Description
Technical field
The present invention relates to be ground, polishing tool technical field, and in particular to a kind of artificial quartz stone plate polishing abrasive material
And preparation method thereof.
Technical background
In the Home Industry that China develops rapidly, artificial quartz in lump as a kind of novel high polymer composite, except conduct
It is increasingly extensive in whole sector application outside the auxiliary products of cabinet industry.The sheet material of quartz is widely used in cabinet table surface, defends
Table top, Dining table top, hospital's table top and laboratory table top etc. between life.Current quartz, the especially conduct of artificial quartz in lump product
A kind of high-end table top, ground decoration facestock increasingly liked by vast construction material consumer deeply, in recent years the market share
Increased with 20%, domestic quartz annual turnover is more than 10,000,000 square metres within 2014.
Quartz is by the colorant of more than 90% natural quartz and 10% or so, adhesive and other regulation bonding, solidifications
Deng additive composition.It is by negative-pressure vacuum, dither shaping, heating cure maintenance, the production method of compression molding
The hair plates of formation, hair plates need to carry out fixed thick polishing, polishing could by it decorative cover perfect expressions out, but due to
Its hardness is especially high（Quartz material Mohs' hardness 7）, compact structure（2.35-2.5 grams/cc of density）, make it in hair plates
Requirement in fixed thickness bruting process to abrasive material is higher, and most durable stone material abrasive material on the market is for natural flowers hilllock of polishing at present
Rock beam material, but such abrasive material is used for polishing quartz, because quartzite slate is more difficult to mill, causes that grinding efficiency is low, abrasive material is damaged
Consumption speed is high, or even the problems such as the complete rear glossiness of sanding and polishing can be caused not high.
The content of the invention
It is an object of the invention to overcome existing building stones polished material to exist be not suitable for polishing artificial quartz stone plate and
Caused grinding efficiency is low, quick abrasion, close after polishing pool degree it is not high the problems such as, there is provided a kind of grinding efficiency is high, abrasion is slow, polish
The preferable artificial quartz stone plate polishing abrasive material of glossiness afterwards.
Another object of the present invention is the preparation method for providing above-mentioned artificial quartz stone plate polishing abrasive material.

Enter material agitator to be stirred, stir speed (S.S.) is 100 ~ 500rpm, after 5 ~ 30min of stirring, pours into step（1）Products therefrom,
It is again stirring for, stir speed (S.S.) is 100 ~ 800rpm, mixing time is 5 ~ 20min；
（3）By step（2）Gained compound add double-roll type material-twisting machine in, two roller spacing of adjustment be 5 ~ 10mm, left roller 50 ~
100rpm, right 100 ~ 200rpm of roller, compound is carried out to rub scattered dispersion；
（4）By step（3）Resulting material is poured into abrasive material mould, under vacuum after 3 ~ 10min of vibration compacting, 100 ~
200 DEG C of 1 ~ 5h of curing conservation, cooling and demolding obtains artificial quartz stone plate polishing abrasive material.
Compared with prior art, the present invention has the advantages that：
（1）The epoxy resin that the present invention is modified from Graphene as adhesive, using the sic powder of special ratios,
White fused alumina micro mist, high-carbon chromium iron, short carbon fiber etc. using graphited oil as auxiliary agent dispensing formulations, then add as filler
Enter auxiliary curing agent, the wearability of gained abrasive material is greatly improved, contrast the similar abrasive material of in the market, artificial quartz in lump of the present invention
