Description
Technical field
The present invention relates to a kind of talcum powder, relate in particular to a kind of preparation method of carrier-free talcum powder master batch.
Background technology
Talcum is a kind of aqueous silicate minerals with laminate structure, and commonly used is the aggregate of sheet, flakey or compact mass, and its structure unit's interlayer maintains mutually with molecular linkage, and the interlayer section exists ionic linkage, covalent linkage.Two structural unit interlayers are interlamination region, and not moisture and positively charged ion only depends on faint van derwaals to connect, so the very easy LED reverse mounting type that is dissociated between unit layer.When talcous this sheet structure made the talcum powder filled plastics, some performance of material can obtain bigger improvement.At first, talcum powder can improve creep resisting performance under the rigidity of packing material and the high temperature.When the talcum powder particle when adding that man-hour, the Flow of Goods and Materials direction was arranged, by the principle of least resistance, it is arranged basically all in the form of sheets, is linked to be sheet by small pieces.Thereby the raising of material stiffness is significant on specific direction.Secondly, talcum powder can significantly improve the packing material thermotolerance.Flaky talcum powder can make the heat-drawn wire of material improve on specific direction.Talcum powder is filled in the materials such as polypropylene and can gives scantling good stability, non-warpage, heat-drawn wire height, modulus and the big characteristics of hardness.Simultaneously, in mineral filler, talcous hardness is low, and is little to equipment wearing.Yet, when use is talcous, can bring powder to fly upward environment is formed secondary pollution problem, if talcum powder is entrained in makes master batch in the resin and can bring between the different resins matrix problems such as consistency difference again, these situations have all influenced talcous use in addition.In order to give full play to the advantage that talcum powder can effectively improve material mechanical performance, reduce in its use because the harm of the secondary pollution that dust from flying caused, need on the basis of talcum powder surface modification, develop the harm that new production technology is eliminated its powder environmental pollution.
Add the interface expanding material: it is generally acknowledged that the interface expanding material is maleic anhydride (MAH) polymers grafted preferably, use screw extrusion press to make usually.But, since the extrusion temperature height, the chain rupture that easily produces polymer molecule, simultaneously, and residence time weak point in forcing machine, MAH graft reaction efficient is low, has the etching problem of MAH to extrusion equipment in addition, so the suitability for industrialized production of this kind method is restricted.
The in-situ polymerization surface modification: before talcum powder adds resin to, use acrylic monomer at its surface aggregate, the product after the polymerization again and resin alloy.This method can effectively be improved resin and the cohesive action of talcous interface, help talcum powder in the PP matrix dispersion and peel off.But, the complete processing relative complex.
Aspect granulation, current use extrude tie rod water-cooled, earnestly water-cooled or technology such as fervent air-cooled extruding pelletization and vacuum compression granulation, these agglomeration techniques need be handled raw material under the condition of vacuum compression or heating, the production technique relative complex.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of preparation method of carrier-free talcum powder master batch, purpose is to reduce talcous dust pollution, production technique is oversimplified, consistency between the resin matrix of raising master batch and application.
For reaching above-mentioned purpose, the preparation method of a kind of carrier-free talcum powder master batch of the present invention is made of following step: the preparation additive: thinner and adhesion agent are mixed in proportion, and wherein thinner is 90%-99%, and adhesion agent is 1%-10%; Handle talcum powder: blended additive and talcum powder are mixed, and wherein additive is 15%-35%, and talcum powder is 65%-85%; The talcum powder moulding: the talcum powder that combination treatment is crossed is put into forcing machine normal temperature and is extruded, the granulation extrusion pressure is the 1-2 MPa, extrude the particulate diameter and be controlled at 1-5mm, length-to-diameter ratio is controlled at 1-4, and the particle of extruding is dried down at 120-180 ℃ and obtained product in 0.5-1.5 hour; Above-mentioned percentage ratio is weight percentage.
Described preparation additive: thinner, adhesion agent and surface-modifying agent are mixed in proportion, and thinner is 90%-98%, and adhesion agent is 1%-8%, and surface-modifying agent is 1%-8%, and above-mentioned percentage ratio is weight percentage.
Described thinner is one or both mixtures of water or water and pure and mild ketone.
Described alcohol is ethanol, propyl alcohol or butanols; Ketone is acetone, butanone or pimelinketone.
The middle water of one or both mixtures of described water and pure and mild ketone is 85%-95%, and alcohol, ketone or alcohol and ketone are 5%-15%.
Described adhesion agent is phosphoric acid salt, vitriol, borate, silicate, polyacrylic ester, polyvinyl alcohol, urethane or polyvinyl acetate (PVA).
Described phosphoric acid salt is sodium phosphate or potassiumphosphate; Vitriol is sodium sulfate or vitriolate of tartar; Borate is Sodium Tetraborate or potassium borate; Silicate is water glass or potassium silicate; Polyacrylic ester is polymethyl acrylate, polyethyl acrylate or butyl polyacrylate.
Described surface-modifying agent comprises silicane, titanate ester, aluminium esters of gallic acid, aluminium titanium complex class, borate ester, rare earth class or stearate.
Described silicane is KH550, KH560, KH570; Titanate ester is a sec.-propyl tricarboxylic metatitanic acid fat, hydramine titan-alkoxide acid esters, dioleoyl Diisooctyl phosphoric acid acyloxy volt isopropyl propionate; The aluminium esters of gallic acid is KR-TTS; Aluminium titanium complex class G-1, G-2; Borate ester SBW-1, SB-618T; Rare earth class is FR-3, HY-041; Stearate is a sodium stearate, potassium stearate.
Advantageous effect of the present invention: solved in the use of conventional talc powder because powder flies upward the problem of environmental pollution that brings.Traditional have problems such as being prone to the consistency difference between carrier master batch and blending resin matrix, and the product that present technique is produced can be directly and resin alloy, and not resinous carrier, effectively avoided the problems referred to above.Talcous content can reach more than 98% in the product.Extrude the particulate diameter and be controlled at 1-5mm, length-to-diameter ratio is controlled at 1-4, can keep shape in process such as packing, transport, deposit behind the particle drying in this range scale, can not be broken into powder.Product is difficult for pulverizing in transportation, can be dispersed to 300-8000 order before the granulation rapidly by high-speed stirring during use, the matrix material that blend such as this carrier-free talcum powder master batch and rubber, plastics form can be used for each field such as automobile, electronics, petrochemical industry, machinery.
