Description

Elastic composite cloth
The application is entitled a kind of permanent seal cooling elastic composite application No. is 2016106277820, the applying date For the divisional application of 20160803 application for a patent for invention.
Technical field
The invention belongs to elastic composite fields.
Background technique
It 2009 " Bedjump ", runs away rapidly on website, Chinese is translated into " trampoline " or " trampoline ".It is gathered around in all parts of the world There are numerous fans for growing tender of this movement.Fan would generally select the bed that elasticity is good, jump up, and make in the sky various dynamic Make.Trampoline is mainly equipped with a fabric tightened by most springs in the frame for the foot prop support that lands, and stands on for user Constantly spring carries out interest movement on spring face.Trampoline in the prior art has the following defects：1. the frame body of trampoline Product is larger, thus after manufacturer produces bouncer products, each assembled trampoline has sizable volume, no Finished product is only stored up in factory can occupy the confined space in factory, and when export trade also will increase transportation cost, furthermore, no matter the quotient of exhibition sale Shop or personal use person, trampoline are intended to occupy sizable interior space under without using state.2. current trampoline uses bullet Spring is as its elastic force source, for the sake of security, needs to be laid with neonychium above spring, avoids unexpected generation.It is so this Neonychium needs to increase the cost of trampoline；Built-up time is increased, simultaneously as spring can generate flexible deformation, is not made originally Used time neonychium is tightly to cover, but after the flexible deformation of spring, neonychium deviates, cause covering uneven and Expose spring, so as to will increase the incidence of safety accident.3. again due to being to utilize guarantor as elastic component using spring Protection pad covering is laid with, and greatly reduces effective usable floor area of trampoline, the space of actually jumping of trampoline has been limited in the presence of spring. Useful elastical cloth substitution spring in the prior art, but there are elastical cloth service lifes it is short, cloth cover uniform elastic is poor the problems such as.
Summary of the invention
To solve the above-mentioned problems, technical scheme is as follows：
A kind of permanent seal cooling elastic composite, it is characterised in that：Composite material is double-layer structure, wherein one layer anti-ageing to have carried out Change the resilient material arranged, arrangement process includes：1）The preparation of age resister；2）The preparation of microcapsules and finishing fluid；3）With The finishing fluid prepared carries out anti-aging arrangement to nylon elastic material strips.
Elastic composite cloth is double-layer structure, and one layer is resilient material made of nylon fiber, and another layer is fiber Material strips made of cellulose fiber are combined between two layers by high polymer elastic layer；Every layer all from through to elastic webbing and broadwise Elastic webbing composition, it is described through being diamond shape to the gap between elastic webbing and broadwise elastic webbing；The gap is 10 to 25 flat Square millimeter；It is described through being 2-5 millimeters to the spacing between elastic webbing；Spacing between the broadwise elastic webbing is 3-6 milli Rice；The high polymer elastic layer includes at least thermoplastic elastomer (TPE) or thermoset elastic using high polymer elastic material Body；Wherein thermoplastic elastomer (TPE) includes thermoplastic, Polyurethane, polyvinyl chloride；Thermo-setting elastomer then includes silica gel.It is described Nylon elastic material strips have passed through anti-aging processing, processing step is：
1）The preparation of age resister
Under nitrogen protection, by 3,4- chloro-2-methyl aniline or 2- naphthylamines or 4- amino -3,2- dimethyl azobenzene or 2- ammonia Base -4- nitrotoleune, is added in the water of the sodium hydroxide of 1.5 ~ 4 mol/L and the mixed solution of ethyl alcohol, stirs and adds by several times Enter reducing agent lithium aluminium hydride reduction, at 75 ~ 80 DEG C react 0.5 ~ 3h after be cooled to room temperature, be added sulfuric acid by pH value adjust 5~6 it Between, it filters, dries in the shade, re-dry after recrystallization obtains functional modifier crude product, then by functional modifier crude product, hydrogen fluorine Acid and concentrated nitric acid are added in reaction vessel, after being heated to 45 ~ 50 DEG C of 1.5~2.0h of reaction, Off-white product are obtained by filtration, through cold But it filters, dries in the shade, recrystallize and dry, obtain age resister；
2）The preparation of anti-ageing microcapsules and age resister finishing fluid
Using deionized water as solvent, in a solvent age resister dispersion, whipping temp is room temperature, controls whipping process medium-rate For 500~1000r/min, being dispersed with stirring the time is 50~65min, and age resister molecule is enable to form suspension in aqueous solution Then system adds hydroxyethyl cellulose and is dissolved, then carries out high-speed stirred dispersion, whipping temp is 35~40 DEG C, stirs Mixing rate is 3400~3600r/min, and mixing time is 10~15min, then adds butane tetracarboxylic acid and carries out chitosan friendship Connection, then curing 10min is carried out under the conditions of 85~90 DEG C, thick modified capsule is obtained by filtration, then be dried in vacuo at 60 DEG C After for 24 hours, the modification capsule containing age resister is obtained；Its sandwich layer is age resister, and cystoblast is hydroxyethylcellulose materials, wherein The thickness of cystoblast and sandwich layer ratio is 1: 18；By manufactured age resister microcapsules 3-6%（owf）, penetrating agent JFC 1-2g/l, pH value For 7-7.5, it is made into age resister finishing fluid；
The volume ratio of water and ethyl alcohol in the mixed solution of the water and ethyl alcohol is 1: 2；The lithium aluminium hydride reduction and 3,4- are chloro- The molar ratio of 2-aminotoluene or 2- naphthylamines or 4- amino -3,2- dimethyl azobenzene or 2- amino -4- nitrotoleune is 2: 1.5；The molar ratio 2: 2.2: 1.1 of the functional modifier crude product, hydrofluoric acid and concentrated nitric acid.
The age resister additive amount is 3.5-16% relative to the mass fraction of water；
The hydroxyethyl cellulose additive amount is 2.0-8% relative to the mass fraction of water；
The weight average molecular weight of the hydroxyethyl cellulose is 20000~25000, and molar substitution is 1.8~1.9.
The butane tetracarboxylic acid is 0.3% relative to the mass fraction of chitosan.
The diameter of modified capsule is 2~5 μm, is conducive to capsule and passes through spinneret orifice, and guarantees capsule and fiber Be firmly combined, the mechanical performance of fiber can't be influenced.
The capsule of modified capsule/core guarantees that microcapsules have certain mechanical strength and heat-resisting than being generally higher than equal to 1: 10 Property.
The effect of modified capsule is, plays the role of the anti-aging functional particles of slow release, is conducive to its anti-aging function Effect is able to permanent holding.
3）Anti-aging arrangement is carried out to nylon elastic material strips with the finishing fluid prepared.
Nylon elastic material strips are put into age resister finishing fluid and are impregnated, bath raio 1:It is soaked at 20-50,40 ~ 50 DEG C Stain 30-80 minutes, washing drying；Then the band arranged by age resister is pressed 1 with fixed liquid:The bath raio of 20-30 immerses solid In liquid, after permeating completely under room temperature, two leachings two are rolled, and pick-up 70-90% is dried in 80 DEG C, and 100-140 DEG C bake 2-3 points Clock is washed, is soaped, is dried；The composition of the fixation liquid includes glyoxal, magnesium chloride, tartaric acid and water, and concentration is 40% second Dialdehyde content in every liter of water is 20-50g, and magnesium chloride content in every liter of water is 2-5g, and tartaric acid content in every liter of water is 1-3g, the mixed liquor stirred evenly at room temperature.
