Abstract
The shaped compound granite material is made up of natural granite, unsaturated polyester resin No.191, anti-ageing agent, antioxidant, and toughening agent through combination, solidification and curing and features high antiwear nature similar to that of natural granite, good workability and low cost.
Description
The invention belongs to building and ornament materials, particularly a kind of composite granite shaped material and production method thereof.
At present, no matter building decoration and fitment is to use organic material still to adopt inorganic material with artificial compound flower hilllock rock goods, all has following defective: (1) decorative pattern has tangible artifacts, and easily changes, and fades; (2) some technical performance, particularly rub resistance, ageing resistace are far away not as good as natural granite; (3) can only produce the product that sheet material etc. has simple moulding, a kind of " tile made of artificial granite and marble for wall and floor; this wall floor tile mainly constitutes basic unit by alumina, cement, ammonium alum, sandstone etc.; constitute surface layer by unsaturated polyester resin, curing compound, accelerator, quartz sand; though this product has the production technology characteristic of simple; product itself exists still not that antifriction scrape along workability is poor; easily aging is disclosed in the Chinese patent 92101958.0, and only can make the wall floor tile, be difficult for bonding firm shortcoming.
The objective of the invention is at the prior art above shortcomings, provide a kind of manufacturing process simple, the product strength height, rub resistance, anti-aging, have good workability, and have the artificial compounded type granite shaped material and the production method thereof of low manufacturing cost.
One of purpose of the present invention is achieved in that a kind of composite granite shaped material, it is characterized in that this section bar is is major ingredient with various natural granite stones, unsaturated polyester resin 191, be equipped with the auxiliary agent that comprises cyclohexanone peroxide, naphthoic acid cobalt, 2-(2 '-hydroxyl-5 ' aminomethyl phenyl) BTA, the concrete proportioning of each component following (being as the criterion) with 100 parts of natural granite stone leftover bits and pieces:
Natural granite stone leftover bits and pieces 100
191 unsaturated polyester resins 15～30
Cyclohexanone peroxide 0.5～0.9
Naphthoic acid cobalt 0.2～0.6
2-(2 '-hydroxyl-5 ' aminomethyl phenyl) BTA 0.02～0.05
Wherein, unsaturated polyester resin 191 is the commercial goods, is the pasty materials in styrene such as maleic anhydride, ethylene glycol, make adhesive in product of the present invention, when the production technology temperature was high, required 191 amount was less, when the production technology temperature was low, required 191 amount was more.But 191 amount is too much, and overall viscosity is increased, and is difficult for machine-shaping, measures too smallly, can not well granite be bonded together.The optimum amount scope that experiment showed, unsaturated polyester resin 191 is 18～25; Cyclohexanone peroxide is mainly made curing compound in the present invention, naphthoic acid cobalt is done accelerator, both consumptions are big more, to solidify required time short more for product in the manufacturing process, when consumption surpasses 0.8,0.6 respectively, it is too short that product solidifies required time, and enough operating times can not be arranged, and experimental results show that the optimum amount scope of cyclohexanone peroxide and naphthoic acid cobalt is respectively 0.5～0.8 and 0.2～0.4; 2-(2 '-hydroxyl-5 ' aminomethyl phenyl) BTAs are made antioxidant in the present invention, purpose is the toughness for the antioxygenic property that improves product, ageing resistace and increase product, pentaerythritol ester is made aging-proof agent, dioctyl phthalate is made flexibilizer to select four [β-(3.5-di-t-butyl-4-hydroxy phenyl) propionic acid] for use, the amount that the three adds is too small, do not have due effect, excessive, there is no need, the amount ranges that experiment showed, the three is respectively 0.0 2～0.05,0.01～0.06,0.5～0.8.Also can make flexibilizer with dibutyl phthalate or BBP(Butyl Benzyl Phthalate; In order to increase anti-ultraviolet ability of product and photostability, can in product, add a certain amount of ultraviolet vapor and light stabilizer.
Two of purpose of the present invention is achieved in that a kind of production method of granite shaped material, it is characterized in that this production method comprises following activities:
1. batching: will required various raw materials good by the proportioning weighing, after earlier will other the various components except that granite putting into measurer and stirring, with the building stones adding, stir evenly again, standby;
2. moulding: the above-mentioned material for preparing is injected mould, under 20～50 ℃ temperature condition, make it tentatively finish synthetic reaction and moulding;
3. maintenance I: under the condition of 20～50 ℃ of temperature, humidity≤75%, allow the maintenance 8～12 hours in mould of the goods of above-mentioned one-step forming just, make its primary solidification;
4. maintenance II: after the said products demoulding, keep flat and place aeration-drying place,, under the condition of humidity≤75%, placed 8～10 days, make its thorough curing at normal temperature;
Above-mentioned resulting product again through the activities of corase grind, correct grinding, is promptly got product-composite granite shaped material of the present invention.
Production method activities of the present invention is in 2,3 steps, and is when temperature is lower than 15 ℃, synthetic and to solidify required time longer, it is slow that reaction is carried out, and productivity ratio reduced, when temperature is higher than 60 ℃, goods are difficult for solidifying, and production can not normally be carried out, and experimental results show that, optimum temperature range is 20～40 ℃, in this two step, when humidity＞75%, goods can not solidify substantially, production can not be carried out, thus humidity should be controlled at≤75% scope in.
The present invention compared with prior art has the following advantages: 1. because this product is a major ingredient with granite and unsaturated polyester resin 191, thus have higher mechanical strength, good scratch-resistant performance, and have and the akin decorative pattern of natural granite; 2. owing to do not contain cement, so have workability and formability preferably, not only can produce sheet material, and can produce architectural decorative and fitting materialses such as profile shapes, sanitaryware; 3. production technology is simple, and is cheap, has only 1/3 of natural granite.
Below in conjunction with specific embodiment in detail, the present invention is described in detail.
Be as the criterion with 100 parts of natural granite leftover bits and pieces, each component pressed following proportion speed weighing:
Natural granite stone leftover bits and pieces 100
191 unsaturated polyester resins 18～25
Cyclohexanone peroxide 0.5～0.6
Naphthoic acid cobalt 0.2～0.4
2-(2 '-hydroxyl-5 ' aminomethyl phenyl) BTA 0.02～0.05
Four [β-(3.5-di-t-butyl-4-hydroxy benzenes 0.01～0.04

Wherein two (3.5-di-t-butyl-4-hydroxybenzyl phosphonic acids list diester) nickel are light stabilizer;
Four [β-(3.5-di-t-butyl-4-hydroxy phenyl) propionic acid] pentaerythritol ester is made aging-proof agent, and dioctyl phthalate is made flexibilizer.
Water cleans up granite, and oven for drying is perhaps used in air dry then, and is standby;
Will other component except that building stones pour in the measurer successively and stir, then above-mentioned building stones are poured into, stir evenly, standby;
The above-mentioned material for preparing is injected mould, under the condition of 20～40 ℃ of temperature, make it tentatively finish synthetic reaction and first one-step forming;
Under the condition of 20～40 ℃ of temperature, humidity≤55%, said products is carried out maintenance in mould, the time is 8～12 hours, makes the moulding of goods primary solidification;
After the said products demoulding, keep flat and place aeration-drying place, under the condition of normal temperature and humidity≤55%, carry out maintenance, the time is 8～10 days, makes its thorough curing;
With said products roughly grind make its glossiness reach 40 the degree, finish grind again, make its glossiness reach 80 the degree more than, promptly get product of the present invention-artificial compounded granite shaped material.
Through check, every technical indicator of product of the present invention is as follows:
