Description

TECHNICAL FIELD ... This invention relates to a body. Gloves that can be discarded in more detail (the conventional technique of vinyl paste resin group: in a vinyl chloride paste resin composition and its formation, the present invention relates to a kind of Disposable gloves) and other chlorine products and disposable gloves. The thickness in the center of the palm used in food and medical fields is about 80 ~ 15. Disposable gloves after use refer to gloves that can be discarded after use, gloves around Ain.

On the make-up: 'The manufacturing of disposable gloves after use is made of chloroethene_ ί 成 物' By immersing a hand mold such as ceramics at 50 ° c and I occupying about 70 ^ 00mPa.s Plastisol (hereinafter referred to as sol) After drying up, remove the excess sol, gel, and then make the 2 processing method. In the past, phthalate plasticizers, such as monooctyl phthalate (DOP), or phthalic acid, have generally been used as disposable vinyl paste resin compositions for disposable gloves for disposable gloves. Di-n-butyl ester (DBp) and the like. However, dioctyl phthalate (DO), butyl phthalate (BBP), di-n-butyl phthalate (DBp), and di-n-pentyl phthalate (DPP) ), Dipropyl phthalate (DpRp), phthalate dihydrocyclohexyl (DCHP), or phthalate diethyl phthalate (ρΕρ) is suspected to be Substances that disturb endocrine action (so-called environmental hormones) are used in food and medical fields where disposable gloves can be discarded. They replace these phthalate-based plasticizers and are highly hygienic.

Japanese Patent Application Laid-Open No. 20-226482 describes a sol composition containing polyvinyl chloride = tributyl citrate, but σ (ATBC), 9 | ^ D〇p is easy to volatilize when heated. The hardness (100% modulus) of the molded product is 4 low. This is because the characteristics and feel of the molding ασ are changed. The quantity is 500 and the pW is described in JP 57-3846. Add 1 molecule to help, for example, a 'agent' that contains adipic acid dicapryle! , j such as diisononyl adipate alone (dina) I y; initial gelation is slower than DOP, when the gel is melted, two: two times two times, and there are many cases of uneven thickness of the product Shape. If you mix the right and large s, there is a problem that the juice tends to flow out. The term "initial gelation" refers to a speed at which the thickener is thickened by heating and the gluten stops flowing.扪 to paste: ΪFair No. 05-13175 describes that it contains polyvinyl chloride ^ It is a hardener, such as tert-butyl perbenzoate, which is formed by ρ. However, it is a benzoate-based plastic. Chemical agents, such as the case of using Sebeki (manufactured by Asahi Denka Kogyo Co., Ltd.) alone, have good miscibility with Titanium and Titanium, and the initial gelation is much faster than DOP. Viscosity over time The change has increased significantly, so it is necessary to adjust the security conditions of the sol, and it is also prone to processing problems. ‘’ Glue is easily entangled with air bubbles, and because the air bubbles involved are difficult to remove teeth, pinholes tend to occur during glove molding.

Furthermore, the present invention relates to a disposable glove which is obtained by subjecting the aforementioned vinyl chloride-based paste resin composition to molding. Purposes of a preferred embodiment of the present invention are: a vinyl chloride-based paste resin used in the present invention may 2066-4480-Pf.ptd 8 Shang 々 page 4124 according to the following method

Aqueous media such as mixed monomers or monomers that can be copolymerized with chloroacetin monomers, emulsifiers, etc., are used in emulsion polymerization of water-soluble poly-oil-soluble seed crystals, or After the polymerization, the lactate and # / ++ are finely suspended and polymerized. Secondly, it can be obtained by the method of the aforementioned paste preparation = drying, etc. So here, if flat = fat; it has an average particle size of 0. The particles of Bu 5 "potential; if the average particle _ :: "m is small," the viscosity of the sol tends to increase. If the upper V m is large, there are monomers that can be copolymerized with vinyl chloride monomers that gel and slow down the melting rate. Generally, if t monomers are used, the ether dioctane = propane is not particularly limited. , Isobutylene and other dilute hydrocarbons; isobutyl acetofluorene-pentin & vinyl ethers and other vinyl ethers. No. 72 is the degree of polymerization of Tuheshu's vinyl chloride paste resin. It is best to have a shot value of ~ 80. Resins having a lower κ value than 70 will tend to reduce the tensile strength of the molded product. In addition, resins with a higher κ value than 80 have a tendency to decrease polymerization productivity and increase costs. Here, the K value of the resin is measured in accordance with ISO 1 628-2. The vinyl chloride-based paste resin may be a vinyl chloride-based paste resin alone or a vinyl chloride-based blend resin may be added as needed. The vinyl chloride-based blend resin can be obtained by the following method. First, 'p-vinyl chloride monomer, or a mixture of monomers copolymerizable with vinyl chloride monomer', in an aqueous medium containing a polymer-based suspension stabilizer, etc., in oil ^ 1224124 V. Description of the invention (6) Initiation of sexual polymerization Suspension polymerization is performed in the presence of an agent. Next, it is obtained by dehydrating the polymerized slurry with a centrifugal dehydrator or the like, and then performing a method such as air drying or flow drying. The aforementioned blended tree obtained as described above has particles having an average particle diameter of 10 to 7 m. Here, if the average particle diameter is smaller than 10 ', it tends to be difficult in industrial production; if the average particle diameter is larger than 7 0 // m', sedimentation easily occurs in a low viscosity sol, and gelation I melts. Slower trend. The aforesaid gaseous vinyl-based blended tree is used in combination with the gaseous vinyl-based pasty resin as necessary for the purpose of improving the fluidity of the pasty sol. As the polymerization degree of the vinyl chloride-based blended resin, a K value of ~ 70 is preferably used. If the κ value is lower than 60, the tensile strength tends to decrease; the right K value j; b70 ^ higher, there is a tendency for gelation and slower melting speed. Then, the vinyl chloride-based paste resin and the vinyl chloride-based blended resin system have been widely used in the past. Various grades of products can be obtained from the market, and any of them can be used in the invention. — Babenfa ㈣ plastic ㈣ 相 相 I gas, B material, paste tree two denier knife, the use of 50 ~ 120 weight points is better, and 70 ~ 100 weight points are sticky; and t I the right belching dose ratio is 5 〇If the weight is small, it is tilted for processing. ; Many thinners, even the hardened holes of the molded product cause the defective rate to increase: = thinner and thinner, because the product produces needles of 20 weight points, and because of the tendency of the mouth to become forceful. . Conversely, if it exceeds the strength of the pour product with the deterioration of the value of the product and the outflow of the plasticizer juice, for the present invention, the plasticizer is described as A below, and the citric acid ester-based plasticizer (Α
