Description
Technical field
The invention belongs to garment material fields, and in particular to a kind of preparation method of fireproof facing material.
Background technique
Garment material is widely present and is applied in each of us life, most clothes, family's curtain etc.
Use textile cloth.
It is reinforced phase that garment material, which is fiber in a variety of manners, yarn, fabric, with resin, rubber, metal, cement, pottery
The materials such as porcelain are the composite material of matrix phase.The adhesion strength of the properity of garment material, textile material and basal body interface with
And the factors such as performance of matrix determine the performance of composite material.Garment material reinforcement is usually flexible body, and it is compound to weave
Material is either flexible body is also possible to rigid body.Due to the fiber in garment material, yarn or fabric can depending on the application and
Orientation, thus the anisotropic of textile reinforced composite material can be formed.
Current Process of Urbanization Construction makes people's lives more crypto set, no matter handles official business or lives, and many people live in same
In a building, number of floor levels is usually larger, and people rely more on elevator downstairs, very few for the understanding of exit passageway, general lack of
Knowledge on fire fighting, almost without escape experience.Occur fire when, people would generally be very terrified, exit passageway blocking, personnel be difficult and
When evacuate, cause great personal injury, property is difficult to save from damage, so, the injury of fire be it is extremely big, how to prevent fire
After calamity and fire occur, it is critically important how to eliminate fire.Currently, people there is no it is special, can be easily portable available
In fire service inventory, and now many chemical agent fire, electrical fire calamity, coal gas fire are not suitable for fire-fighting by water, so, it is right
In normal work and life, the people that can be helped without article put out a fire, and fire hydrant will also regularly replace, often be ignored or forgotten by people
Note.
In conclusion therefore, it is necessary to a kind of better fireproof clothes fabric, Lai Gaishan the deficiencies in the prior art.
Summary of the invention
For the problems of the prior art, the present invention provides a kind of preparation method of fireproof facing material, utilizes poly- aryl silicon tree
Fabric nonwoven cloth is carried out infiltration type and is modified by the high characteristic of the heat resistance of rouge, and formation is three-dimensional trapezoidal on fabric nonwoven cloth
Full phenyl polysiloxane is aided with the covering of fire proofing gross area, promotes whole fire protection flame retarding characteristic, while also having anti-electric waterproof
Characteristic.
To realize the above technical purpose, the technical scheme is that
A kind of preparation method of fireproof facing material, includes the following steps:
Step 1, low temperature in anhydrous ether is added in phenyl trichlorosilane to stir to being completely dissolved, obtains ether dissolution liquid;
Step 2, distilled water is added dropwise in diethyl ether solution, and seals low temperature ultrasonic dispersion 2-3h, then cooling is stood
To acidic hydrolysis liquid;
Step 3, fabric nonwoven cloth is dipped to acidic hydrolysis liquid middle-high density aeration reaction 2-5h, then lays nonwoven
Enter gradient-heated in reaction kettle and react 1-3h, obtains modification nonwoven cloth;
Step 4, flame-resistant coated liquid is coated uniformly on modification nonwoven cloth specific surface, drying obtains coating non-woven fabrics;
Step 5, mold high temperature is added in coating non-woven fabrics and squeezes polymerization reaction 3-6h, obtain fireproof facing material after cooling.
Concentration of the phenyl trichlorosilane in anhydrous ether in the step 1 is 20-50g/L, the stirring of low temperature stirring
Speed is 500-1000r/min, and the temperature of low temperature is 5-15 DEG C.
Distilled water additional amount in the step 2 is 5-10 times of phenyl trichlorosilane mole, rate of addition 1-
2mL/min seals the temperature of low temperature ultrasonic not higher than 20 DEG C, supersonic frequency 40-80kHz, and the temperature for the standing that cools down is 1-3
℃。
The aerating gas of high density aeration reaction in the step 3 is nitrogen, and aeration speed 15-30mL/min exposes
The entire fabric nonwoven cloth of gas area covering.
Gradient-heated in the step 3 includes following procedure:
Temperature | |
50-60℃ | 10-20min |
110-150℃ | Remaining time |
。
Coated weight in the step 4 is 1-5mL/cm2, drying temperature is 120-130 DEG C.
The temperature of high temperature extrusion polymerization reaction in the step 5 is 200-250 DEG C, squeeze pressure 2-3MPa.
The quality proportioning of the flame-resistant coated liquid is as follows:
2-5 parts of magnesium hydroxide, 10-20 parts of zinc oxide, 5-10 parts of powdery fluorocarbon resin, 10-15 parts of Fanglun slurry cake, ethylene glycol
5-10 parts, 20-40 parts of dehydrated alcohol.
Phenyl trichlorosilane is added into anhydrous ether step 1, using dissolubility of the phenyl trichlorosilane in ether,
The mode of cooperation low temperature stirring reaches being completely dissolved for phenyl trichlorosilane, at the same low temperature can reduce ether from volatility,
Ensure the integrality of ether dissolution liquid.
Distilled water is added dropwise in ether by step 2, and is formed quickly during being slowly added dropwise, and phenyl trichlorine silicon is obtained
The hydrolysate of alkane;Low temperature ultrasonic can be evenly dispersed into ether by distilled water, it is ensured that distilled water and phenyl trichlorosilane fill
Tap touching, promotes the percent hydrolysis of phenyl trichlorosilane;The mode of sealing low temperature ultrasonic is not brought merely with low temperature to reduce ultrasound
Thermal energy, prevent thermal energy from promoting bulk temperature, cause the condensation curing in advance of hydrolysate, and sealing can will be because of ultrasonic moment
Heat is generated, ether made of vaporization saves, and prevents it to scatter and disappear, causes the reduction of ether content, also reduce pollution;It is subsequent
Cooling, which is stood, to revert to ether liquid again for the ether of vaporization at low temperature.
Fabric nonwoven cloth is dipped in acidic hydrolysis liquid by step 3, is formed and is impregnated osmotic system, utilizes the good infiltration of ether
The adhesiveness of permeability and acidic hydrolysis object can adsorb the hydrolysate of a large amount of phenyl trichlorosilanes, together inside and outside fabric nonwoven cloth
When high density aeration reaction can accelerate ether to the infiltration inside fabric nonwoven cloth, while also reduce non-woven fabrics monofilament dredge
Fluidity promotes osmotic effect;Gradient-heated reaction is capable of forming Quadratic Pressure Gradient isothermal reaction, and the temperature of first gradient is fast by ether
Speed removal, while the hydrogen chloride dissolved in ether can also be removed, the phenyl trichlorosilane hydrolysate containing moisture is formed, the
Two gradients can quickly remove extra moisture, and promote phenyl trichlorosilane hydrolysate that polycondensation occurs using temperature action
Reaction obtains the full phenyl polysiloxane of outer cladding in non-woven fabrics improving the heat resistance of entire non-woven fabrics, it is good to assign non-woven fabrics
Good insulating properties and weatherability.
Flame-resistant coated liquid is evenly coated in nonwoven surface by step 4, forms flame-resistant coated layer, while flame-resistant coated liquid passes through
Pore on non-woven fabrics forms good infiltration, it is ensured that the tightness of non-woven fabrics;It can be quick by dehydrated alcohol in drying course
Removal, it is ensured that formed using ethylene glycol as the viscous fluid of solvent.
During high temperature extrusion, the rising of temperature can be formed ethylene glycol evaporates step 5, while magnesium hydroxide and oxygen
Change zinc as filler, Fanglun slurry cake and powdery fluorocarbon resin and cook resinoid bond, forms stable bond effect, be laid on nonwoven
Cloth surface forms fire-retardant fireproof layer, while squeezing the degree of packing that can increase fabric entirety.
From the above, it can be seen that the present invention has following advantages:
It is modified 1. fabric nonwoven cloth is carried out infiltration type using the high characteristic of the heat resistance of poly- aryl silicone resin by the present invention, and
