacron and cotton fabric.
The feature and performance of the present invention are described in further detail with reference to embodiments.
