Description

A kind of long-life uniform elastic trampoline
Technical field
The invention belongs to trampoline and for the elastic trampoline cloth field of trampoline.
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 deficiencies: the frame body of 1. trampolines Product is larger, thus after manufacturer produces bouncer products, each assembled trampoline has sizable volume, Finished product is not only stored up in factory can occupy the confined space in factory, and when export trade also will increase transportation cost, furthermore, no matter exhibition sale Shop or personal use person, trampoline be intended to occupy sizable interior space without using under state.2. current trampoline is adopted It uses spring as its elastic force source, for the sake of security, needs to be laid with neonychium above spring, avoid unexpected generation.So This neonychium needs to increase the cost of trampoline；Built-up time is increased, simultaneously as spring can generate flexible deformation, it is former Neonychium is tightly to cover, but after the flexible deformation of spring, neonychium can deviate, and cause to cover when this is not used Lid is uneven and exposes spring, so as to will increase the incidence of safety accident.3. again due to being using spring as elasticity Part is covered using neonychium and is laid with, greatly reduces effective usable floor area of trampoline, the reality of trampoline has been limited in the presence of spring It jumps space.The problems such as elastical cloth of trampoline in the prior art, service life is short, cloth cover uniform elastic is poor.
Summary of the invention
To solve the above-mentioned problems, technical scheme is as follows:
A kind of long-life uniform elastic trampoline, it is characterised in that: including frame, elastic trampoline cloth and protective net, the frame Frame includes bottom frame and the foot lever that is installed below bottom frame.
Elastic trampoline cloth is double-layer structure, and one layer is resilient material made of nylon fiber, and another layer is cellulose fiber Manufactured material strips are tieed up, are combined between two layers by high polymer elastic layer；Every layer all from through elastic to elastic webbing and broadwise Band composition, it is described through being diamond shape to the gap between elastic webbing and broadwise elastic webbing；The gap is 10 to 25 squares of millis Rice；It is described through being 2-5 millimeters to the spacing between elastic webbing；Spacing between the broadwise elastic webbing is 3-6 millimeters；Institute The high polymer elastic layer stated includes at least thermoplastic elastomer (TPE) or thermo-setting elastomer using high polymer elastic material；Its Middle thermoplastic elastomer (TPE) includes thermoplastic, Polyurethane, polyvinyl chloride；Thermo-setting elastomer then includes silica gel.The Buddhist nun Imperial resilient material have passed through anti-aging processing, processing step are as follows:
1) 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- Amino -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 simultaneously by several times Reducing agent thiourea dioxide is added, is cooled to room temperature after reacting 0.5 ~ 3h at 75 ~ 80 DEG C, sulfuric acid is added and adjusts pH value 5 Between~6, filtering, dry in the shade, re-dry after recrystallization obtains functional modifier crude product, then by functional modifier crude product, Hydrofluoric acid and concentrated nitric acid are added in reaction vessel, and after being heated to 45 ~ 50 DEG C of 1.5~2.0h of reaction, Off-white product is obtained by filtration, It is filtered through cooling, dries in the shade, recrystallize and dry, obtain age resister；
2) preparation of anti-ageing microcapsules and age resister finishing fluid
