Abstract
Solvent-free flame-retardant enamelled wire silicone resin is disclosed. The enamelled wire silicone resin is prepared by mixing vinyl silicone oil, hydrogen-containing silicone oil, silica and a hydroxy silicone oil treating agent. A preparing method of the enamelled wire silicone resin includes 1) a step of stirring, namely a step of fully mixing the vinyl silicone oil, the silica and hydroxy silicone oil through stirring, and allowing the mixture to stand for 24 h, 2) a step of kneading, namely a step of putting the treated solvent mixture into a kneading machine and kneading, wherein kneading is performed with a cover being opened until the temperature is 175 DEG C, then the cover is covered, vacuumizing is performed, and kneading is performed under vacuum for 2 h, 3) a step of adding low-viscosity vinyl silicone oil, 4) a step of adding the solvent mixture in the step 3) to three-roll grinder and grinding for 6 h, 5) a step of adding into the kneading machine again, kneading, adding the hydrogen-containing silicone oil the weight of which is 0.6 time of the weight of the hydroxy silicone oil, opening the cover, and kneading for 3 h, and 6) a step of adding into the three-roll grinder again and grinding for 2 h. The enamelled wire silicone resin prepared through the method is good in flame retardance, good in insulativity, good in heat resistance and good in tear resistance.
Description
Technical field
The present invention relates to silicones field, especially relate to a kind of solvent-free flame-retardant type enamel-covered wire silicones.
Background technology
Silicones is the thennoset polysiloxane polymer with highly cross-linked structure.The product of early stage is via hydrolytic condensation and rearrangement by organochlorosilane (such as MeSiCl3, Me2SiCl2, MePhSiCl2, PhSiCl3, Ph2SiCl2), makes the active siloxane prepolymer of room-temperature stable.During application, it is heated further and can contract and be cross-linked into harder or that elasticity is less solid silicon resin.Silicones has the effect of good electrical insulation property, heatproof and waterproof.And weatherability is better than general organic resin.Therefore, protect in the coating on top layer in heatproof, heat-resisting and anti-wet process, be all desirable material.
Silicones molecule side base is mainly methyl, introduces phenyl and can improve thermoelasticity and cementability, improves the compatibility with organic polymer and pigment, introduces ethyl, propyl group or chain alkyl and can improve organic affinity, and improves hydrophobicity；Introduce vinyl and hydrogen-based, it is possible to use platinum catalysis additive reaction and peroxide cause cross-linking reaction；Introduce carbon official and then with more organic compound reactions, can improve cementability to base material by machine.
Existing enamel-covered wire silicones is poor due to its composition and construction features, thermostability and tear resistance.
Summary of the invention
It is an object of the invention to provide a kind of solvent-free flame-retardant type enamel-covered wire silicones, solve existing enamel-covered wire silicones thermostability and the problem of tear resistance difference.
The technical solution adopted for the present invention to solve the technical problems is: a kind of solvent-free flame-retardant type enamel-covered wire silicones, it is characterised in that: it is blended by vinyl silicone oil, containing hydrogen silicone oil, silicon dioxide and hydroxy silicon oil inorganic agent.
2, the preparation method of solvent-free flame-retardant type enamel-covered wire silicones as claimed in claim 1, it is characterised in that: comprise the following steps:
1) stirring: by ratio row stirring and evenly mixing according to mass ratio 12:6:1 of vinyl silicone oil, silicon dioxide and hydroxy silicon oil, place 24 hours；
2) mediating: the mixed solvent after step 1 processes is put into kneader and mediates, kneading to temperature of first uncapping reaches 175 °, and then cover lid evacuation is mediated 2 hours under the environment of vacuum；
3) adding low viscous vinyl silicone oil: be separately added into 20000 viscosity vinyl silicone oils of 4 times of hydroxy silicon oil weight, 5000 viscosity vinyl silicone oils of 4 times of hydroxy silicon oil weight, with 500 viscosity vinyl silicone oils of hydroxy silicon oil equivalent weight；
4) mixed solvent in step 4 is added in three roller mills and grind 6 hours；
5) it is placed again in kneader to mediate, and adds the containing hydrogen silicone oil of 0.6 times of hydroxy silicon oil weight, kneading 3 hours of uncapping；
6) it is again introduced into three roller mills to grind 2 hours.
Beneficial effects of the present invention: the solvent-free flame-retardant type enamel-covered wire silicones that this method produces has anti-flammability, good insulating, and has good thermostability and tear resistance.
Below with reference to embodiment, the present invention is described in detail.
