Abstract
The invention relates to a method for preparing liquid silicon rubber. The method comprises the following steps of: preparation of fumed silica, preparation of based glue, preparation of the liquid silicon rubber (a two-component mixing method), plate vulcanization (when in test) and the like. The method is simple and easily implemented; the prepared liquid silicon rubber has the characteristics of excellent quality and extremely high medical security or food security, and can be used as a packing for an artificial breast (breast augmentation). If the liquid silicon rubber is added into functional materials such as a conducting material, a heat conduction material, a wave guide material and the like, the liquid silicon rubber can be endowed with corresponding functions.
Description
Technical field
The present invention relates to a kind of preparation method of liquid silastic, belong to chemical technology field.
Background technology
Silicon rubber is to be base polymer (rubber) with linear organopolysiloxane, adds linking agent, reinforced filling and other Synergist S-421 95s, through cooperate, sulfuration, the elastomerics of formation.Silicon rubber is divided into melting silicone rubber and liquid silastic two big classes by its commodity form.
Liquid silastic is different with melting silicone rubber, be linear organopolysiloxane by the polymerizable medium degree be base polymer cooperate filler, various auxiliary agent and additive preparation have self-leveling or a thixotropic base-material (Compound).During use generally without large-sized processing equipment, can extrude according to kind and purposes, the notes type, apply after, vulcanization forming is an elastomerics in atmosphere or under the heating.Liquid silastic is a class organic silica gel of relative mixed milling type semi-solid state silicon rubber and common self cure single component silica gel, and this class glue has good fluidity, and sulfuration is fast, can casting can injection molding.Fluid silicone rubber is divided into selfadhesive and non-selfadhesive two big classes again.Liquid-state silicon gel can ambient cure can hot setting.Hot setting can in the several seconds, finish solidification process.
Typical liquid silastic is that soft elasticity is nonpoisonous and tasteless transparent, and medical science safety or food safety are high, can be used for artificial breast's (rich breast) filler.Functional materials such as liquid-state silicon gel adding conductive and heat-conductive guided wave then can be given its function corresponding.Other Application Areas also comprises mould manufacturing, electronic module embedding etc.
According to the difference of end-use, the preparation method of liquid silastic is also different.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of liquid silastic.
The technical scheme that the present invention takes is: a kind of preparation method of liquid silastic comprises the preparation of the preparation of gas-phase silica, basic glue, the preparation of liquid silastic (the mixing method of two components), compression molding steps such as (during tests).
Technique scheme be characterised in that following some:
1, the preparation of gas-phase silica
In planetary mixer, add M-5, add silazane again, fully stir, and be warming up to 120 ℃, vacuumize dehydration and made in about 1 hour.
2, the preparation of basic glue
In kneader, add vinyl silicone oil, open to stir, add gas-phase silica and VS silicone oil after handling again in batches, eat behind the powder, be heated to 150 ℃, vacuumize to take off and made in low two hours with the vinyl silicone oil dilution.
3, the preparation of liquid silastic
Basic glue is divided into two parts, and a catalyzer that adds makes the A component in mill, and another part adds containing hydrogen silicone oil and ethynylcyclohexanol and make the B component, promptly gets liquid silastic after the two component balanced mix.
4, compression molding
The liquid silastic that step 3 is made is pressed into certain thickness testing plate under the condition of 120 ℃ of 10min in vulcanizing press, can be used for detecting its relevant physicochemical property.
The beneficial effect of technical scheme of the present invention is embodied in: this method is simple, the liquid silastic good quality that makes, and medical science safety or food safety are high, can be used for artificial breast's (rich breast) filler.If it is added functional material such as conductive and heat-conductive guided wave then can give its function corresponding.
Embodiment
In the XSJ-200 of 200L type planetary mixer, add 10kg M-5, add the 0.8kg silazane again, open and stir, and be warming up to 120 ℃, vacuumize dehydration and made the processing gas-phase silica in about 1 hour.
In the ZH-10 of 10L type kneader, add the 1800g vinyl silicone oil, open to stir, add gas-phase silica and 167.7g VS silicone oil after 1440g handles again in batches, eat behind the powder with the dilution of 1320g vinyl silicone oil, be heated to 150 ℃, vacuumize to take off and made basic glue in low two hours.
Basic glue is divided into two parts, and a 0.3% catalyzer that adds makes the A component in the mill of XK-250 type, and another part adds containing hydrogen silicone oil and ethynylcyclohexanol and make the B component, promptly gets liquid silastic after the two component balanced mix.
The liquid silastic that step 3 is made is pressed into certain thickness testing plate under the condition of 120 ℃ of 10min in XLB type vulcanizing press, can be used for detecting its relevant physicochemical property.
The A component is not seen structurizing after half a year, the slight structurizing of B component, and visible sizing material resistive connection structure voltinism can be good.Physical performance index such as following table after the prepared liquid curing adhesive curing:
