Abstract
The invention relates to a processing method of dumbbells, plates or similar instruments. The processing method is composed of a body and rubber sheets coated on the surface of the body; the body is produced with polyester concrete by the steps of molding and drying. In the method, non-wax pattern unsaturated polyester and non-wax pattern releasing agents are adopted as ingredients, so as to avoid the situation that the wax can be dissolved out and produce bubbles at the temperature of plastic dipping; a hot press molding process is adopted to form the instruments, thus leading the moisture contents in the skeletal materials to be fully volatilized, avoiding the moisture contents from being vaporized when in plastic dipping and overcoming the factor of producing the bubbles as well. Simultaneously, the hot press molding process is used, which can increase the compactness and intensity of the materials and can prolong the practical life of products.
Description
Technical field
The present invention relates to the processing method of dumbbell, disc or like instrument, relate in particular to a kind of processing method of making dumbbell, disc or like instrument by nonmetallic materials.
Background technology
Weight concrete also is high-density concrete, the main mode of producing weight concrete at present both at home and abroad is that the material such as the iron ore of big (about 6.0g/cm3) partly or entirely substitute gathering materials in the general goods concrete with density, improve concrete density, general density is greater than 2.8g/cm3.Now be widely used in the engineering position that engineering machinery, hoisting machinery, boats and ships, traffic, water conservancy and hydropower etc. need ballast, counterweight, and household electrical appliances, Body-building sandbag etc.Yet in the economic structure of current resource scarcity type, energy day is becoming tight, and price skyrockets, and can increase the production cost of weight concrete with the smart iron ore of costliness etc. greatly as concrete aggregate, reduces economic benefit of enterprises.In addition non-renewable iron ore being incorporated in the concrete itself is exactly a kind of great wasting of resources.Raising year by year along with China's metal smelt industry output, the discharge rate of smelting residue also increases thereupon, the smelting residue that accumulates in a large number not only causes huge pressure to the production of smelter with development, also become the pollution sources in city, a large amount of smelting residues all need the large tracts of land soil to stack every year, all bring serious pollution for soil, water body, atmosphere etc., even people's health is constituted a threat to.As long as a large amount of research practices show in addition suitable treatments utilization, and smelting residue promptly is a kind of resource.
In addition, building stones, ore charge, the slag of big density are not fully utilized in actual life, cause the waste of resource.Treasure glass fibre reinforced plastic factory, Jiangdu City, Jiangsu Province is in producing dumbbell, disc or like instrument process, adopt building stones, ore charge, the slag of big density and smelt aggregate making dumbbell, disc or the like instrument of residue, but in the product development process, find to exist some problems as goods.Such as, body is soaked mould processing after, many pores can appear in epidermis, have had a strong impact on the quality of product.
Summary of the invention
The present invention is directed to product surface in the prior art and the phenomenon of a large amount of bubbles can occur, provide a kind of can overcome to soak mould the rear surface cortex and the dumbbell of bubble, the processing method of disc occur.
The present invention is made of body and the rubber that is coated on body surface, and body is made through moulding, drying by polyester concrete, and described body is processed according to the following steps:
1), select the aggregate of density for use greater than 3.5 gram/cubic centimetres, be processed into 0.01～10 millimeter powder, piece, granular;
2), up adding no wax pattern unsaturated-resin, no wax pattern releasing agent, curing agent in the step aggregate evenly mixes and is polyester concrete; The weight ratio of no wax pattern unsaturated-resin, no wax pattern releasing agent, curing agent and aggregate is 8～15: 0.1～0.3: 0.08～0.15: 100;
3), mixed polyester concrete is added heat pressing and molding mold, the upper and lower mould temperature of heat pressing and molding mold is heated to 150～160 ℃, keeps the demoulding 10～90 seconds;
4), profiled member cooling, the cleaning surface makes body.
In described powder, piece, the granular aggregate size below 1 millimeter be 1: 2～10 greater than 1 millimeter part by weight smaller or equal to 8 millimeters.
Described aggregate is building stones, ore charge, slag.
Described aggregate is for smelting residue.
The present invention adopted no wax pattern unsaturated-resin, no wax pattern releasing agent in batching, avoided wax can separate out under the temperature and produce the situation of bubble soaking to mould; With the hot press forming technology moulding, the moisture in the aggregate is fully volatilized, avoided moisture content to mould time vaporization soaking, overcome the factor that produces bubble equally.Simultaneously, use hot-formingly, can increase the packing and the intensity of material, prolong the product physical life.
