Description
Technical field
The present invention relates to the preparation method of fine chemicals, specifically, the present invention is a kind of method that is used to prepare the composition of dumbbell and prepares dumbbell with said composition.
Background technology
At present, the dumbbell used of body-building and the mass of body-building apparatus use cast iron materials for many years always.Cast iron dumbell needs pyrotic smelting in making processes, consume a large amount of energy and iron resources, and serious environment pollution do not meet the policy requirements of current country, and manufacturing process is loaded down with trivial details, the cost height.
Summary of the invention
The present invention has overcome above-mentioned shortcoming, has proposed a kind of method that is used to prepare the composition of dumbbell and prepares dumbbell with said composition.
Said composition also can be used for substituting other body-building apparatus that is got by cast iron.
Every index request of this material can satisfy the service requirements of body-building apparatus fully, the body-building apparatus of making of this material such as dumbbell have cast iron the advantage that can not compare, high economic benefit is arranged.
A kind of composition that is used to prepare dumbbell, form by the raw material of following weight part:
Trans isoprene (TPI), consumption 2-4 part;
EVA, consumption 5-8 part;
Iron ore powder, consumption 45-60 part;
Ground barium sulfate, consumption 45-60 part;
And performance auxiliary agent;
Wherein, described performance auxiliary agent is made up of following materials in weight portion:
Antioxidant 1010: consumption: 0.5wt%
Dispersion agent silicone grease ST-1013: consumption: 0.8wt%
Coupling agent A-151: consumption: 2wt%
Grafting softening agent: consumption: 5wt%;
Described weight percent is the per-cent that accounts for composition total weight.
Composition total weight is meant: the weight sum of these four kinds of basic materials of trans isoprene, EVA, iron ore powder and ground barium sulfate.
The preferential selection of grafting softening agent is dimethyl ester DOF.
Iron ore powder is a 150-300 purpose fine powder, and ground barium sulfate is a 200-300 purpose powder.
The method that above-mentioned composition prepares dumbbell is:
(1) activation iron ore powder and ground barium sulfate are processed into 150-300 purpose fine powder to iron ore powder, and wet concentration becomes the particle of iron content 50-70% composition, the drying of anhydrating; Ground barium sulfate is processed into 200-300 purpose powder, and drying is anhydrated; The iron ore powder and the ground barium sulfate that process are mixed, add coupling agent, make active ore powder.
(2) TPI, EVA, performance auxiliary agent are put into mixing tank in proportion, mix the adding forcing machine, use temperature 160-185 ℃, time 8-10 minute, reaction modifying becomes the high molecular polymer powder formula pellet of high viscosity, high impact, is characterized in filling the weighting material of 900-1200%.
(3) with organic polymer material 1 weight part, add active inorganic ore powder 9-12 weight part, 150 ℃ of use temperatures, pressure 12KG/ cubic centimetre was plasticated 15-20 minute, accurately was ground into " ETR " raw material.
(4) " ETR " material is used injection press, be squeezed into the body-building dumbbell of different shape or the mass of body-building apparatus with 150 ℃ temperature.
The present invention possesses following advantage:
(1) energy-conserving and environment-protective can be saved higher energy and material in process of production, and are free from environmental pollution, do not contain toxic substances such as heavy metal, recycling capable of circulation.
(2) proportion is bigger, and density is the 3-3.5g/ cubic centimetre, can satisfy the service requirements of family fitness equipment.
(3) cost is low, and making same utensil cost only has 60% of cast iron.
In sum, above characteristics can satisfy the requirement of making body-building apparatus, and have overcome the shortcoming of ironcasting severe contamination and power consumption, and the product of making has higher economic advantages.
