Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a stabilized halogen-containing resin composition, specifically, a halogen-containing resin composition by adding a lead-based stabilizer, an organotin carboxylate, and a specific piperidine compound. The present invention relates to a halogen-containing resin composition that is prevented from occurring and has improved physical properties.

In general, halogen-containing resins have poor stability against heat and light, and are prone to thermal decomposition mainly due to dehydrohalogenation during hot molding, resulting in decreased mechanical properties and poor color tone of processed products. This can lead to serious disadvantages.

In order to avoid such drawbacks, it has been conventional practice to add one or more kinds of stabilizers for stabilization.

Among these stabilizers, lead-based stabilizers are widely used because they have a relatively large thermal stabilizing effect.

However, halogen-containing resins to which lead-based stabilizers have been added have drawbacks, such as coloring during processing, insufficient light resistance, and the phenomenon of chalking, especially when used outdoors. That was what was requested.

Furthermore, in recent years, even higher thermal stability under severe temperature conditions has been required.

In order to meet these demands, lead-based stabilizers and organotin compounds have been used in combination, but this has had little effect on preventing chalking and has been insufficient in terms of thermal stability. It has also been proposed to use a 2,6-dimethyl-1,4-dihydropyridine compound in combination with a lead-based stabilizer to prevent chalking, but the effect is still insufficient and further improvements are desired. It had been.

As a result of intensive studies in view of the above-mentioned current situation, the present inventors have discovered that, in addition to a system that uses a lead-based stabilizer and an organic tin carboxylate, at least one type of 2,2",6,6-titramethylpiperidine-based compound is added to the system. It has been found that when added in combination, a halogen-containing resin composition can be obtained which prevents chalking, significantly improves thermal stability, thermal colorability, and initial colorability, and also significantly improves mechanical properties.

The present invention was made based on the above findings, and consists of adding 0.1 to 10 parts of fal lead stabilizer to 100 parts by weight of halogen-containing resin.
parts by weight, 0.01 to 5 parts by weight of (bl organotin carboxylate) and (C) 0.001 to 3 parts by weight of at least one compound having a 2,2,6.6-titramethylpiveridyl group. The present invention provides a halogen-containing resin composition.

Hereinafter, the halogen-containing resin composition of the present invention will be explained in detail.

Examples of lead-based stabilizers used in the present invention include white lead, basic lead silicate, basic lead sulfate, dibasic lead sulfate, tribasic lead sulfate, basic lead sulfite, and dibasic phosphorous acid. Lead, silica gel co-precipitated lead silicate, dibasic lead phthalate, tribasic lead maleate, lead salicylate, lead stearate, basic lead stearate, dibasic lead stearate, lead laurate, lead octylate, Examples include lead 12-hydroxystearate, lead behenate, lead naphthenate, and the like.

The amount of the lead-based stabilizer added is 0 per 100 parts by weight of the resin.
．． The amount is 1 to 10 parts by weight, preferably 0.5 to 5 parts by weight.

The organotin carboxylate used in the present invention includes:
aliphatic-valent carboxylates such as octoate, laurate, myristate, palmitate, stearate, isostearate of mono- or dimethyltin, mono- or dibutyltin, mono- or dioctyltin or mono- or bis(butoxycarbonylethyl)tin; Maleate polymers, butyl maleate, benzyl maleate, oleyl maleate, stearyl maleate, and other malates; and mixed salts or basic salts thereof are included, but maleates are particularly effective (preferable).

The amount of the organic tin carboxylate added is 0.01 to 5 parts by weight, preferably 0.05 to 5 parts by weight, per 100 parts by weight of the resin.
It is 3 parts by weight.

Furthermore, many compounds having a 2,2,6,6-titramethylpiperidyl group are known to be used in the present invention, and for example, compounds described in the following patent publications may be used. I can do it.
