Description

The general plastic color mother of heavy body

The present invention relates to a kind of general plastic color mother of the painted heavy body of thermoplastics that is applicable to.

There is the shortcoming of narrow application range in the general look mother of existing plastics.As the universal chromogen ratio low (the look mother: moulding is 1: 75～100) that company limited of West Germany Canon (Hong Kong) produces, look female consumption is big.The universal chromogen that Leqing, Zhejiang county colour batch factory produces, complex production process, fusing point low (100 ℃), its carrier is a polyethylene wax, is non-polar compound.According to the rule of " polarity is close ", itself and non-polar polymer consistency are good, and not all Compatibility in Plastics is good.Some needs as nylon, with the universal chromogen of polyethylene wax as carrier, then can not be mixed together drying with plastics at comparatively high temps exsiccant plastics.

Task of the present invention is that providing a kind of to the public can overcome above-mentioned drawback, be applicable to thermoplastics, comprise the general plastic color mother's of heavy body that nylon, high-impact polystyrene, polyethylene, polypropylene, polyoxymethylene, polycarbonate, polymethylmethacrylate, polyvinyl chloride, polyethylene terephthalate, ABC, ASA, PUR, SAN etc. are painted prescription and production technique thereof.

The present invention realizes by following proposal.

Main points are to select for use with all Compatibility in Plastics well, and fusing point is higher, and N, the N-ethylene bis stearamide that can hold more face (dying) material are made carrier.

The principle close, and the derivation of Hildebrand etc. according to solubility parameters, when two kinds of material isothermals mixed, the mol enthalpy of mixing can be expressed from the next: $\mathrm{\Δ}{\mathrm{fl}}_m=\frac{n_1{v}_1{n}_2{v}_2}{n_1{v}_1+n_2{v}_2}{[{\left(\frac{{\mathrm{\ΔE}}_1}{v_1}\right)}^{\frac{1}{2}}-{\left(\frac{{\mathrm{\ΔE}}_2}{v_2}\right)}^{\frac{1}{2}})}^2$ $=\frac{n_1{v}_1{n}_2{v}_2}{n_1{v}_1+n_2{v}_2}[{\mathrm{\δ}}_1-{\mathrm{\δ}}_2{]}^2$

δ ₁, δ ₂Solubility constant for component 1,2; n ₁, n ₂Mole number for component 1,2; V ₁, V ₂Molecular volume for component 1,2; Δ E ₁, Δ E ₂Internal cohesive energy for component 1,2.

Mol enthalpy of mixing Δ Hm is the interaction energy between the same constitutional unit, and is different with interaction energy between two kinds of constitutional units or between constitutional unit and solvent molecule and produce.For the non-polar molecule system, mixing process does not have heat effect or heat absorption.The absolute value of the solubility parameter difference of two kinds of compounds is littler, and the numerical value of Δ Hm is littler, and is then easy more compatible.Work as δ ₁And δ ₂When equating, enthalpy of mixing Δ Hm is zero, no heat effect.Work as δ ₁And δ ₂Difference is big more, and dissolving and heat absorbing is just many more, is unfavorable for dissolving more.Table (one) is listed the solubility constant δ of common polymkeric substance.

According to the rule of " polarity is close ", the solute that polarity is big is dissolved in the big solvent of polarity again, and the solute that polarity is little is dissolved in the little solvent of polarity.In the thermoplast plastics, some polymkeric substance is a polar, and some polymkeric substance then is nonpolar.

The δ value of table (one) common polymkeric substance

According to above-mentioned principle, the solubility parameter value of summarizing most of plastics is many 8～11 Between.Therefore reach a conclusion: (1) chooses its solubility parameters value of carrier 9～10

Between be best, (2) carrier and polarity and the non-polar polymer performance that mixes is good, (3) carrier fusing point is higher, and can hold more face (dying) and expect.

Multiple material property is compared, think that selecting the solubility parameters value is 9.2～9.6 N, N-Z the support bis-stearamides be best as carrier.130～145 ℃ of N, N-Z support bis-stearamides fusing points, its molecular structure contains polar group and non-polar group, these two kinds of groups show different consistencies in different polymkeric substance, in plastics, have different consistencies thereby demonstrate it, determined it and thermoplastics to have good consistency.N, N-Z support bis-stearamides, can make 20～70% face (dying) material, are evenly distributed in its stable and open lattice, just assemble between phase and phase the homodisperse phase; N, N-Z support bis-stearamides plays an important role to aspects such as the diffusion of pigment, infiltration, homodisperse on the other hand.When the look mother disperses therebetween in plastics, lattice is destroyed, is dissolved in the plastics rapidly, thereby in the lower plastics of face (dying) material concentration, trickle face (dying) material particle is disperseed rapidly.

Another main points of the present invention are closely to go to contrast to the performance of face (dying) material and to the suitability of resin to select, and mineral dye, pigment dyestuff and the dyestuff that the general look mother of adaptation heavy body of the present invention assert in screening, as table (two).In order to guarantee the granularity of face (dying) material, to face (dying) material after assert, take the way of extra-fine grinding, make it reach diameter, and then face (dying) material is melt into mutually with carrier gives dispersion uniformly less than 40 microns powder.When coloured plastics, the uniform distribution of face (dying) material just is guaranteed like this.

After carrier, the choosing of face (dying) material, have complete performance, also need add corresponding additive, that is: brightening agent, lubricant, dispersion agent, tackifier, releasing agent in order to guarantee the general plastic color mother of heavy body.

The general plastic color mother of heavy body also can derive the general colour batch of the function that contains auxiliary agent, and the functional master batch of derivation has: the general look mother that foams, the general look mother of antioxygen, the right general look mother of resistance etc.
