本発明は塩化ビニル樹脂組成物に関し、より詳しくは、
難燃性で、かつ、火災時における腐食性ガス(塩化水素
ガス)の発生を抑制した塩化ビニル樹脂組成物に関する
。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a vinyl chloride resin composition, and more specifically,
This invention relates to a vinyl chloride resin composition that is flame retardant and suppresses the generation of corrosive gas (hydrogen chloride gas) in the event of a fire.

火災時の消火活動や避難に支障を来たすという難点があ
る。<Prior Art> In general, vinyl chloride resin compositions have excellent flame retardancy and are therefore used in a wide range of applications including electric wire coating materials. However, when such compositions burn in contact with flame, they generate hydrogen chloride gas, which is a corrosive gas.
This has the drawback of interfering with fire extinguishing activities and evacuation in the event of a fire.
この燃焼時における腐食性ガスの発生を抑制するために

て粒子径が004〜0.06μ程度の微粒子の軽質炭酸
カルシウムが配合されている。In order to suppress the generation of corrosive gas during combustion, light calcium carbonate has traditionally been blended into vinyl chloride resin compositions, but the smaller the particle size of this calcium carbonate, that is, the larger the surface area, the more It has the effect of increasing the capture rate of corrosive gas and suppressing the generation of corrosive gas, and therefore contains light calcium carbonate in the form of fine particles with a particle size of about 0.04 to 0.06 μm.
ところが、このような炭酸カルシウムは、高価であり、

等の機械特性、耐寒性が劣る等の難点がある。However, such calcium carbonate is expensive,
In addition, because they are fine particles, secondary agglomeration occurs during rolling, etc., resulting in poor dispersibility.As a result, so-called bumps (surface protrusions) occur during molding, and the tensile strength and elongation of molded products decrease. It has disadvantages such as poor mechanical properties and cold resistance.

しないことを見出し本発明を完成した。<Structure> As a result of repeated research in order to achieve the above-mentioned purpose, the present inventor discovered that aluminum hydroxide is a flame retardant and has the effect of reducing smoke generation during combustion (hereinafter referred to as smoke reduction effect). The present inventors discovered that the capture rate of hydrogen chloride gas, which is a corrosive gas, is not related to the particle size of calcium carbonate when they are combined in a specific ratio with calcium carbonate, which is a corrosive gas scavenger, and completed the present invention. .

以下、本発明の塩化ビニル樹脂組成物について詳細に説

In addition, the mechanical properties such as tensile strength and elongation of molded products and cold resistance are inferior.

ビニル樹脂組成物の混練時等の成形加工性に劣るととも
に、成形物の引張強度、伸び等の機械特性および耐寒性
に劣る。As described above, in the present invention, there is no need to use fine particles of calcium carbonate as in the past, so dispersibility is improved, and cold resistance and mechanical properties are improved compared to conventional vinyl chloride resin compositions. Furthermore, the generation of so-called bumps (surface protrusions) during molding is eliminated. The amount of calcium carbonate is 30 parts by weight per 100 parts by weight of polyvinyl chloride resin.
~100 parts by weight, preferably 40 to 70 parts by weight. If the blending amount of calcium carbonate is less than 30 parts by weight, the effect of reducing corrosive gas generated during combustion will be poor, and if it exceeds 100 parts by weight, molding such as when kneading vinyl chloride resin compositions will be insufficient. In addition to poor processability, molded products have poor mechanical properties such as tensile strength and elongation, and cold resistance.

If the amount of antimony trioxide is less than 2 parts by weight, the flame retardant effect will be poor, and if it exceeds 100 parts by weight, the molding processability during kneading of the vinyl chloride resin composition will be poor. Mechanical properties such as tensile strength and elongation, and cold resistance of colored products are inferior.

脂組成物が可塑化しすぎて混線や押出時等の成形加工性
に劣るとともに、成形物の機械特性に劣る。Commercially available plasticizers can be used as they are regardless of their type, such as phthalate esters such as dioctyl phthalate and diisodecyl phthalate, and trimellitic acids such as trioctyl trimellitate and triisononyl trimellitate. Examples include ester-based plasticizers, phosphate ester-based plasticizers such as cresyl diphenyl phosphate, and polyester-based plasticizers such as sepatic acid polyester and anopic acid polyester. The amount of the plasticizer to be blended is 30 to 150 parts by weight, preferably 50 to 80 parts by weight, per 100 parts by weight of the polyvinyl chloride resin. If the amount of the plasticizer is less than 30 parts by weight, the plasticity of the vinyl chloride composition will be insufficient, resulting in poor moldability during kneading and extrusion, as well as poor mechanical properties, cold resistance, and flexibility of the molded product. On the other hand, if the amount exceeds 150 parts by weight, the vinyl chloride resin composition becomes too plasticized, resulting in poor molding processability such as wire crossing and extrusion, as well as poor mechanical properties of the molded product.

It can be used in many ways, including as a covering material for electric wires and cables, as well as hoses and sheets. Furthermore, since the vinyl chloride resin composition of the present invention can use general-purpose calcium carbonate, it has better dispersibility than the fine particle calcium carbonate that has been used conventionally. In addition to improving cold resistance and mechanical properties, it is possible to reduce costs.
