Description
Technical field
The present invention relates to rubber for tire sizing material production field, relate in particular to a kind of pad glue sizing material.
Background technology
Natural gum is widely used in tire industry and rubber industry because of it has excellent physical and mechanical properties.Because natural gum molecular weight high (molecular-weight average is about 700,000); Dry method with traditional is mixing; At first to plasticate to natural gum (reducing molecular weight) through mechanical force and high temperature degradation in the shear history of machinery, add required carbon black, WHITE CARBON BLACK and other acvators, anti-aging agent, vulcanizing agent then.The macromole of natural gum is badly damaged in this course, so that powerful wear hardness descends.For remedying powerful and abrasive decline.The a large amount of particle diameters that adopt of designer tradition are little, the in addition reinforcement of the big hard(carbon)black of specific surface area.Though powerful like this and abrasion can improve, sizing material is given birth to also raising thereupon of heat thereupon.So that tire causes early stage hat empty empty with shoulder running at high speed Yin Shengregao.In order to fall low-heat-generation, often add a spot of WHITE CARBON BLACK.WHITE CARBON BLACK has the advantages that the heat of giving birth to is low, wet-sliding resistant performance is good.
Conventional dry compounding process such as Chinese invention patent application (application number: 200910050337.2 applyings date: 2009-04-30) disclose the method that a kind of acceptor modified white carbon black strengthens truck tyre pad colloidality ability; This method is: Nano carbon white is removed moisture through 120 ℃ of vacuum-dryings; Carry out the coupling agent surface treatment, the consumption of coupling agent is a Nano carbon white powder weight 1%～10%; Keep the original production formula of rubber constant with the Production Flow Chart basis of invariable on; In rubber mixing process, add 20%～30% Nano carbon white composite granule after coupling agent modified of rubber weight; Test result shows that the tensile strength of truck tyre pad glue, tear strength, hardness etc. increase substantially behind the interpolation composite Nano WHITE CARBON BLACK powder.And the WHITE CARBON BLACK of using the mixing adding volume of conventional dry certainly will influence the brute force and the wear resisting property of sizing material.
But two deadly defects are arranged with the conventional dry compounding process: the one, WHITE CARBON BLACK is that hydrophilic inorganics is difficult to be added in the hydrophobic natural gum; Must carry out too mixing (increasing mixing hop count); Must destroy the globality of rubber molecular chain like this, cause powerful reduction.WHITE CARBON BLACK is used the mixing integraty that can't form natural gum and WHITE CARBON BLACK of dry method in addition.The sizing material of the WHITE CARBON BLACK of so a large amount of fillings obtains less than high-wearing feature.In a word, the hard(carbon)black that adds a large amount of high-specific surface areas can obtain the rubber unvulcanizate than high-tenacity, but it is hot excessive to cause sizing material to give birth to undoubtedly, and rolling resistance is high.And use the preparation method of liquid phase paddling process blended WHITE CARBON BLACK natural gum can remedy above-mentioned two deficiencies fully.
Liquid phase paddling process blending means such as Chinese invention patent application (application number: 201110064299.3 applyings date: 2011-03-17) disclose the preparation method of the mixing natural rubber material of a kind of wet method; Its method comprises: preparation slurry 15%～40% WHITE CARBON BLACK siccative is immersed in 60%～85% the deionized water; Adding coupling agent, tensio-active agent mixes to grind and produces latex mixed solution-the get natural rubber latex-WHITE CARBON BLACK water dispersion is joined in the latex; Mix into latex mixed solution-flocculation-in mixed solution, add acetic acid; Wash glue and dehydration-deliver to the granulation of rubber granulation machine through rubber washing machine, the sizing material grain is sent into carried out drying in the box-type drying cabinet then.The tire drag that adopts this method to make is little, and living heat is low, and tensile strength and tearing strength are high, and the ageing-resistant performance of sizing material is good.Realized that the mixing of WHITE CARBON BLACK carry out in liquid phase, dispersed and homogeneity raising.But the WHITE CARBON BLACK slurry need adopt deionized water to soak in this patent, and simultaneously, in the course of processing, needing has increased process step like this through grinding, and has improved production cost; In addition, in whipping process, can occur condensing, macrobead occur, cause mixing inhomogeneous for natural rubber latex.
The applicant has applied for that Chinese invention patent (applying for patent of invention on the same day) discloses the preparation method that a kind of liquid phase mixes WHITE CARBON BLACK and natural gum, and this method comprises the steps:
1) pulp preparation
