Abstract
The invention discloses an activated rubber powder and making method, which compriss the following steps: allocating the component of waste tyre and alkynediols tetramethyl with molar rate at 100:3-10; doping activator (alkynediols tetramethyl) into waste tyre under normal temperature; stirring; wetting.
Description
Technical field
The present invention relates to a kind of rubber powder, particularly the rubber powder behind overactivation.
Background technology
By the rubber powder of damaged tire processing, main component is that rubber and various tire are made auxiliary agent, and is poor with other material compatibility, so influence its range of application, must just can make it recapture rubber character through activation treatment, recovers adhesion properties to a certain extent; Rubber powder after the activation can be used for fields such as asphalt modification, composite rubber-plastic material.
In order to improve the adhesive performance of waste rubber grain, the way one of present industrial employing is that employing tertiary butyl phenol formaldehyde resin is that vulcanizing agent, tin protochloride are the vulcanization system of promotor, improves its vulcanization rate and viscosity with halogenated method; The 2nd, at high temperature use the method for activator 420 (polyalkylbenzene phenol disulphide) and increase tin protochloride consumption to solve rubber viscosity and vulcanization rate, common 420 activators can rise to mould separates the promotion crosslinked action, make waste Crumb rubber desulfurization reduction rubber sticking property, then guarantee and the mixing of other material, reach modification purpose other material.That is to say that the adhesive performance method of conventional raising waste rubber grain all is to adopt the way of desulfurization to achieve the goal, but the sweetening process complexity, and environmental pollution is heavier, also will expend the energy simultaneously, and is very uneconomical.
The adhesive performance that how to improve waste rubber grain under the situation that does not need desulfurization becomes the current technical barrier that needs to be resolved hurrily.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art and a kind of activating rubber powder and preparation method thereof is provided, this activating rubber powder need not carry out desulfurization can obtain adhesive performance preferably.
The object of the present invention is achieved like this:
A kind of activating rubber powder, be that the component by following weight ratio is configured: scrap tire powder: tetramethyl alkynediols=100: 3-10, scheme is a scrap tire powder preferably: tetramethyl alkynediols=100: 5.
The preparation method of this activating rubber powder is very simple, is at normal temperatures the activator tetramethyl alkynediols to be mixed in the scrap tire powder in proportion, mixes and stirs wetting getting final product.
Wherein, the activator tetramethyl alkynediols is a kind of multi-functional nonionogenic tenside, and chemical composition is 2,4,7,9-tetramethyl--5-certain herbaceous plants with big flowers alkynes-4,7-glycol, molecular formula C
14H
24O
2, be white or little yellow wax, it is strong to have a pigment-dispersing ability, the their defoaming function of excellent low bubble and appropriateness.
Waste Crumb rubber is with of the prior art identical, and particle size range is at the 30-80 order.
Activating rubber powder by the method for the invention preparation has dispersiveness, levelling property, perviousness, rust inhibition and tackiness preferably, if it is used in pigment and bituminous modification, has mixing preferably.
The present invention has following advantage than prior art:
Activating rubber powder provided by the invention need can not give rubber powder higher adhesive performance through desulfurization process, recover its rubber character, production technique is very simple, has simplified operation, saved investment, simple to operate, nontoxicity, nuisanceless, the easy storage transportation of no burn into.
Embodiment
Below by embodiment the present invention is described in further detail, but the present invention has more than and is limited to these examples:
Embodiment 1: a kind of activating rubber powder is that the component by following weight ratio is configured: scrap tire powder: tetramethyl alkynediols=100: 3, at normal temperatures the activator tetramethyl alkynediols is mixed in the scrap tire powder in this ratio, and mix and stir wetting getting final product.
Embodiment 2: a kind of activating rubber powder is that the component by following weight ratio is configured: scrap tire powder: tetramethyl alkynediols=100: 5, at normal temperatures the activator tetramethyl alkynediols is mixed in the scrap tire powder in this ratio, and mix and stir wetting getting final product.
Embodiment 3: a kind of activating rubber powder is that the component by following weight ratio is configured: scrap tire powder: tetramethyl alkynediols=100: 10, at normal temperatures the activator tetramethyl alkynediols is mixed in the scrap tire powder in this ratio, and mix and stir wetting getting final product.
Activating rubber powder provided by the present invention can use aspect the modification of pitch and pigment.
Claims (3)
1, a kind of activating rubber powder is characterized in that it being that component by following weight ratio is configured: scrap tire powder: tetramethyl alkynediols=100: 3-10.
