Abstract
The invention provides a preparation method for modified mica powder used for rubber product filler, and belongs to the field of preparation for mica powder. In order to overcome the technical problem that the mica powder has high surface energy in the prior art, thus agglomeration is quite easy to generate when fill with the rubber raw material, and reinforcement effect is difficult to perform, the invention provides the preparation method for modified mica powder. The preparation method comprises implementing surface modification processing for the mica powder by using titanate, and controlling the modified time and temperature. The prepared modified mica powder can be used as semi-reinforcing filler and bulking filler to increase the volume and mass of the rubber, and reduce the production cost. Moreover, the hardness of the rubber is raised, and the oil resistant performance and technological performance are improved. The modified mica powder can be used for rubber product filler widely.
Description
Technical field
The invention belongs to the preparation field of mica powder, be specifically related to a kind of preparation method of the modified micaceous powder for rubber item filler.
Background technology
Rubber item mainly refers to and adopts natural and synthetic rubber to be the product of main Yuan Cai section process for processing, wherein also
Comprise by the rubber product of waste rubber regenerative ratio.Because the kind of rubber item is comparatively numerous and diverse.Cause be difficult to carry out detailed
Sort out.Under normal circumstances, rubber item can be roughly divided into natural rubber products and the large class of synthetic rubber articles two.
Natural rubber products.The main raw material that this kind of rubber item adopts is natural rubber, mainly originates in during para rubber drags for.After rubber tree epidermis is cut open, have milky liquid and flow out, it is called latex by us usually.Latex, after processing treatment, just can obtain natural rubber.So-called synthetic rubber just refers to and adopts different raw material monomers.By the rubber that the method entering work synthesis is obtained.Synthetic rubber more typically has sodium butadiene rubber, and this is by the famous chemist's NIKOLAY LEBEDEV of Russia using sodium Metal 99.5 as initiator and polymerizing butadiene.Along with this elastomeric appearance, the slow chamber of synthesis gets more and more, as styrene-butadiene rubber(SBR), chloroprene rubber etc.The latex that only can overflow from three leaf trees due to natural rubber obtains, and elastomeric footpath of meeting is more.So platform becomes the output of rubber considerably beyond natural rubber.
The activity that it is the various rubber item of raw material production that rubber item (rubberproduct) refers to natural and synthetic rubber, also comprises the rubber item utilizing waste rubber regenerative ratio.The utilization of rubber item in petroleum drilling and mining is a lot, common are rubber pkr, rubber-bag and cementing plug.
Mica is a kind of important inorganic nonmetal mineral fillers, fills it into the physical and mechanical properties that can improve rubber item in rubber raw materials, reduces the production cost of rubber raw materials simultaneously.But because mica powder surface energy is higher, direct filling very easily agglomeration occurs, be difficult to play its strengthening action.
Summary of the invention
For solving the problem, the invention provides a kind of preparation method of modified micaceous powder, adopting following technical scheme:
A preparation method for modified micaceous powder, is characterized in that comprising the following steps:
A, mica powder is broken to 1000 orders;
B, mica powder and the properties-correcting agent pulverized are pressed (50 ~ 60): the mass ratio of 1 mixes, and obtains mixture A;
C, mixture A is carried out stirring heating, after heat modification, obtain described modified micaceous powder.
Preferably, the properties-correcting agent described in step b is titanic acid ester.
Preferably, the stirring heating described in step c comprises following content: Heating temperature is 80 ~ 95 DEG C; Heat-up time is 15 ~ 20min.
Beneficial effect of the present invention is as follows:
The invention provides the preparation method of modified micaceous powder, adopt titanic acid ester to carry out surface modification treatment to mica powder, and time of modification and temperature are controlled, make mica powder effectively be distributed in organic polymer, improve itself and organic consistency, give full play to its strengthening action.Modified micaceous powder prepared by method provided by the invention, can be used as half reinforced filling and extending fillers, to increase rubber bodies sum quality, reaches the object reducing production cost, can also improve rubber hardness simultaneously, improve its oil resistance and processing performance.Mixed refining process performance can be improved and extend the sizing material shelf-time, making its not easily structurizing.
