Abstract

PURPOSE:The titled composition which can be vulcanized after film formation, prepared by adding a metal oxide to a specified sulfohalogenated polyolefin latex. CONSTITUTION:An organic solvent solution of 100pts.wt. sulfohalogenated polyolefin (e.g., sulfochlorinated polyethylene) is dispersed in water in the presence of 0.1-20pts.wt. emulsifier (e.g., polyoxyethylene alkylphenyl ether sulfate ester salt), and the organic solvent is distilled off to obtain a sulfohalogenated polyolefin latex. This latex is mixed with an aqueous solution of 0.01-10pts.wt., per 100pts.wt. sulfohalogenated polyolefin, metal oxide (e.g., ZnO) and 0.01- 5pts.wt. vulcanization accelerator (e.g., tetramethylthiuram monosulfide) and the mixture is aged with stirring for about 24hr, cast on a support, and dried at 60 deg.C or above. The obtained film is vulcanized at 70-250 deg.C for several-about 30min.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sulfohalogenated polyolefin latex composition and a process for recursive addition obtained from the sulfohalogenated polyolefin latex.

Sulfohalogenated polyolefins (hereinafter referred to as sHP and C), commercially available sulfochlorinated polyethylenes, are weather resistant;

Taking advantage of the excellent properties of yuzu such as good flame resistance, yuzu is used for various purposes such as yuzuki hoses, liners, liners, paint, and escalator handles. In some cases, StiP is mixed with sHPv raw rubber, but in other cases, StiP is treated using methods such as dipping, coating, and spraying. When used for one period in the state of a class melting solvent,

Although there is no need to worry about sulfurization, there is little known about the 8 and 4F latex J11 latex. There is no known method of vulcanizing f& films.

The present inventors conducted vulcanization of StfP latex in two C
As a result of tt・r, the solvent bath solution of St(P) was dispersed in the emulsifier-presence bottle, and i'i eat J
By distilling off the tF latex and adding a specific vulcanizing agent to the P latex, a film is formed.
We have found a method for producing a C S M P latex composition and fJn obtained from the latex.

The Si(P latex composition of the present invention is prepared by dispersing an organic Pocari solution of sitP in water containing an emulsifier and then distilling off the organic solvent.) It is a composition in which a small amount of metal oxide is added to the agent and L, if necessary, an aqueous dispersion of a vulcanization accelerator is added, and the liquid composition is mixed and aged, and dried at a temperature of 60°C or higher to form a film. This is a coating method in which 9q ridges are heated and then heated.

Latexization of SHk' is generally performed using polyoxyethylenenon rubitan monolaurate, polyoxyethylene sorbitano monooleate, dodecylphenyl polyglycol ether as the organic material of SIP.

Polyoxyethylene alkylene ether (potassium or ammonium) is a polyoxyethylene alkylene ether diacetate ester, and these can be used alone or in combination.

The number of moles of No added to 11 constituting the polyethylene oxide is usually conveniently 1 to 99, but preferably 8 to 5.
If a compound with 0 mole addition is used, a slag is often obtained.

Subject: 17J It cannot be said to be advantageous as it may have an adverse effect on the character.

The metal oxides used in the invention are positional oxides such as red sea bream oxide, zinc oxide, and -lead oxide, and these can be used alone or in a mixture of 24 U or more. The toilet touch is 814P100 weight in latex, 0. 1) Weight is preferably 0.1 to 5 parts by weight, more preferably 0.1 to 2 parts by weight.

If the amount of acid used is more than this, it will become difficult to form a SHP and the original characteristics of SHP will be affected, which is not desirable.
From this point on, it is difficult to perform optical vulcanization with a small amount of F.

When performing vulcanization, a vulcanization accelerator is usually used in combination, but it is also preferable to use it in combination in the case of 5itp latex.
