JPS59179635A - Production of inorganic substance-filled polyolefin resin foam - Google Patents

Abstract

PURPOSE:To obtain a foam which is filled with a filler in a high filling ratio but yet has a high quality, by further adding a surfactant to a polyolefin resin composition containing an inorganic substance, a blowing agent, and an organic peroxide, and foaming the produced mixture by heating. CONSTITUTION:A composition is formed by mixing (A) 100pts.wt. resin composition prepared by mixing 100pts.wt. polyolefin resin (e.g., polyethylene or polybutadiene) with about 30-250pts.wt. inorganic compound powder (e.g., aluminum hydroxide of an average particle diameter of about 0.01-50mu), about 5- 50pts.wt. heat-decomposable blowing agent (e.g., azodicarbonamide), and an organic peroxide (e.g., di-t-butyl peroxide) with (B) 0.05-10pts.wt. surfactant (preferably, a surfactant of a fluorine- or silicone-type). The produced composition is molded at a temperature lower than the decomposition temperature of the blowing agent, and the molding is heated to obtain a foam.

Description

[Detailed Description of the Invention] Is there an inorganic substance in the concentration of the present invention? The present invention relates to a method for producing a polyolein resin foam containing the present invention.

Addition of mineralized additives to polyoleain resin is carried out for the purpose of making it non-polluting, flame retardant, and of poor quality.For example, A 71 (O)i) s s M g (OH)
*It is possible to avoid flame-retardant gas by exfoliating the ayu crystal water vomit at a fixed temperature in a water bottle such as the above, and it emits noxious gas when burned compared to so-called halogen fibrils. Katana et al. have been attracting attention because they have no occurrence of female value.

However, the original polyoleain resin molded product r
It is difficult to obtain a foamed material when heated under normal pressure with zero force, and Samurai et al.
Even if Marugame were to be used, it would be coarse and rough on the surface, requiring a large amount of foaming agent to obtain a high foaming agent, resulting in an inorganic polyolefin yarn-side foaming material. In order to do this, a cross-linked structure 4 is introduced under pressure to decompose the aging agent, and then there is a method of thermal expansion under pressure, but continuous production is difficult and production efficiency is reduced because it is produced in the nokutsuchi process. death,
However, since it tends to be too presumptuous and it is impossible to manufacture long foam products, its uses tend to be limited.
The purpose of this product is to improve the productivity of polyolefin resin based on the concentration of inorganic crystals, the expansion ratio of the foam, and the production of a smooth and beautiful machined body with a smooth and beautiful foam. Industrially available for continuous menstruation :) We provide all 5 methods.

In carrying out the present invention, the functions of ascending, returning, and off-setting operations are essential. It is not clear about the mechanism of the action of the old-fashioned interlayer used in the present invention. I think it's because she's pregnant. :) When practicing, the 2V water is uniform to avoid old people, and the bubble diameter becomes small due to the gas pressure inside the bubble. , 4 bite the membrane
iJ + ffi depends on Qi en package ti'', and Kas is reduced from the small 10,000 people to the 3000 million people, and finally, it is unified to the large 10,000. I hear it. Therefore, since the pressure difference between the bubbles has a value of V compared to the surface tension, just like a blunt agent, reducing the force on the surface of the bubbles prevents the formation of bubbles. This yields a 1+114'lJ-sized milled body with large bubbles. Since reeds are difficult to block air intake, there is a slight illusion of a bubble film.
It becomes n.

Since there is less gas escaping, it is thought that it is possible to reduce the amount of Himekase in the city.

The activators used in the present invention include alkylphenol type and nrubitan ester 2!

A sheet of O was placed in a 250"C reoven and foamed. The results are shown in Ayurai Zen6-4. Table 4 shows that the foaming density of the foam with surfactant added was small and the bubbles were fine and smooth. However, in Comparative Example 4, in which no surfactant was added, the foaming was incomplete and the surface smoothness was poor.
