Description
Vynález se týká kaučukové směsi vulkanizovatelné sírou se zlepšenými užitkovými vlastnostmi, zejména směsi na bázi kaučuku izoprenového, butadien-sterénového a butadien-akrylonitrilového.The invention relates to a sulfur vulcanizable rubber composition with improved performance properties, in particular isoprene, butadiene-sterene and butadiene-acrylonitrile rubber mixtures.
Dosud jsou známé kaučukové směsi s obsahem fenolformaldehydové pryskyřice (Plastiěeskije massy No.1,str.39,1972) a těchto pryskyřic modifikovaných jinými polymery (a.o.č.24 312 z 16.5.1977, BLR).To date, rubber compositions containing phenol-formaldehyde resin (Plastieeskije massy No.1, p. 39, 1972) and these resins modified with other polymers (a.o.244 of 16.5.1977, BLR) are known.
Vulkanisáty těchto směsí máji sice lepší užitkové vlastnosti nežli vulkanisáty neobsahující uvedené pryskyřice, ale zlepšení, zejména pevnostních charakteristik, není dostatečné.Although the vulcanisates of these mixtures have better performance properties than the vulcanisates not containing said resins, the improvement, in particular the strength characteristics, is not sufficient.
Podstatou vynálezu je kaučuková směs vulkanizovatelná sírou se zlepšenými užitkovými vlastnostmi, zejména směs na bázi kaučuku izoprenového, butadien-styrenového a butadien-akrylenitrilového vyznačená tím, že obsahuje 5-5θ hmotnostních dílů fenolformaldehyd - polyvinylalkoholové pryskyřice na 100 hmot. dílů kaučuku, přičemž hmotnostní poměr pólyvinylalkoholu k fenolu v pryskyřici je od 1 : 5 do 1 : 2.The present invention provides a sulfur vulcanizable rubber composition with improved performance properties, in particular a rubber composition based on isoprene, butadiene-styrene and butadiene-acrylenitrile, characterized in that it contains 5-5% by weight of phenolformaldehyde-polyvinyl alcohol resin per 100% by weight. parts by weight of the rubber, wherein the weight ratio of polyvinyl alcohol to phenol in the resin is from 1: 5 to 1: 2.
Pokrok spočívá v tom, že vulkanisáty kaučukových směsí s obsahem fenolformaldehyd - polyvinylalkoholové pryskyřice mají podstatně vyšší pevnost v tahu, nežli vulkanisáty dosud popsaných směsi s modifikovanými a nemodifikovanými fenolfořmaldehydovými pryskyřicemi.Progress is that the vulcanisates of the rubber blends containing phenol-formaldehyde-polyvinyl alcohol resins have a significantly higher tensile strength than the vulcanisates of the blends described to date with modified and unmodified phenolphormaldehyde resins.
Nová kaučuková směs se připraví mechanickým promísením kaučuku na dvouválci nebo v hnětiči s fenolformaldehyd - polyvinylalkoholovou pryskyřicí připravenou podle čs.a.o.......A new rubber mixture is prepared by mechanically mixing the rubber on a twin-roll or in a kneader with phenol-formaldehyde-polyvinyl alcohol resin prepared according to c.a.
PV 9019-81 a dalšími přísadami různé kaučukové směsi na bázi butadien-akrylonitrilového kaučuku, které se liší druhem použité .PV 9019-81 and other additives various rubber mixtures based on butadiene-acrylonitrile rubber, which differ in the type used.
- l.a pryskyřičné příměsi : 224 770- l.and resin impurities: 224 770
Směs 1: Butadien-akrylonitrilový kaučuk (SKN-2ó) s vulkanisační v2 - * přísadou bez obsahu pryskyřičné příměsi. 224 770Mixture 1: Butadiene-acrylonitrile rubber (SKN-20) with vulcanizing in 2% resin-free additive. 224 770
Směs 2: Totéž jako ve směsi 1 s přísadou nemodifikované fenolformaldehydové pryskyřice.Mixture 2: Same as Mixture 1 with the addition of unmodified phenol formaldehyde resin.
Směs 3í Totéž jako ve směsi 1 s přísadou fenolformaldehydové pryskyřice modifikované polyamidem (alkalický PA6, Spolamid).Mixture 31 The same as in Mixture 1 with the addition of a polyamide-modified phenol-formaldehyde resin (alkaline PA6, Spolamide).
Směs 4: Totéž jako ve směsi 1 s polyvinylbutyralem (PVB).Mixture 4: Same as mixture 1 with polyvinyl butyral (PVB).
Směs 5 (předmět patentu): Totéž jako ve směsi 1 s polyvinylalkoholem (PVA).Mixture 5 (subject matter of the patent): Same as Mixture 1 with polyvinyl alcohol (PVA).

Obdobných výsledků ve zvýšení pevnosti v tahu bylo dosaženo i u butadien-styrenového a izoprenového kaučuku.Similar results in increasing the tensile strength were also achieved with butadiene-styrene and isoprene rubber.
