Abstract
The invention discloses a silicone rubber compound for producing rubber nipples, and relates to the technical filed of rubber products. The silicone rubber compound is made of the following components in parts by weight: 80 to 100 parts of methyl vinyl silicone rubber, 1 to 10 parts of dihydroxyl polydimethylsiloxane, 10 to 50 parts of precipitated white carbon black, 0.5 to 2 parts of antioxidant, 0.5 to 1 part of methyl silicone oil, 0.5 to 2 parts of cellulose, 1 to 2 parts of modified corn starch, 3 to 5 parts of tert-butyl alcohol, 0.2 to 1 part of nano silicon carbide, 1 to 2 parts of stearic acid, and 1 to 3 parts of calcium carbonate. The silicone rubber compound has the advantages of simple components, simple preparation technology, convenient operation, and high product quality. Through adding components such as modified corn starch, tert-butyl alcohol, cellulose, and the like, the prepared rubber nipples have better using effects, and become safer and more reliable.
Description
Technical field
The present invention relates to rubber item technical field, be specifically related to melting silicone rubber and preparation method for a kind of nipple.
Background technology
Silicon rubber (English name Silicone rubber), minute heat vulcanization type (high temperature vulcanized silica gel HTV), room temperature vulcanized (RTV), wherein room temperature vulcanized is divided again polycondensation reaction type and addition reaction-type.High temperature silicon rubber is mainly for the manufacture of various silastic products, and room temperature silicon rubber is mainly to use as caking agent, Embedding Material or mould.Heat vulcanization type consumption is maximum, and heat vulcanization type divides again methyl silicone rubber, methyl vinyl silicone rubber, methyl ethylene phenyl siloxane rubber, and other also have eyeball silicon rubber, trifluoropropyl siloxane etc.In numerous synthetic rubber, silicon rubber is outstanding person therein.It has tasteless nontoxic, is not afraid of high temperature and resists the feature of severe cold, and " keeping cool ", " remaining calm " when 300 degrees Celsius and subzero 90 degrees Celsius, still do not lose original intensity and elasticity.Silicon rubber also has good electrical insulating property, oxytolerant resistance to deterioration, fast light resistance to deterioration and mildew resistance, chemical stability etc.Owing to having there are these excellent performances, make silicon rubber in modern medicine, extensively bring into play vital role.In recent years, by hospital, R&D institution and factory, jointly cooperated, trial-produceed multiple silicon rubber medical treatment product successfully.Nipple is one of articles for babies of being concerned about most of motherhood, and the quality of a nipple is about 5g, surface-area is 50～60c ㎡, and material therefor has experienced the stage of natural emulsion, natural rubber, isobutene rubber.To the quality requirements of nipple, be transparent, profile, cave shape, sense of touch and hygienic safety.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of technique simple, uses melting silicone rubber and preparation method for safe nipple.
Technical problem to be solved by this invention realizes by the following technical solutions:
A nipple melting silicone rubber, is comprised of the component of following parts by weight,
The better parts by weight of each component are:
Described methyl vinyl silicone rubber is selected methyl vinyl silicon kautschuk.
The present invention also provides the preparation method of a kind of nipple with melting silicone rubber, and its method steps is as follows,
1) first in methyl vinyl silicone rubber, add dialkyl polydimethylsiloxane, precipitated silica, mixing even in kneader;
2) then add antioxidant, methyl-silicone oil, Mierocrystalline cellulose, modified corn starch, the trimethyl carbinol, nanometer silicon carbide, stearic acid and calcium carbonate, at 130-170 ℃, heat is made into sizing material to remove volatile component and moisture in mixed 1-5 hour.
The present invention is for the preparation of baby nipple.
The invention has the beneficial effects as follows: component of the present invention is simple, and preparation technology is simple, convenient operation, the quality product of preparation is high, by adding the compositions such as modified corn starch, the trimethyl carbinol, Mierocrystalline cellulose, make the nipple result of use of preparation good, product hygienic safety is reliable.
