Abstract
The invention relates to a rubber color master-batch and the preparation method thereof, belongs to the rubber master-batch technology field. The rubber master-batch is prepared by the following materials by weight parts of: pigment 50-65, naphthenic oil 10-25, calcium dodecanoate 3-5 parts, stearic acid derivative 0.5-1 part, nanometer material 0.5-2 parts, low molecular polymer 0-8 parts and rubber compound 15-22 parts. Compared with the prior arts, The invention adopts compound surface treatment method, covers the pigment particles to the maximal degree, reduces the surface energy to keep it in stable state; adopts naphthenic oil as moistening agent, avoids pigment deliquescence, and guarantees the brilliant color of product; and adopts nanometer material which can re-arrange quickly with the rubber compound structure and diffuse after rubber product is treated by high temperature sulfuration, increases the absorption and reflection to light, and improves the light resistance of product.
Description
[technical field]
The present invention relates to the rubber color master-batch technical field, exactly is a kind of rubber color master-batch and preparation method thereof.
[background technology]
Rubber color master-batch, as the term suggests be the painted color base of rubber item, the rubber color master-batch main component is: pigment, tensio-active agent and carrier; Has only the pigment that will pass through the science selection; Tensio-active agent and carrier are handled through special process again, and then with suitable ratio combination; Can succeed in developing lovely luster, the rubber color master-batch of excellent property.It mainly is applicable to rubber item and rubber plastic blend color articles.
Rubber item requires different to the glue kind because of its purposes is different, rubber is divided into two big types: natural and viton, natural gum are generally selected smoke sheet rubber 3#, 4# for use; And synthetical glue commonly used is: butylbenzene, neoprene, chlorinated rubber etc.; Through concluding rubber item be: hand cart tyre, all rubber shoes, half rubber overshoes, ball, anti-articles for use of labor, mining electric wire, submarine optical fiber cable sheath and rubber plastic blend communication electric wire etc.
At present, existing both at home and abroad multinomial company or individual's patented invention production is used for the look mother of rubber coloring, but has following three aspect problems:
One, storage stability is poor, mainly show to surface of pigments handle science not or the hydrophobic performance of the tensio-active agent selected for use poor, new cohesion takes place and causes in pigment in storing half a year or 1 year process, serves as serious with black, blue look mother especially.
Two, the goods color is not bright-coloured, and color is the performance of pigment color development, and pigment not only can deliquescence after receiving moisture and corroding; The dispersing property that more serious is in the rubber medium is poor; Thereby cause pigment color development in goods insufficient, cause its major cause for having selected whiteruss for use, promptly white oil is the wetting agent of pigment; And the sulfonic acid group on the white oil carbochain very easily absorbs airborne moisture.
Three, the relative light fastness of goods is poor, and rubber item must pass through high temperature vulcanized, makes it reticulate structure by linear structure, thereby improves the brute force and the elongation of goods, and through after high temperature vulcanized, the goods internal structure is arranged again, until relatively stable.
[summary of the invention]
The objective of the invention is to overcome the deficiency of prior art, adopt unique composition of raw materials,, prepare a kind of rubber color master-batch of stable performance in conjunction with compound surface treatment method.
For realizing above-mentioned purpose, design a kind of rubber color master-batch, it is characterized in that adopting the feedstock production of following ratio of weight and number to form:
Pigment 50-65
Naphthene base crude oil 10-25
Stearic acid calcium salt 3-5
Stearic acid verivate 0.5-1
Nano material 0.5-2
Low-molecular(weight)polymer 0-8
Sizing material 15-22
Described pigment is mineral dye or pigment dyestuff.
Described mineral dye is any or an arbitrary combination of carbon black, white titanium pigment, iron oxide yellow, iron oxide red; Described pigment dyestuff is any or an arbitrary combination of the blue or green pigment of azo pigment, azo condensation pigment, phthalein, heterocycle pigment.
Described stearic acid calcium salt is a calcium stearate.
Described stearic acid verivate is the octadecyl tetrahydroglyoxaline.
Described nano material adopts at least a of zinc oxide or silicon oxide.
Described low-molecular(weight)polymer is the Vilaterm of molecular weight 1500.
Described sizing material is any in tree elastomer, styrene-butadiene rubber(SBR) or the terpolymer EP rubber.
A kind of method of manufacture of rubber color master-batch is characterized in that the raw material of above-mentioned ratio of weight and number is adopted the following steps preparation: the Combined Processing of (1) pigment: naphthene base crude oil, stearic acid calcium salt, low-molecular(weight)polymer are mixed temperature 85-90 ℃ in kneader; 1 hour time; Under agitation condition, be cooled to 50-55 ℃, adding pigment is mediated wetting, 1.0-1.5 hour; Add the stearic acid verivate again, mix carries out three rollers and grinds after 0.5 hour; (2) blend: after grinding finishes, mixed 1.5 hours, add nano material again, remix 0.5 hour with sizing material; (3) section obtains finished product.
The present invention compared with prior art adopts compound surface treatment method, and greatly degree granules of pigments is coated reduced its surface energy, makes it be in steady state all the time; Adopt naphthene base crude oil as wetting agent, avoided the deliquescence of pigment, guaranteed the bright-coloured of goods colors; Adopt nano material, make rubber item after high temperature vulcanized, nano material can be arranged again with the sizing material structure rapidly and spread, and has increased absorption and reflection to light, improves the light fastness of goods.
