Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl chloride resin composition having excellent long-term moldability and excellent surface smoothness of a molded article obtained.

[0002]

2. Description of the Related Art Vinyl chloride resins are inexpensive.
Because of its excellent physical properties such as impact resistance and heat resistance, and chemical properties such as solvent resistance and acid resistance, it is formed into various shapes by extrusion or injection molding, and is used in a wide range of applications such as building materials and pipe materials. Used in Due to the fact that the decomposition temperature and the molding temperature of the vinyl chloride resin are close to each other, even if only the vinyl chloride resin is extrusion-molded, a good molded product cannot be obtained. For this reason, when extruding the vinyl chloride resin, various additives such as a stabilizer and a solvent are blended.

However, when such a composition in which an additive is blended with a vinyl chloride resin is subjected to molding for a long period of time, a phenomenon occurs in which a solid adheres to the tip of a mold of a molding machine. This solid material, scratches, streaks, etc. on the molded product,
It adheres to the molded product itself. Therefore, in order to obtain a good molded product, it is necessary to frequently remove this solid from the tip of the mold, which has been a cause of a decrease in productivity.

Japanese Patent Application Laid-Open No. 4-178449 discloses a technique for reducing the adhesion of solids to the tip of a mold by using a needle-shaped material such as wollastonite or potassium titanate as an additive. Although it was disclosed, it could not be said that a sufficient effect was exhibited. In addition, Japanese Patent Laid-Open No. 1-1
No. 74551 discloses a technique for reducing the adhesion of solids to the tip of a mold by using titanium oxide and magnesium hydroxide as additives.
Titanium oxide was included in a large amount in the solid, and conversely, the adhesion of the solid could be increased.

Further, an example of blending basic lead phosphite is disclosed in JP-A-63-20343. However, in the process of treating with a titanate or silane coupling agent. In addition to the complexity, there is a problem that the long-term continuous productivity is inferior.

[0006]

The invention according to claim 2 (hereinafter referred to as the present invention 2) comprises 100 parts by weight of a vinyl chloride resin, 0.1 to 50 parts by weight of fly ash, and 0.1 to 1 parts of an acrylic processing aid.
0 parts by weight, 0.05 to 20 parts by weight of stabilizer, and 0.1 part of lubricant.
A vinyl chloride resin composition comprising from 02 to 10 parts by weight, wherein the lubricant comprises a glycerin ester of an unsaturated or saturated fatty acid having one or more hydroxyl groups per fatty acid molecule and an outer lubricant. It is a vinyl chloride resin composition. Hereinafter, the present invention 1 will be described.

The vinyl chloride resin used in the present invention 1 is not particularly limited. Examples thereof include a vinyl chloride homopolymer; a vinyl chloride monomer, and a polymerizable monomer having an unsaturated bond copolymerizable with the vinyl chloride monomer. And a graft copolymer obtained by graft copolymerizing a vinyl chloride monomer with the polymer. These may be used alone or in combination of two or more.

The polymerizable monomer having an unsaturated bond is not particularly limited as long as it has a radical-reactive double bond and can be copolymerized with a vinyl chloride monomer by a radical polymerization initiator. Α-olefins such as ethylene, propylene and butylene; vinyl esters such as vinyl acetate and vinyl propionate; vinyl ethers such as butyl vinyl ether and cetyl vinyl ether;
(Meth) acrylic acid esters such as methyl (meth) acrylate, ethyl (meth) acrylate, butyl acrylate, and phenyl methacrylate; aromatic vinyls such as styrene and α-methylstyrene; halogenation such as vinylidene chloride and vinylidene fluoride Vinyls; N-substituted maleimides such as N-phenylmaleimide and N-cyclohexylmaleimide; These may be used alone or in combination of two or more.

The polymer to be graft-copolymerized with the vinyl chloride monomer is not particularly limited as long as it is capable of graft-copolymerizing the vinyl chloride monomer. For example, ethylene-vinyl acetate copolymer, ethylene-acetic acid Vinyl-carbon monoxide copolymer, ethylene-ethyl acrylate copolymer, ethylene-butyl acrylate-carbon monoxide copolymer, ethylene-methyl methacrylate copolymer, ethylene-propylene copolymer, acrylonitrile-butadiene copolymer , Polyurethane, chlorinated polyethylene, chlorinated polypropylene and the like.
These may be used alone or in combination of two or more.

The above vinyl chloride resin has an average degree of polymerization of 50.
0 to 2000 are preferred, and more preferably 60
0 to 1400. If it is less than 500, the mechanical properties of the obtained molded article will be reduced, and if it exceeds 2,000, the melt viscosity at the time of molding will be high, and molding will be difficult.

[0013] The fly ash used in the present invention 1 is used for removing solid matter adhering to the tip of a mold or the like. The fly ash preferably has an average particle size of 0.1 to 30 μm. The average particle size is 0.
If it is less than 1 μm, it tends to be scattered when the raw materials are charged or mixed, and if it exceeds 30 μm, the appearance of the obtained molded article is impaired.

In the present invention 1, the amount of the fly ash is 0.1 to 50 parts by weight based on 100 parts by weight of the vinyl chloride resin. When the amount is less than 0.1 part by weight, the effect of removing solids is reduced. When the amount is more than 50 parts by weight, molding becomes difficult, and the appearance of the obtained molded article is impaired. Limited. Preferably, it is 1 to 20 parts by weight.

The acrylic processing aid used in the present invention 1 is not particularly limited, and may be, for example, a homopolymer or a copolymer of alkyl methacrylates such as methyl methacrylate, ethyl methacrylate, butyl methacrylate; Acrylates, copolymers with alkyl acrylates such as ethyl acrylate and butyl acrylate; copolymers of the above-mentioned alkyl methacrylates with aromatic vinyl compounds such as styrene, α-methylstyrene and vinyl toluene; alkyl methacrylates and acrylonitrile; Copolymers with vinyl cyanide compounds such as methacrylonitrile and the like can be mentioned. These may be used alone or in combination of two or more.

In the present invention 1, the addition amount of the acrylic processing aid is 0.1 to 10 parts by weight based on 100 parts by weight of the vinyl chloride resin. If the amount is less than 0.1 part by weight, the appearance of the obtained molded article is impaired,
If the amount exceeds 0 parts by weight, the load on the molding machine drive section at the time of molding increases, and molding becomes difficult, so that it is limited to the above range. Preferably, it is 0.3 to 6 parts by weight.

The paraffinic lubricant used in the present invention 1 is not particularly restricted but includes, for example, animal lubricants such as Chinese wax, vegetable lubricants such as carnauba wax, and mineral lubricants such as montan sun wax and lignite wax. And mineral lubricants such as microcrystalline wax and petrolatum. These may be used alone,
More than one species may be used in combination.

In the present invention 1, the amount of the paraffin-based lubricant is 0.02 to 10 parts by weight, preferably 0.1 to 10 parts by weight, based on 100 parts by weight of the vinyl chloride resin.
３3 parts by weight. When the addition amount is less than 0.02 parts by weight, the vinyl chloride resin composition has insufficient lubricity in the molding machine, the load on the molding machine rises remarkably, and discoloration or decomposition is easily caused by heat generation. If the amount exceeds 10 parts by weight, the lubricity becomes excessive, and the physical properties of the molded body deteriorate due to insufficient kneading.

Hereinafter, the present invention 2 will be described. The vinyl chloride resin, fly ash, and acrylic processing aid used in the second invention are the same as those used in the first invention.

The lubricant used in the present invention 2 comprises a glycerin ester of an unsaturated or saturated fatty acid having one or more hydroxyl groups per one molecule of fatty acid and an outer lubricant.

The reason why glycerin-based fatty acid esters exhibit remarkable performance in long-term moldability and surface smoothness in combination with other compositions has not been completely elucidated. It is presumed that it has an appropriate compatibility with the system resin and acts on the inner wall of the molding machine to suppress the adhesion of solids.

As the above fatty acids, those having one or more hydroxyl groups in one molecule are used. Since the hydroxyl group bonded to the fatty acid exerts a favorable affinity with the solid, it is necessary to have at least one hydroxyl group, and the more preferable number of hydroxyl groups per one molecule of the fatty acid is 1 to 3. If the number of hydroxyl groups exceeds 3, the affinity with the solid is sufficient,
Since the compatibility with the vinyl chloride resin is impaired, the effect is reduced.

The position at which the hydroxyl group is bonded to the carbon chain of the fatty acid is not particularly limited. In addition to the carbon adjacent to the carboxylic acid group and the terminal carbon, the fatty acid having an unsaturated bond may have an unsaturated bond. Adjacent carbon is not preferred. In all of these cases, steric hindrance of the hydroxyl group to another group and interaction between the functional groups cannot be ignored, and the hydroxyl group cannot maintain a favorable affinity with the solid.

The carbon number of the fatty acid in the glycerin fatty acid ester is not particularly limited, but is preferably in the range of 8 to 24, more preferably 12 to 18. If the fatty acid has less than 8 carbon atoms, the effect of the fatty acid residue is insufficient due to lack of lubricity, and if the carbon number exceeds 24,
When the compatibility of the glycerin fatty acid ester with the vinyl chloride resin falls outside the optimum range, the effect is reduced.

The saturated fatty acids having 8 to 24 carbon atoms include:
For example, caprylic acid (total carbon number = 8), pelargonic acid (9), capric acid (10), undecylic acid (1)
1), lauric acid (12), tridecylic acid (1)
3), myristic acid (14), palmitic acid (1)
6), stearic acid (18), nonadecanoic acid (1)
9), arachiic acid (20), behenic acid (22), and lignoceric acid (24).

The unsaturated fatty acids having 8 to 24 carbon atoms include, for example, oleic acid (total carbon number = 18), elaidic acid (18), undecylenic acid (11), setreic acid (22), elka Acid (22), pracidic acid (22), linoleic acid (18, unsaturated bond number 2),
Linoleic acid (18, the number of unsaturated bonds: 3). The number of unsaturated bonds per molecule of the unsaturated fatty acid is preferably 1 to 3, for example, arachidonic acid (2 carbon atoms).
If it is 0 and the number of unsaturated bonds is 4 or more as in 4), the thermal stability of the stabilizer is impaired, which is not preferable.

The above-mentioned glycerin fatty acid ester may be any one as long as at least one or more of the three hydroxyl groups of glycerin is esterified with a fatty acid. More preferably, two or more hydroxyl groups of glycerin are esterified by the fatty acid.
All of the hydroxyl groups are esterified by fatty acids.

If the number of hydroxyl groups of glycerin which is not esterified of the above-mentioned glycerin fatty acid ester is large, the sliding effect on the inner wall of the molding machine as a lubricant is not improved, and the more the hydroxyl groups of glycerin are esterified, the more the lubricant becomes. As an effect. The reason that the compatibility with the vinyl chloride resin is maintained even when all the hydroxyl groups of glycerin are esterified is that the fatty acid has a molecular structure having at least one hydroxyl group per molecule.

The at least one outer lubricant used in combination with the glycerin fatty acid ester is not particularly limited, but the following lubricants are preferred. Unless the outer lubricant is used in combination, the vinyl chloride resin composition sticks to the inner wall of the molding machine or is decomposed due to heat generated by friction with the inner wall, which is not preferable.

More preferred outer lubricants include, for example, waxes containing polyethylene and paraffin;
Ester waxes: organic waxes including stearic acid and ricinoleic acid. In particular, stearic acid, ricino-
Lulic acid is preferably used.

The total amount of the lubricant added is 10
The amount is 0.02 to 10 parts by weight, preferably 0.05 to 5 parts by weight, based on 0 parts by weight. If the amount is less than 0.02 parts by weight, the vinyl chloride resin composition has insufficient lubricity in the molding machine, the load on the molding machine rises remarkably, and discoloration and decomposition easily occur due to heat generation. If the amount exceeds 10 parts by weight, the lubricity becomes excessive, and the physical properties of the molded body deteriorate due to insufficient kneading.

The weight ratio of the glycerin fatty acid ester to the outer lubricant is preferably 15:85 to 95: 5, more preferably 25:75 to 90:10.

The stabilizer used in the present invention 2 is not particularly limited, and known stabilizers may be used. Preferable are white lead, basic lead sulfite, tribasic lead sulfate, dibasic lead phosphite, One or more lead-based substances (a) selected from dibasic lead phthalate, tribasic lead maleate, dibasic lead stearate, and lead stearate, and basic lead phosphite (b) Substance.

When the lead-based substance (a) and the basic lead sulfite (b) are not blended, desirable long-term moldability and surface smoothness as the essence of the present invention 2 cannot be obtained. That is,
A more preferred part of the gist of the present invention 2 lies in the discovery of specific long-term moldability development by a combination of a specific substance of a lead-based substance (a) and a basic lead phosphite (b). Although the mechanism for exhibiting a favorable effect is not clear, it is presumed that the maintenance of continuous productivity is a stationary screening effect due to the formation of a complex salt or the like between lead-based substances.

More preferred examples of the lead-based material (a) include one or more lead-based materials selected from basic lead sulfite, tribasic lead sulfate, dibasic lead phosphite, and dibasic lead phthalate. Substance.

The substance selected from one or more of the above-mentioned lead-based substances (a) and the basic lead phosphite (b) substance show an interaction if they are present in a small amount. : 9
The weight ratio may be in the range of 9.8 to 99.8: 0.2. A more preferable range of the weight compounding ratio is 1:99 to
90:10, and a more preferable range of the weight mixing ratio is 10:90 to 50:50.

If the weight ratio of at least one substance selected from the lead-based substances (a) is less than 0.2, the preferred interaction with the basic lead phosphite (b) is not sufficient, and the long-term continuous Moldability and good surface smoothness are not obtained, and even if the weight ratio exceeds 99.8, similarly long-term continuous moldability and
Good surface smoothness cannot be obtained.

The metal soap (c) used in the present invention 2 comprises:
Barium stearate, calcium stearate, barium oleate, calcium oleate, barium laurate, calcium laurate and the like are preferably used.
Particularly preferred are barium-based metal soaps, with barium stearate being most preferred. This is because a favorable thermal stabilizing effect is exhibited by the interaction between barium and lead.

A lead-based substance (a) used as a stabilizer,
The total amount of the basic lead sulfite (b) and the metal soap (c) was 0.1% based on 100 parts by weight of the vinyl chloride resin.
It is 0.5 to 20 parts by weight, preferably 0.1 to 10 parts by weight. If the amount is less than 0.05 part by weight, thermal stability is poor and discoloration and decomposition occur. If the amount is more than 20 parts by weight, physical properties of the obtained molded article are deteriorated.

The vinyl chloride resin composition of the present invention may optionally contain a modifier, a filler, an antioxidant, an antistatic agent, a pigment and the like. Further, a plasticizer may be added to such an extent that the effect of the present invention is not impaired.

The pigment is not particularly limited, and any of an organic pigment and an inorganic pigment may be used. Examples thereof include titanium oxide, carbon black, and zinc oxide.

The above-mentioned modifier is not particularly restricted but includes, for example, homopolymers such as methyl methacrylate, ethyl methacrylate and butyl methacrylate; acrylonitrile-butadiene-styrene copolymer, methyl methacrylate-butadiene-styrene copolymer, Chlorinated polyethylene, acrylic rubber and the like can be mentioned. The filler is not particularly limited, and includes, for example, calcium carbonate, talc, clay, mica, barium sulfate and the like.

The plasticizer is not particularly restricted but includes, for example, dibutyl phthalate (DBP), diheptyl phthalate (DHP), di-2-ethylhexyl phthalate (DOP), diisononyl phthalate (DINP), diundecyl phthalate (DUP) Phthalic acid esters such as dibutylbenzylphthalate (BBP); di-2-ethylhexyl adipate (DOA), diisononyl adipate (DINA), diisodecyl adipate (DID)
And adipic acid esters such as A).

The vinyl chloride resin composition of the present invention may be in the form of powder or granulated pellets during molding. The method for obtaining a molded article from the vinyl chloride resin composition of the present invention is not particularly limited, and various conventionally known molding methods can be employed. For example, when forming into a pipe, a deformed product, or the like, it can be formed by extrusion molding, and when forming into a joint or the like, it can be formed by injection molding.

The extruder used for the extrusion molding is not particularly limited, and any suitable one can be used. Examples thereof include a single screw extruder, a conical twin screw extruder, and a parallel twin screw extruder. Can be In general, in the case of hot runner injection molding, since the runner portion is heated and the resin is retained, adhesion of solid matter is likely to occur, but the vinyl chloride resin composition of the present invention is preferably molded by hot runner injection molding. be able to.
