Description
Technical field
The present invention relates to field of exercise equipment, more particularly to a kind of disc and its production technology.
Background technique
Barbell is a kind of necessary equipment of weight training, can promote shoulder, back, arm, chest using barbell exercising equipment
The training of portion etc. muscle strength will inevitably use rubber material in the production of barbell, in recent years petrochemical industry
Resource not reduce by section, and section is not soaring for natural gum and petrochemical industry synthetic rubber price, under this overall situation, to fitness equipment
Field generates enormous impact, especially generates havoc to the production of Lifting barbell product, and carrying out thick stick using rubber
It when bell produces, inevitably can cause environmental pollution, but environmental protection industry is all actively being developed in the whole world at present, advocates energy conservation
Emission reduction, therefore barbell production technology must be reformed, coping resources status in short supply complies with environmental requirement.
10248900 A of CN proposes a kind of method using making weight plate with renewable colloidal particles in the prior art, but its
The adhesive of use is Bi-component adhesive, complicated for operation cumbersome, is easy to appear adhesive curing agent number proportion inaccuracy, produces
The problems such as product solidification is not exclusively, barbell impact resistance reduces, adhesive premature setting generates the wasting of resources, and above-mentioned patent
Reinforced resin ingredient main component is phenolic resin, can bring a degree of pollution to environment in use process, influence entire
Ecological environment, the production of Phenolic resin powder can also generate a large amount of waste water and energy consumption, this is all managed with Green Development energy-saving and emission-reduction
Thought is disagreed, and phenolic resin also climb to a higher point successively therewith by petrochemical industry resource scarcity status, cost, causes barbell product price inclined
Height limits resident's body-building career development.
Therefore it is easy, at low cost and have the advantages that the disc of environmental protection and energy saving and its producer how to provide a kind of preparation process
Method is those skilled in the art's urgent problem to be solved.
Summary of the invention
In view of this, the present invention provides a kind of discs made of waste tire, and use the poly- ammonia of one-component
Ester adhesive is raw material, and not only energy conservation and environmental protection reduces cost, but also easy to operate and control.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of disc is made of the raw material of following components: rubber tire particles, adhesive；
The weight of the rubber tire particles and adhesive is 10:1-10:1.5.
Further, the adhesive is single-component polyurethane adhesive, is made of following weight ratio component raw material:
Toluene diisocynate or methyl diphenylene diisocyanate 60%-63%, ethyl acetate 20%-23%, 1,4- fourth
Glycol 5.5%-10.5%, dibutyl tin dilaurate 0.5%-1%, phthalic acid two (2- ethyl hexyl) ester 2%-3.5%.
Taking the beneficial effect of above-mentioned further technical solution is: single-component polyurethane adhesive is nontoxic, pollution-free, and
Using preceding without carrying out stoichiometry and adding other crosslinking agents, it is easy to operate and control, and the disc after solidify is with excellent
Good performance.
Preferably, the partial size of the rubber tire particles is 6-28 mesh, the granular size and single-component polyurethane adhesive
With optimal conjugation.
Preferably, the rubber tire particles be one of black rubber tyre crumbs, colorful rubber tyre crumbs or
Mixture can carry out collocation of colour according to production requirement, keep product more rich and varied.
It is a further object to provide a kind of preparation processes of disc, specifically use following scheme:
A kind of preparation process of disc, comprising the following steps:
(1) tire is crushed, obtains the rubber tire particles tentatively crushed；
(2) steel wire in the rubber tire particles tentatively crushed obtained in the step (1) is removed, mesh is then filtered out
Number is the rubber tire particles of 6-28 mesh；
(3) the various components of adhesive are weighed according to formula, reaction is mixed later, it is spare；
(4) by monocomponent polyurethane obtained in rubber tire particles obtained in the step (2) and the step (3)
Adhesive is mixed and is sufficiently stirred；
(5) by the rubber tire particles adhesive combination after being sufficiently stirred in the step (4) according to the quality of barbell
Demand is weighed, and places carry out primary solidification later；
(6) the rubber powder adhesive combination investment particular manufacturing craft after primary solidification in the step (5) is solidified；
(7) disc being cured in the step (6) is removed from the molds, repairs burr removing after placing cooling, the production
Product production terminates.
It preferably, can be quick using the steel wire inside superpower magnetic force devices removal rubber tire particles in the step (2)
The impurity such as efficient removal steel, guarantee the pure of rubber tire particles.
Preferably, reaction is mixed in the step (3) to carry out at normal temperatures and pressures, mixing is stirred in the step (4)
It mixes and carries out at normal temperatures and pressures, because single-component polyurethane adhesive can synthesize at normal temperatures and pressures, without additional energy consumption,
And response procedures are simply controllable.
Preferably, in the step (3) to spare adhesive saved under air-proof condition, avoid adhesive and air
In vapor and oxygen reaction occur moisture solidification and fail.
Preferably, solidified in the step (6) using heating machine, set temperature is 135-155 DEG C, pressure controlling 60-
100 megapascal keep the temperature 15-50 minutes.
In conclusion the opposite and prior art, the beneficial effects of the present invention are: using synthetic reaction can occur under room temperature
Nontoxic and pollution-free single-component polyurethane adhesive be raw material, no longer need to additionally add reinforced resin, adhesive use before
It need not carry out stoichiometry and add other crosslinking agents, so that preparation process is easy to operate and control, and use waste and old tire
Rubber grain is raw material, is had great importance to environmental protection and energy conservation, it is important that production cost is reduced, and
For disc tensile strength obtained up to 15 megapascal, shore hardness has excellent performance up to 80 degree.
