Description

Regular form of aluminosilicate and its use {REGULARLY-SHAPED ALUMINOSILICATE AND ITS USE}

The present invention relates to aluminosilicates in regular form. More specifically, the present invention relates to aluminosilicates in regular form which are excellent in pigmentability, can be easily dispersed in resins, facilitate mixing operations, and are useful as admixtures of resins or coating materials. .

There is a need for inorganic fillers which have a predetermined particle shape as fillers for various polymer films, resins or rubbers and rarely cause secondary agglomeration.

Accordingly, zeolites are known which have a predetermined particle shape in the resin and which impart anti-sticking action when mixed. As an example, according to Japanese Patent Publication No. 16134/1977, antiblocking of biaxially oriented films was enhanced by adding zeolite powder having an average particle diameter of 20 microns or less to polypropylene in an amount of 0.01 to 5% by weight. .

In addition, Japanese Laid-Open Patent Publication No. 36866/1986 has a molar ratio of Al ₂ O ₃ : SiO _{2 on} one side not longer than 5 microns, 1: 1.8 to 1: 5, substantially amorphous when observed by X-ray diffraction, and a BET specific surface area. Alumina-silica resin admixtures composed of primary cubic particles of 100 m 2 / g or less are disclosed.

Nepeline cyneite, a natural silicate, is a mineral produced in Canada, and the powder obtained by pulverizing and classifying it is commercially available under the trade name "Minex" and mixed with resin (Japanese Laid-Open Patent Publication No. 234984/1990).

However, zeolites absorb moisture called zeolite. When the resin is mixed with zeolite and heated, bubbles are formed while the above-mentioned moisture is released. Therefore, an aluminosilicate admixture which is inert and shows little adsorption is needed.

The above-mentioned amorphous aluminosilicate resin admixture contains particles of a certain form without the base component of the zeolite, can lower the pigment performance of the molded resin particles, and also exhibits less surface activity and adsorption compared to the zeolite, but is still hygroscopic It has If the mixture is mixed with a resin after being left under conditions of very high humidity, problems such as bubble formation occur.

Moreover, the product obtained by pulverizing and classifying nephelin cyneite, a natural aluminosilicate mineral, exhibits very small hygroscopicity and is therefore used as a mixture of resins or coating materials.

However, the product particles exhibit a non-uniform shape with a wide distribution of particle sizes. Therefore, this admixture cannot meet the purpose to impart the desired anti-sticking property by mixing in a relatively small amount. Moreover, natural products contain many impurities, leaving room for improvement in terms of quality diversity. The particles also have sharp edges specific to the mechanically milled product, indicating abrasiveness.

Accordingly, a first object of the present invention is to provide an aluminosilicate in a regular form having a predetermined composition, containing particles in a regular form, exhibiting a symmetric particle size distribution and exhibiting low hygroscopicity and excellent pigment performance.

It is a second object of the present invention to provide a mixture for a resin or a coating material which has a high pigment volume concentration, which can be easily mixed and dispersed in the resin and the coating material, and which allows the mixing operation to be preferably performed.

According to another aspect of the present invention, there is provided a mixture for resins, a mixture for coating materials, and a mixture for crystalline glass, containing the aluminosilicate in the above-described regular form.

It is known that the crystalline structure of zeolite changes to one of nephelin type or carnegiate type when fired at high temperature. However, it was not thought that nephelin or carnegiate formed by this zeolite transition was a useful substance.

The aluminosilicate of the regular form of the present invention has a nephelin type or carnegiate type crystal structure, and has a chemical composition represented by the above formula (1) and a particle form of a cubic or spherical regular form.

The chemical composition of Formula 1 described above corresponds to the chemical compositions of Form A and Pc zeolites. The present invention has been successful in synthesizing cubic or spherical regular nephelin or carnegiate particles by changing the crystal structure of the A-type and Pc-type zeolites into one of nephelin type or carnegiate type.

In the accompanying drawings, Figure 1 is a scanning electron micrograph showing the structure of the aluminosilicate particles of the regular form of the present invention, Figure 2 is a scanning electron micrograph showing the structure of the conventional nephelin particles. Comparing these electron micrographs, the conventional nephelin particles produced by pulverization are irregular in shape and exhibit a polishing form similar to that of crushed glass surfaces. In addition, the particle size is irregular. On the other hand, the aluminosilicate of the regular form of the present invention comprises particles of a regular form of cubic or spherical in shape with symmetry.

The aluminosilicate particles of the regular form of the present invention are not particularly limited but have an average particle diameter of generally 0.1 to 30 μm, in particular 0.5 to 25 μm. The fineness (DP) of the particle size distribution of known nephelin cyneite is usually 3 or more. However, the degree of sharpness (DP) of the aluminosilicate in the regular form of the invention is generally between 1.2 and 2.9, indicating a symmetrical particle size distribution. Therefore, the powder has good fluidity and is well dispersed in the resin and the coating material.

It is an X-ray diffraction image of a known nephelin cysteine. The X-ray diffraction image of FIG. 3 corresponds to the nephelin ICDD19-1176, 33-1203, 35-424 peak, and the X-ray diffraction image of FIG. 4 corresponds to the Carnegieite ICDD11-220, 11-221 peak, while the conventional Natural minerals contain many impurities as shown in FIG. 5. Therefore, the resin and the like mixed with the aluminosilicate of the regular form of the present invention are not affected by impurities.

The aluminosilicate of the regular form of the present invention is calcined to obtain crystals of nephelin type or carnegiate type, which have a fairly thick apparent specific gravity of about 0.3 to 0.8 g / cm 3, in particular about 0.4 to 0.6 g / cm 3. Excellent pigment properties with oil oil absorption of 50 ml / 100 g or less. Therefore, the aluminosilicate in the regular form of the present invention can be easily mixed with the resin or the coating material and shows excellent workability.

In addition, the aluminosilicate in the regular form of the present invention has a refractive index of 1.46 to 1.56, which is similar to the refractive index of the resin. Thus, resins mixed with aluminosilicates in regular form do not lose transparency. Moreover, even when used as a sieving (extender pigment), the transparent coating material does not lose its transparency.

The regular form of the aluminosilicate of the present invention has a very small hygroscopicity, absorbing up to 1% of moisture when exposed for 48 hours in an atmosphere having a relative humidity (RH) of 90% and a temperature of 20 to 25 ° C. do. Therefore, the resin mixed with the regular form of aluminosilicate does not cause the problem of bubble formation, and thus no moisture proof measures are required before mixing.

The aluminosilicates in the regular form of the present invention can be produced by firing synthetic Type A or Pc zeolites generally at temperatures above 800 ° C.

Type A and Pc type zeolite particles supplied as starting materials are well known and preferably have a chemical composition falling within the range of the general formula (1).

The starting material type A zeolite is, for example, by mixing sodium silicate or active silicate gel, sodium aluminum and sodium hydroxide to form a gel of alkali aluminosilicate that satisfies the composition shown in Table 1 below, and then homogenize the gel. The gel is synthesized by crystallization at a temperature of 80-200 ° C. under atmospheric or hydrothermal conditions:

Ingredient ratio Molar ratio Na ₂ O / SiO ₂ 0.06 to 3.4 SiO ₂ / Al ₂ O ₃ 0.8 to 18 H ₂ O / Na ₂ O 4 to 300

In addition, according to the present invention, the starting material Pc zeolite is synthesized by lowering the SiO ₂ / Al ₂ O ₃ molar ratio by 2 to 3.6. Preferred Pc zeolites have the composition shown in Table 2 below:

SiO ₂ 50 to 40% by weight Al ₂ O ₃ 23 to 35 wt% Na ₂ O 15 to 19% by weight

Pc-type zeolites are synthesized by mixing sodium silicate or active silicate gels, sodium aluminate and sodium hydroxide to form alkali aluminosilicate gels that meet the conditions shown in Table 3 below:

Ingredient ratio Molar ratio Desired molar ratio Na ₂ O / SiO ₂ 0.2 to 8 0.5 to 2 SiO ₂ / Al ₂ O ₃ 2 to 3.7 2.5 to 3.1 H ₂ O / Na ₂ O 20 to 200 30 to 100

In order to prevent the formation of A-type and X-type zeolites as by-products, the reaction is strongly stirred at a temperature of 80 ° C. or higher, preferably 80 to 200 ° C. under atmospheric pressure or hydrothermal conditions, so that crystallization occurs under uniform conditions. It is important to do. This makes it possible to synthesize Pc zeolite in pure form.

Before firing, it is preferable that the free alkalis of the formed A-type and Pc-type zeolites are sufficiently washed or slightly treated with an acid to remove as much of the free alkali component as possible.

In order to produce aluminosilicates in a regular form other than the Na type, the A or Pc zeolites obtained by the above-mentioned method are contacted with an aqueous solution of K, Ca, Mg or Zn water-soluble salts to exchange ions. Water-soluble salts may use inorganic salts such as chlorides, nitrides or sulfides, or organic salts such as acetates and toluene sulfonates. Ion exchange is preferably performed at a temperature from room temperature to 90 ° C. using an equivalent amount or more of water soluble salts. The advantage of improving the exchange rate is obtained when the ion exchange treatment is carried out under heating conditions.

Form A and Pc zeolites are calcined at a temperature of at least 800 ° C, in particular at 800 to 1500 ° C. The crystal structure of the product depends on the firing temperature. For type A zeolites, carnegiate is formed at a temperature of about 800 ° C., nephelin is formed at a temperature of at least 850 ° C., and carnegiate is formed again at a temperature of at least 1300 ° C.

Firing can be carried out using a fixed bed type, moving bed type or fluidized type firing furnace. The heating source may be various baking gases, infrared rays, or the like. The firing time may generally vary depending on the type of furnace and the type of crystal, but is typically about 0.5 to about 4 hours. FIG. 6 shows a change in refractive index with a change in firing time when firing the A-type zeolite (Sample No. AZ-1) of Example 1 shown below in a 900 ° C electric furnace.

The nephelin type or carnegiate type regular particles obtained by sintering showed symmetrical particle size distribution when compared to the A and Pc zeolite particles. This is because the fine particles included in the present application are sintered, and shrinkage of the zeolite particles may also be a factor.

The aluminosilicate in the regular form thus formed is used, if necessary, as a mixture for resins, coating materials or crystalline glass after treatment such as grinding, classification, and the like.

Moreover, a variety of post and surface treatments are carried out as needed for the aluminosilicate particles in regular form.

If the product is strongly alkaline, for example, the product is washed with water or slightly treated with acid to adjust the pH at the time of dispersion in water. It is preferred that the pH of the 5% aqueous suspension of aluminosilicate in regular form has 8 to 11.

The acid used may be an inorganic acid or an organic acid, but is not particularly limited thereto. However, from an economic point of view, it is preferable to use inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid or phosphoric acid.

According to the present invention, the surface of the aluminosilicate particles in the regular form may be coated with fatty acid, metal soap, resinous soap, various resins or waxes, silane type, titanium type or zirconium type coupling agent, or silica coating as needed. have.

Although not generally necessary, one or more metal components selected from the group consisting of alkali metals, alkaline earth metals, Ti, Zr, Al and Zn may also be applied to modify the surface of the amorphous regular particles. In addition, the refractive index of the product of the present invention can be adjusted at the time of surface modification, and the refractive index of the resin can be adjusted by mixing the product. For example, it may be surface coated or surface treated with titanium oxide, silicon oxide, zirconium oxide, zinc oxide, barium oxide, magnesium oxide or calcium oxide.

The aluminosilicates in the regular form of the present invention can be used as resin blends for various resins, such as olefin resins such as polypropylene, polyethylene, crystalline propylene-ethylene copolymers, ion-crosslinked olefin copolymers, ethylene-vinyl acetate copolymers; Thermoplastic polyesters such as polyethylene terephthalate and polybutylene terephthalate; Polyamides such as 6-nylon, 6,6-nylon; Chlorine-containing resins such as vinyl chloride resin and vinylidene chloride resin; Polycarbonates; Polysulfones; And polyacetals to impart antitack or slipperiness to molded resin products, such as biaxially stretched films. It is also possible to use the aluminosilicates of the regular form of the invention as fillers for increasing the weight of the molded resin product, adjusting the hardness, increasing the strength as well as imparting heat resistance.

Preferred thermoplastic resins for mixing with aluminosilicates in regular form as anti-sticking agents are olefin resins. Examples include low density, medium density or high density polyethylene, isotactic polypropylene, syndiotactic polypropylene, or polypropylene copolymers which are copolymers of such ethylene or α-olefins, linear low density polyethylene, ethylene-propylene copolymers, Polybutene-1, ethylene-butene-1 copolymer, propylene-butene-1 copolymer, ethylene-propylene-butene-1 copolymer, ethylene-vinyl acetate copolymer, ion crosslinked olefin copolymer (ionomer) and ethylene- Acrylic ester copolymers, which can be used alone or in the form of a mixture of two or more thereof.

Olefin polymers can be produced using so-called Ziegler catalysts containing halogen-containing transition metal compounds and organoaluminum compounds or catalysts containing cyclopentadienyl skeleton-containing complexes of transition metals such as titanium or zirconium and organoaluminoxane compounds. Can be.

The amount added to the resin is generally appropriately selected from the range of 0.01 to 100 parts by weight per 100 parts by weight of the resin, and may vary depending on the use thereof.

Here, the resin mixture of the present invention is neutral, inert to other resin mixtures, does not decompose the resin, does not color, does not impair the properties of the other resin mixture, or does not impair the properties of the resin.

Examples of the antioxidant include phenolic antioxidants, and examples thereof include 2,6-di-t-butyl-4-methylphenol and tris (3,5-di-t-butyl-4-hydroxybenzyl) Isocyanurate (Irganox 3114 available from Ciba Geigy Company), 2,2'-methylenebis (4-ethyl-6-t-butylphenol), n-octadecyl-3- (3 ', 5'- Di-t-butyl-4'-hydroxyphenyl) propionate (Irganox 1076 available from Ciba-Geigy Company), 4,4'-thiobis (3-methyl-6-t-butylphenol), tetrakis [Methylene-3- (3 ', 5'-di-t-butyl-4'-hydroxyphenyl) propionate] methane (Irganox 1010 available from Ciba-Geigy Company), 4,4'-butylidene Bis (3-methyl-6-t-butylphenol), 2,2'-methylenebis (4-methyl-6-t-butylphenol), N, N'-hexamethylenebis (3,5-di-t -Butyl-4-hydroxyhydrocyanamide) (Irganox 1098 available from Ciba Geigy Company), triethylene glycol bis [3- (3'-t-butyl-5'-methyl-4-hydroxyphenyl) prop Cypionate], Bis (3,5-di -t- butyl-4-hydroxybenzyl ethyl phosphonate) a mixture of calcium and PE wax (weight ratio 1: 1) there are.

The phenolic antioxidant is preferably added in an amount of 0.01 to 0.3 parts by weight per 100 parts by weight of the resin. If it is less than the amount in this range, there is no antioxidant effect. If the amount exceeds 0.3 parts by weight, the resin is colored yellow after being stored for a long time, or a proliferative action occurs on the film surface, impairing transparency or barrier property.

Examples of phosphorus antioxidants include trimethyl phosphite, tri-n-butyl phosphite, tridecyl phosphite, tris (2-ethylhexyl) phosphite, trinonyl phosphite, tricetyl phosphite and dilauryl hydrogen Phosphite, Tricyclohexyl Phosphate, Triphenyl Phosphate, Tribenzyl Phosphate, Tricresyl Phosphate, Tri-p-nonylphenyl Phosphate, Diphenyldecyl Phosphate, Tris (dinonylphenyl) Phosphate, Tris (2,4-di-t-butylphenyl) phosphite, tris (4-α-methylbenzylphenyl) phosphite, tris (octylthioethyl) phosphite, tris (octylthiopropyl) phosphite, tris (cresyl Thiopropyl) phosphite, tris (3,5-di-t-butyl-4-hydroxyphenyl) phosphate, tetraphenyldipropylene glycol diphosphate, 4,4'-butylidenebis (3-methyl-6 -t-butylphenylditridecyl) phosphite, 1,1,3-tris (2-methyl-4-ditridecylphosphite-5-t-butylphenyl) butane, non S (2-chloropropyl) pentaerythritol diphosphatio, bisphenylpentaerythritol diphosphate, bisstearylpentaerythritol diphosphate, trilauryltrithio phosphite, tetrakis (2,4-di -t-butylphenyl) 4,4'-biphenylene diphosphate, and the like.

It is preferable to add a phosphorus antioxidant in the quantity of 0.01-0.2 weight part per 100 weight part of resin. When the addition amount is less than this range, the antioxidant effect and the yellowing prevention effect of the resin do not appear. When the addition amount exceeds 0.3 parts by weight, black spots and metal corrosiveness may increase.

In order to improve the processability of a resin composition, all the lubricants used for a polyolefin film can be used. Examples of such lubricants include (a) hydrocarbon-based lubricants such as flowable natural or synthetic paraffins, microwax, polyethylene waxes, and chlorinated polyethylene waxes, (b) fatty acid-based lubricants, such as stearic acid and lauric acid, (c) palmitic Acid amides, ecylate amides, methylenebis stearamides, ethylenebis stearamides, erucic acid amides, stearic acid amides, oleic acid amides, behenic acid amides, N-stearyl butyric acid amides, N-stearyl caprylic acid amides , N-stearyl lauric acid amide, N-stearyl stearic acid amide, N-stearyl behenic acid amide, N-oleyl oleic acid amide, N-oleyl behenic acid amide, N-butyl erucic acid amide, N Octyl erucic acid amide, N-lauryl erucic acid amide, ethylenebis oleic acid amide, hexamethylenebis oleic acid amide, N, N'-dioleyl adipic acid amide, and N, N'-dioleyl three Esters such as butyl stearate, cured castor oil and ethylene glycol monostearate, such as sacid amide, (e) alcohol based lubricants such as cetyl alcohol and stearyl alcohol, (f) lead stearate, stearic acid Metal soaps such as calcium acid, and (g) mixtures thereof.

Lubricants, particularly fatty acid amide lubricants, are preferably used in amounts of 0.01 to 0.3 parts by weight per 100 parts by weight of the resin. If the amount is less than the above-mentioned range, no slipperiness is formed. If the amount is larger than the above-mentioned range, the film surface is bleached due to the proliferation phenomenon and the transparency is lost.

The aluminosilicates in the regular form of the present invention can be mixed with various coating materials as admixtures such as sieving (extender pigments), rheology-adjusting agents, anti-glossing agents.

Example 1

Hereinafter, a method for preparing a resin mixture and a coating material mixture comprising a fine powder of aluminosilicate (nephelin type, carnegiate type) of the regular form of the present invention having high particle size symmetry and low hygroscopicity is described. .

Preparation of aluminosilicate in regular form and its properties

Sodium silicate aqueous solution prepared from sodium silicate collet with A-type zeolite particles having a cubic or spherical regular form having a molar ratio of SiO ₂ / Al ₂ O ₃ of ₂ , which is a starting material of the present invention (SiO ₂ = 22 weight %, Na ₂ O = 7.2 wt%), aqueous sodium aluminate solution (Al ₂ O ₃ = 25 wt%, Na ₂ O = 19 wt%) and sodium hydroxide.

The sodium silicate solution and the sodium aluminate solution were mixed slowly while stirring under the following molar composition ratio, but the total amount of the reaction solution was mixed so that the total amount of the reaction solution was 5 kg in a stainless steel vessel to form a uniform sodium aluminosilicate gel as a whole. :

Na ₂ O / SiO ₂ = 1 to 1.5

SiO ₂ / Al ₂ O ₃ = 2 to 2.5

H ₂ O / Na ₂ O = 70

The gel was then vigorously stirred at a temperature of 80 ° C. to 95 ° C. for about 2 hours to form particles of a regular form of A-type zeolite crystals, followed by filtration and washing to remove the free alkali component, thereby obtaining about 30% moisture. A cake-like product (AZH) containing was obtained. Some of this product was dried at 110 ° C. (Sample No. AZ-1).

The AZH was then calcined in an electric furnace at 900 ° C. for 2 hours and then dry-milled using a ball mill (Sample No. NP-1, nephelin type). Some of this product was wet-milled again and then stearic acid was added to it in an amount of 1% per solids content. The mixture was heated to 80 ° C., stirred for 1 hour, filtered, washed with water, dried at 100 ° C., triturated using a small sample mill and fractionated (sample number NP-2, nephelin type).

The AZH was again calcined at 700 ° C., 800 ° C., 1000 ° C. and 1400 ° C. to prepare the product in the same manner as in Sample No. NP-1 (Sample No. NP-3, A-type Zeolite; NP-4, Carnegie Eye) Type; NP-5, nephelin type; NP-6 carnegiate type). NS is now commercially available as Nepeline cyneite produced in Canada and used as a comparative example to aid in the understanding of the present invention.

Products prepared by partial calcination of AZH at 900 ° C. followed by washing with 5% sulfuric acid comprise particles of the preferred regular form of the nephelin type which meet the object of the present invention. As a reference example, regular aluminosilicates of low hygroscopicity were prepared by preparing AZH in the form of a water-dispersion slurry and calcining about ½ of sodium in zeolite with an aqueous solution of calcium chloride and an aqueous solution of magnesium chloride and then calcining. .

Example 2

A-type zeolite particles as starting materials of the present invention, sodium silicate aqueous solution (SiO ₂ = 22 wt%, Na ₂ O = 7.2 wt%) prepared by sodium silicate cullet, sodium aluminate aqueous solution (Al ₂ O ₃ = 25 Wt%, Na ₂ O = 19 wt%) and sodium hydroxide.

The sodium silicate solution and the sodium aluminate solution were mixed together under the following molar composition ratios, but the total amount of the reaction solution was mixed such that the total volume of the reaction solution was 5 kg in a stainless steel vessel to form a homogeneous sodium aluminosilicate gel:

Na ₂ O / SiO ₂ = 1.6

SiO ₂ / Al ₂ O ₃ = 1.8

H ₂ O / Na ₂ O = 120
