Abstract
The present invention discloses normal temperature superfine pulverization technology for plastics and rubber, which has the technological flow that after water is filled into a raw material, the raw material enters a high speed cutting grinder to be pulverized, and is filtered when the raw material is pulverized, and then, the raw material is dried and dispersed to obtain superfine plastic and rubber particles. The average particle diameter of the superfine plastic and rubber particles is smaller than 110 mu m. The present invention has the advantages of simple technology, low cost, small particle size of a finished product, simple operation and wide application range. A pulverization process does not need refrigeration, and is carried out under the normal temperature. The present invention is suitable for industrial production.
Description
The present invention relates to the disintegrating process of a kind of plastics, rubber type of material, particularly a kind of plastics, rubber normal temperature ultrafine grinding process.
In the prior art, chemical materials such as a large amount of plastics, school glue industry such as treat as applying filler in light industry, daily use chemicals, rubber and plastic, coating, and waste or used plastics, rubber also need be recycled.All these needs just can reach satisfied effect with after plastics, the rubber type of material ultra-fine grinding.But since plastic materials itself intrinsic, characteristics such as toughness big big as viscosity, general process is difficult to it is carried out the ultra-fine grinding processing.Domestic have a report, and Institutes Of Technology Of Nanjing adopts high-speed grinding wheel machine that rubber is carried out ultra-fine processing, and fineness reaches 300 μ m～700 μ m, has report to adopt high percussion device to freeze under the condition at deep cooling abroad and molding powder is broken to 200 μ m～700 μ m.Above-mentioned two kinds of methods are dry method, low-temperature grinding, and product granularity is thick, and latter's cost is very high, pulverize one kilogram of plastics and need the 1kg liquid nitrogen approximately, thereby can not satisfy industrial production requirement.
The object of the present invention is to provide and a kind ofly just can realize ultra-fine grinding at normal temperatures, and technology is simple, preparation cost is low, is suitable for plastics, the rubber normal temperature ultrafine grinding process of suitability for industrialized production.
The technical solution that realizes purpose of the present invention is: a kind of plastics, rubber normal temperature ultrafine grinding process, it is characterized in that its technological process is, to add water in the material of diameter＜10mm, and enter the high speed shear grinder, pulverizing circulates, material-water ratio 1: 0.1-20, grind pass 1-20, and filter while pulverizing, dry then, again dried material is entered high speed disintegrator and further pulverize and disperse, finally obtain the particle of average grain diameter＜110 μ m.
Principle of the present invention is: 1, be medium with water, so that can in time eliminate the heat that plastics or rubber produce in crushing process, avoiding high temperature to make plastic molting, is that fluid drives plastics or the rubber powder flows in the mill body simultaneously with water, avoids plastics or rubber to accumulate in and pulverizes in the thorax body; 2, the taper high-speed shearing machine that constitutes with microknife produces extremely strong shearing force and grinds the field of force and toughened plastic or rubber particles is sheared be milled to below the 200 μ m; 3, it is in small, broken bits to D50＜110 μ m with above-mentioned powder in water to grind machine with plane or the hard high abrasion of the meticulous height of the conical surface, and filters while pulverizing, dewaters.
The present invention compared with prior art, its remarkable advantage is: 1, realize ultra-fine grinding at normal temperatures, preparation technology simplifies greatly, and cost reduces significantly; 2, finished product fine size, part to tens/one who has only existing low-temperature grinding, (international most advanced level is the molding powder that the 1kg liquid nitrogen just can be produced 1kg200～700 μ m at present, but also do not comprise the energy consumption of process): 3, can dewater while pulverizing, produce continuously, isolated water is in time taken away the heat that produces in the crushing process, thereby has avoided the crushing process intensification; 4, because technology is simple, equipment requires low.So be suitable for large-scale industrial production.
Accompanying drawing is a kind of schematic flow sheet of plastics of the present invention, rubber normal temperature ultrafine grinding process.
Below in conjunction with accompanying drawing embodiments of the invention are described.
