Abstract

The invention discloses a hollow inflation-free plastic foaming wheel which is formed by carrying out low-temperature pelletizing on a composition, carrying out low-temperature injection-molding on the composition by use of an injection molding machine to form wheel blank, and putting the wheel blank into a mould to carry out high-temperature foaming, wherein the composition comprises the following components in parts by weight: 55-60 parts of ethylene-vinyl acetate (EVA), 20-30 parts of styrene-butadiene (SBS), 15-25 parts of rubber softening oil, 10-20 parts of calcium carbonate, 15-25 parts of polyethylene (PE), 2-4 parts of an AC foaming agent, and 1-2 parts of dicumyl peroxide (DCP). The hollow inflation-free plastic foaming wheel has the advantages that the weight is relatively great, the sense of weight is strong, and the visual sense has sense of rubber; and more importantly, on usability, the wear resistance can be improved by 2.5 times, the carrying capacity can be improved by 3-4 times, the skid resistance is greatly improved, and the service life can be prolonged by more than three times.

Description

Hollow exempts from inflation plastic cement foaming wheel
Technical field
The present invention relates to a kind of tire, relate in particular to foamed plastic wheel, is specifically that a kind of hollow exempts from inflation plastic cement foaming wheel.
Background technology
Hollow is exempted from inflation plastic cement foaming wheel and is mainly used in the riding roller such as movable small generator, grass mower, carriage for children, Mini type trailer.Existing conventional hollow is exempted from inflation plastic cement foaming wheel and is mainly adopted ethene-vinyl acetate (EVA) to be main raw material, adds whipping agent, carries out low temperature granulation, then its low temperature is injection molded into wheel blank with injection moulding machine and puts into mould and form through high temperature foaming.This tire due to light, the intermolecular structural capacity of its material poor, show not only lightweight, there is no rubber texture, poor flexibility and do not have rebound resilience, more importantly its use properties exists wear no resistance, wear and tear large, bearing capacity is little, anti-skid is poor, product is short for work-ing life.
Summary of the invention
The technical problem to be solved in the present invention is, defect and the deficiency of inflating the existence of plastic cement foaming wheel skill is exempted from for above-mentioned existing hollow, there is provided that a kind of wear resistance is strong, wear rate is little, bearing capacity is large, non-skid property is good, the hollow of long service life exempts from inflation plastic cement foaming wheel.
Technical solution of the present invention is:
A kind of hollow exempts from inflation plastic cement foaming wheel, mainly carries out low temperature granulation by following composition, then with injection moulding machine, its low temperature is injection molded into wheel blank, then wheel blank is put into mould and form through high temperature foaming, and said composition includes by its ratio of weight and number:
Ethene-vinyl acetate (EVA) 55-60 part; Stupid ethylene-butylene (SBS) 20-30 part; Rubber softening oil 15-25 part; Calcium carbonate 10-20 part; Polyethylene (PE) 15-25 part; AC whipping agent 2-4 part; Dicumyl peroxide (DCP) 1-2 part.
As further improvement and the optimization of technique scheme, described composition is respectively by its ratio of weight and number:
Ethene-vinyl acetate (EVA) 58 parts; Stupid ethylene-butylene (SBS) 26 parts; Rubber softening oil 20 parts; 15 parts, calcium carbonate; Polyethylene (PE) 20 parts; AC whipping agent 3 parts; Dicumyl peroxide (DCP) 1.5 parts.
The present invention has the following advantages: the hollow processed according to the above-mentioned disclosed composition production of the present invention is exempted from inflation plastic cement foaming wheel and existing conventional hollow and exempted to inflate compared with plastic cement foaming wheel: its heavier mass, deal sense is strong, vision has rubber sense, the more important thing is in its use properties, wear resistance can improve 2.5 times, load-carrying can promote 3-4 doubly, and anti-skid improves greatly, and work-ing life can extend more than 3 times.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
A kind of hollow exempts from inflation plastic cement foaming wheel, low temperature granulation is carried out primarily of following composition, with injection moulding machine, its low temperature is injection molded into wheel blank again, wheel blank is put into mould to form through high temperature foaming, said composition is respectively by its parts by weight: ethene-vinyl acetate (EVA) 55-60 part, stupid ethylene-butylene (SBS) 20-30 part again, rubber softening oil 15-25 part, calcium carbonate 10-20 part, polyethylene 15-25 part, whipping agent (AC whipping agent) 2-4 part; Dicumyl peroxide (DCP) 1-2 part.Its preparation process is, the first step, stupid ethylene-butylene (SBS) and rubber softening oil are inserted in 90 DEG C of stirrers and carry out about within 10 hours, being uniformly mixed, rubber softening oil is made fully to immerse in stupid ethylene-butylene, then calcium carbonate and polyethylene are added and proceed to stir, after stirring, then carry out extruding pelletization with two spiral shell forcing machine; Second step, by the granules of the first step and ethene-vinyl acetate in stirrer after mixing and stirring, adds AC whipping agent and dicumyl peroxide stirs again, then stirring thing is inserted forcing machine and carry out low temperature extruding pelletization; 3rd step, is injection molded into wheel blank by micelle injection moulding machine by its low temperature, the 4th step, and the wheel blank of the 3rd step is put into foaming machine and take turns die cavity and carry out high temperature foaming, temperature general requirement is at 230 DEG C-250 DEG C; 5th step, the demoulding, cooling become finished product.
Embodiment one
