Description

It is a kind of suitable for preparing the ball mill used amino film plastics pellet

Technical field

The utility model is related to a kind of ball mills, and in particular to a kind of suitable for preparing what is used amino film plastics pellet Ball mill.

Background technology

Moulding compound is also referred to as thermosetting plastics, and the material that can be moulded is referred in the utility model.Amino film plastics Referred to as aminoplast is with the amino resins solid material as main component in synthetic resin, according to the coherent condition of product Difference, amino film plastics are divided into powdery moulding compound and graininess moulding compound.Since graininess moulding compound will not be taken in truck Bridge（It is not known as putting up a bridge toward falling）, therefore it is more suitable for the thermosetting plastics injection molding machine of automation..Amino resins is according to being used The difference of raw material, is generally divided into urea-formaldehyde resin, melamine resin and aniline-formaldehyde resin etc., and amino film plastics Then using corresponding amino resins as main component, using cellulose, minerals as filler, addition lubricant, curing agent, pigment and its His additive and be made, and be known as urea moulding material, melamine moulding compound and croak amine moulding compound successively.

There are two types of the manufacturing methods of traditional amino film plastics.The first is using one-step technology, second of use Be two-step process.It is illustrated by taking urea moulding material as an example below.

The one-step technology includes slurrying, vacuum mixing, crushing and sub-sieve（Or tabletting）And etc..The slurrying step Suddenly it is to add in formaldehyde and the methenamine as catalyst under stirring in pulping tank, after mixing, adds urea and made Slurry keeps temperature of charge below 40 DEG C so that and with urea addition reaction occurs for formaldehyde, generates monomethylol urea, and in system Interior introducing methylol groups.The vacuum mixing step refers to by filtering put slurries into blender, then in blender Remaining methenamine is added in, then adds in pigment, lubricant and other auxiliary agents, starts agitating paddle high-speed rotation so that formaldehyde Further addition reaction occurs with urea and generates dimethylol urea and generation dehydrating polycondensation reaction（Also referred to as precondensation Reaction）And generate the initial stage Lauxite of linear structure.Add the cellulose as filler（Typically pulverized small paper Piece）, after treating that slurries are fully absorbed by cellulose, heater so that when material temperature reaches 40 DEG C, start to vacuumize, vacuum Degree is maintained at below -85kPa so that moisture content to 4% or so.Material slowly up to rising to 75~80 DEG C, react 20 minutes by heating Afterwards, discharging.In this step, due to polycondensation reaction so that molecular weight is continuously increased, the viscosity of material also constantly increases.Continuous High-speed stirred in, material repeatedly conglomeration again disperseed repeatedly, finally as the essentially identical uniform particle of size.Described Pulverising step is to crush particulate material.The sub-sieve step is by sieving, takes between 20~100 mesh after pulverising step Particulate material as amino film plastics finished product.The tableting step is that the material after pulverising step is pressed into several millimeters greatly Small sheet finished product.Seen from the above description, although the process CIMS of one-step method is short, and seal is preferable, so as to the feature of environmental protection Preferably.But there are still it is more the technical issues of, first, in its vacuum mixing step, due to final aqueous of material to be caused Rate drops to 4% or so, therefore 5 hours will be up to the vacuum dehydration time by reacting, and so that energy consumption is higher.If second is that in vacuum The color control of material is bad in whipping step, and the color of obtained moulding compound finished product can not then adjust, and severe patient can cause This batch of product is scrapped.Third, for moulding compound finished product, if other indexs such as demolding performace, hardening time and moisture content are not It is suitble to user's requirement, then can not also adjusts, severe patient will also result in scrapping for product.

The technique of the two step method acts on behalf of vacuum mixing step, and true compared with one-step method, by vacuum kneading step After empty kneading step, the drying steps of the special drying equipment of use are increased rather than as one-step method directly true Moisture is sloughed using the method vacuumized in empty mixing apparatus.And then powdery finished product is obtained after crushing, ball milling, sieve powder, Or obtain graininess finished product after being granulated to the powder after sieve powder.Kneading in two step method, is conducive to addition and precondensation Reaction, due to the drying steps specially set, therefore in vacuum kneading, for the extent of reaction of moisture content and precondensation, has no Harsh requirement.Therefore, the time of vacuum kneading step can be shorter, so that energy consumption declines.In ball milling step, due to Related auxiliary material can be added in charging, and so that yield rate is higher.Conventional preparing makes in amino film plastics pellet The discharging method of ball mill is that ball milling body carries out 360 degree rotation, one side blowing, this kind of structure and discharge method speed on one side It spends soon, is also easy to produce a large amount of dust, material waste or even the health to worker is caused to bring hidden danger.In addition, work as ball mill When interior material will go out, ball mill is still according to 360 degree of continuous operations, since materials inside is less, steel ball or porcelain ball（System Referred to as abrading-ball）It is wandered to one side and is also easy to produce loud noise, cause noise pollution.
