Description
Technical field
The present invention relates to a kind of plastic matrix and preparation method thereof with antibacterial, mildew-resistant, function for expelling pests.This plastic matrix has suitable antibacterial, the mildew-resistant of the antibacterial masterbatch with silver ions, function for expelling pests, but cost significantly reduces.
Background technology
The antibacterial masterbatch of current known plastics, the silver ions raw material of employing is antibacterial, but the anti-mold effect no doubt fine expensive price advantage not possessing universal use.Thus widely using of antimicrobial plastic master batch is constrained.
Sulphur has certain bacteriostasis property, is usually used in stifling or burning for antibacterial and expelling parasite, is also more common in and adds in pharmaceutical products or cosmetics of everyday use for sterilization and antibacterial.Also plastics may be used in theory.And the cost of sulphur significantly lowers compared with the antibacterial system cost of silver ions raw material.So prior art comprises contriver carry out excessive quantifier elimination and trial interior, but this area never has the technology of successful Application to report.
Summary of the invention
Main purpose of the present invention is to provide a kind of sulphur antimicrobial plastic master batch and preparation method thereof.
Concrete technical scheme of the present invention is: a kind of sulphur antimicrobial plastic master batch, it is characterized in that: comprise the trickle powder of sulphur, inorganic powder, both ratios are 1: 2.8 ~ 3.1, modified active agent, and the ratio of consumption and sulphur micro mist and inorganic powder total amount is 0.8 ~ 1.2: 100; And endosperm dispersion agent, the carrier of the shaping necessity of masterbatch.
The present invention adopts functional raw material sulphur, its resource relative abundance, cheap; And solve those skilled in the art thirst for for a long time solve and unsolved technical problem, successfully develop sulphur plastic matrix, plastic matrix and the plastics produced not only have excellent antibacterial, antimildew function, also there is obvious anthelminthic effect, common insect, as fly, mosquito, cockroach etc. are all natural in this product.General microorganism such as acarid cannot be survived on its surface.Consumption as dispersion agent, carrier is then needs according to plastics finished product and shaping the needing choose reasonable kind and consumption to bacteriostasis property and have no significant effect of masterbatch.
And in order to further optimization and the raising of product performance, the parameters optimization and the starting material that present invention also offers product are selected:
The median size of described sulphur micro mist is 0.5 ~ 2 μm; The median size of inorganic powder is suitable with the median size of sulphur micro mist.This is preferred particle size range, and particle diameter excessive then product bacteriostasis property reduces; The reduction of particle diameter too small not only bacteriostasis property but also processing fluidity etc. are poor, and also easily decomposition easily causes dust.Particle diameter quite namely median size is basically identical, as particle diameter detection and determine, be that those skilled in the art can be realized by multiple method, such as, use laser particle detector detection etc.
Described inorganic powder is at least one in sulphur calcium, calcium carbonate, talcum powder, titanium dioxide.This is through the preferred inorganic powder of verification experimental verification, especially utilizes the product performance of sulphur calcium, calcium carbonate more outstanding.Inorganic powder is be convenient to processing to the dilution of sulphur micro mist on the one hand, is also the necessity ensureing product performance simultaneously, and this is also the core technology point failing in conventional art to find and solve.
Described carrier is at least one in Zinic stearas, barium stearate, lubricant, polyethylene wax.Dispersion agent and carrier mainly improve mixing and granulation processing characteristics further, and realize granulation.Carrier is selected mainly to choose according to low-temperature plasticizing principle.
Described modified active agent is at least one in stearic acid, Aluminate, titanic acid ester, silane coupling agent.
Further preferably common prescription is: described masterbatch comprises the trickle powder 20% of sulphur, inorganic powder 60%, modified active agent, endosperm dispersion agent 8%, carrier 12 %, and the ratio of modified active agent and sulphur micro mist and inorganic powder gross weight is 1: 100.This of the present inventionly most preferably to fill a prescription.
The manufacture method of aforesaid sulphur antimicrobial plastic master batch, is characterized in that: step comprises:
A, by sulphur micro mist and inorganic powder mixed diluting, mixing rotating speed 180 ~ 230 revs/min;
B, to add after modified active agent high-speed mixing under 300 ~ 600 revs/min of rotating speeds;
C, parallel double-screw Banbury mixer mixing granulation is utilized to obtain antibacterial masterbatch through the material of a, b two-step pretreatment and endosperm dispersion agent, carrier;
In whole treating processes, processing temperature controls at 85 DEG C-95 DEG C.
The technique that the machining of masterbatch of the present invention adopts, equipment are also all that conventional mature equipment tooling cost is low, technology controlling and process is simple, as long as the processing temperature of controlling well, the starting material of Choice and process temperature and Controlling Technology temperature adaptation, mainly namely select the carrier being applicable to low-temperature plasticizing to process easily.Easy to process, tooling cost is low.
Mixing machine is generally universal mixing machine, and parallel double-screw Banbury mixer is also existing mature equipment.
Further, in the described course of processing, the gas of volatilization is passed into gas sweetening tank purifying treatment.Namely consider sulphur possibility work in-process thermolysis and volatilization, so preferably process the dust of the gas that equipment volatilizees and spilling.
Such as mixing machine adopts the silicone rubber O-ring of good sealing effect, and ensure that equipment upper cover and body do not leak material, upper cover breather hole installs flexible rubber interface additional, introduces tank settling tank by pipe connecting, eliminates sulfur dust, prevents sulfiding gas diffuse source.
The advantage of parallel double-screw Banbury mixer be can continuous seepage, steady quality, production efficiency is high, energy consumption is low, labor strength is low, good operational environment.Produce for adapting to masterbatch of the present invention, the system preparation gas sweetening tank of parallel double-screw Banbury mixer Vacuum Mixture technological process, eliminates sulfiding gas diffuse source.
The whole course of processing strict controlled working process temperature, is generally no more than 85 DEG C of-95 DEG C of scopes.This is also the important measures controlling sulphur volatilization Sum decomposition, ensure that quality product.
Plastics and the production method that this masterbatch of application is correspondingly provided of the present invention.
This product is added in plastics and namely obtain antibacterial plastic prod.
Product of the present invention and method are because of with low cost, simple, have the prospect widely using and promote, and will be the mainstream products of antibacterial, mildew-resistant, expelling parasite, promote the well-being of mankind.
