Abstract

PURPOSE:To provide the packing material which has excellent resilience, mechanical strength and weatherability, good moldability and excellent flame resistancy and is adequate for window glass. CONSTITUTION:The flame resistant packing material (glazing channel) is molded by kneading 20 pts.wt. dioctyl phthalate, 30 pts.wt. tricresyl phosphate, 60 pts.wt. calcium carbonate, 15 pts.wt. antimony trioxide, and 3 pts.wt. calcium-zinc composite stabilizer with 100 pts.wt. mixture composed of 50 pts.wt. vinyl chloride/ethylene copolymer having 7wt.% ethylene content and 1400 average degree of polymn. and 50wt.% chlorinated polyethylene having 35wt.% chlorine content. This flame resistant packing material (glazing channel) does not change its shape and its dimensional change is <=1.2 times in a combustion test (consisting in bringing the material into content with the flame of a Bunsen burner for 10 seconds and parting the material therefrom for 10 seconds, then bringing the material into contact with the flame for 10 seconds). The material blackens and does not generate a spacing between aluminum sash and glass plate in the state of maintaining the molded shape in a practicable use test (consisting in heating the material for 2 hours at 300 deg.C).

The flame resistance is a property that, when the packing material comes into contact with a flame, it does not burn or deform and flow, but blackens in its original shape. This flame resistance is

That is, when the window glass comes into contact with the flame in a fire, if the packing material deforms and flows, air flows between the window frame and the glass plate to strengthen the fire. However, when the packing material is only blackened in its original shape, air flow is prevented from flowing between the window frame and the glass plate, which is useful for preventing fire spread.

However, it is not easy to find a material that satisfies the above-mentioned various properties. Up to now, polyvinyl chloride has been exclusively used as a resin that constitutes a packing material for window glass, and a plasticizer and an inorganic filler have been mixed therein.

However, a packing material using polyvinyl chloride as a resin component could not be made to have a good shape retention during heating and combustion. In order to eliminate such a defect, it has been proposed to use a graft polymer obtained by graft-polymerizing vinyl chloride with an ethylene-vinyl acetate copolymer as a resin constituting the packing material (Japanese Patent Publication No. -9075 gazette).

Further, it has been proposed that a chlorinated polyethylene is blended with a vinyl chloride resin to improve the shape retention during heating and combustion (see Japanese Patent Laid-Open No. 60-226542).

However, when the above graft polymer is used, a lump is formed in the mixture when the compound is mixed with an essential plasticizer to be blended with the graft polymer, so that the molding machine is used. It is difficult to supply the raw materials smoothly, and there is a problem to be improved in terms of moldability. Further, the graft polymer has a problem that it is relatively expensive.

When a chlorinated polyethylene is mixed with a vinyl chloride resin, a small amount has a low flame resistance, and a large amount of a chlorinated polyethylene must be mixed in order to sufficiently retain the shape retention during heating and combustion. However, if mixed in a large amount, the mechanical strength will decrease, and thus there is a problem as a packing material for window glass.

Moreover, it is intended to provide a packing material which has excellent flame resistance and is suitable for fitting a glass plate to a window frame.

The vinyl chloride-ethylene copolymer used in the present invention has an ethylene component of 4 to 10% by weight. The reason for this is that if the ethylene content is less than 4% by weight, the compatibility with chlorinated polyethylene will be poor and the mechanical strength will decrease. Conversely, if the ethylene content is more than 10% by weight, the copolymer This is because the tackiness of the product increases and the moldability deteriorates. Regarding the degree of polymerization of this copolymer, it is preferable to use one having an average degree of polymerization of 800 to 2000 from the viewpoint of mechanical strength and moldability.

The chlorinated polyethylene used in the present invention has a chlorine content of 20 to 40% by weight. The reason is,
When the chlorine content is less than 20% by weight, the compatibility with the vinyl chloride-ethylene copolymer is deteriorated, so that the plasticizer is likely to bleed from the composition, resulting in a decrease in mechanical strength and conversely. When the chlorine content is more than 40% by weight, the composition tends to stick to the metal part of the molding machine during molding, and the hardness of the composition becomes high, resulting in poor moldability. Moreover, the thermal stability also deteriorates.

In the present invention, the mixing ratio of the above vinyl chloride-ethylene copolymer and chlorinated polyethylene is 50 to 70% by weight for the former and 50 to 30% by weight for the latter.
The total is 100% by weight. The reason is that if the mixing ratio of chlorinated polyethylene is less than 30% by weight, the shape retention during heating and combustion deteriorates, and conversely, if the mixing ratio of chlorinated polyethylene is more than 50% by weight, moldability is improved. Is deteriorated, the appearance of the product is impaired, and the shrinkage rate of the product is increased, which causes inconvenience as a packing material.

As the plasticizer, all the plasticizers generally used for polyvinyl chloride can be used. For example, various plasticizers such as phthalic acid type, phosphoric acid type, fatty acid type, epoxy type and polyester type can be used. Among these plasticizers, the phosphoric acid-based ones are preferably used because the object of the present invention is the problem of flame resistance. As a specific example, it is preferable to use tricresyl phosphate, trioctyl phosphate, or the like.

The plasticizer is used in an amount of 30 to 1 with respect to 100 parts by weight of a mixture of vinyl chloride-ethylene copolymer and chlorinated polyethylene.
Mix at a rate of 00 parts by weight. The reason is that the plasticizer is 30
If the amount is less than 100 parts by weight, the product is poor in flexibility. Conversely, if the amount of the plasticizer is more than 100 parts by weight, the product is too flexible and the mechanical strength is lowered, and the flame resistance becomes poor. .. The amount of plasticizer depends on the properties of the plasticizer used there.
Determine the appropriate amount.

The inorganic filler is based on 100 parts by weight of a mixture of vinyl chloride-ethylene copolymer and chlorinated polyethylene.
Mix at a ratio of 10 to 150 parts by weight. The reason is that if the amount is less than 10 parts by weight of the inorganic filler, the product becomes poor in flame resistance and shape retention upon heating.
This is because if the amount is more than the weight part, the product becomes poor in flexibility.
