Abstract
The invention discloses a food-contacting silicone rubber compound, and relates to the technical field of rubber products. The silicone rubber compound is composed of the following components in parts by weight: 80 to 100 parts of methyl vinyl silicone rubber, 10 to 50 parts of white carbon black, 1 to 10 parts of dihydroxyl polydimethylsiloxane, 5 to 15 parts of titanium dioxide, 1 to 2 parts of peanut oil, 2 to 4 parts of polyethylene fiber, 1 to 3 parts of plant gum, 1 to 3 parts of silicon micropowder, 5 to 10 parts of natural rubber, 2 to 4 parts of resin emulsion, and 0.5 to 1 part of crosslinking agent. The components of the compound are simple, moreover, components such as polyethylene fiber, plant gum, and resin emulsion are added, and thus the prepared products are safe and reliable. The products made of the compound cannot be colored when contacting edible oil, flavoring powder, curry powder, coffee, and the like, and thus have high cleanness and safeness.
Description
Technical field
The present invention relates to rubber item technical field, be specifically related to a kind of melting silicone rubber and preparation method that can contact food.
Background technology
Silicon rubber (English name Silicone rubber), point 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 maximum, 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 " in the time of 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.The resistance to elevated temperatures of silicon rubber makes its parts that are often used to various class contact food containers as suction pipe of press heater packing ring, food flavouring and beverage etc. to the security of human body in time.Its hygienic standard is substantially identical with melting silicone rubber with nipple; But not painted while requiring increase stain resistance to contact edible oil, flavour powder, curry powder, coffee, increase clean feel and the sense of security.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of physics, chemical property are good, preparation simply can contact food melting silicone rubber and preparation method.
Technical problem to be solved by this invention realizes by the following technical solutions:
Melting silicone rubber that can contact food, is made up of the component of following parts by weight,
The optimum weight umber of each component is,
Described white carbon black is that surface-area is 200m
2the thermal silica of/g.
Described dialkyl polydimethylsiloxane is that viscosity is a of 30mPa.s, w-dialkyl polydimethylsiloxane.
The median size of described titanium dioxide is 0.15um.
The present invention also provides a kind of preparation method of melting silicone rubber that can contact food, and its method steps is as follows,
A. in methyl vinyl silicone rubber, add white carbon black, dialkyl polydimethylsiloxane, mixing even in kneader, at 150-180 DEG C, mixed 1 hour of heat, is made into sizing material;
B. in sizing material, adding median size is the titanium dioxide of 0.15um in rubber unvulcanizate machine mixing 30 minutes, then add peanut oil, polyethylene fibre, vegetable jelly, silicon powder, natural rubber, resin emulsion and linking agent mixing evenly, mixed 2 hours of heat at 150-180 DEG C.
The invention has the beneficial effects as follows: component of the present invention is simple, increase the compositions such as polyethylene fibre, vegetable jelly, resin emulsion, make goods safe and reliable, not painted when contact edible oil, flavour powder, curry powder, coffee etc., clean feel and the sense of security are higher.
