Abstract
The invention discloses a single-component room temperature solidified organic silicone adhesive. The adhesive is in a single-component mode. According to the formula, the adhesive comprises, by mass, 30-40% of specific-viscosity 107 silicon rubber, 10-20% of plasticizers, 10-20% of reinforcement fillers, 5-10% of catalysts, 10-20% of cross-linking agents, 10-18% of curing agents and 1-5% of dyeing fillers. Elastomer can be kept within a wide temperature range, and the single-component room temperature solidified organic silicone adhesive is good in power of bonding various substrates and has excellent high temperature resistance, low temperature resistance, weather resistance and medium resistance.
Description
Technical field
The present invention relates to a kind of preparation of single-component room-temperature vulcanized organosilicon sizing agent, belong to chemical field.
Background technology
Structure due to organosilicon uniqueness has excellent weathering resistance, weather resistance, resistant of high or low temperature, hydrophobicity, ultra-violet radiation resisting and elasticity cementing ability, even if still good physicals can be kept in the environment for use of harshness, thus the fields such as building, electronic apparatus, automobile, new forms of energy and the consumer's goods that are widely used in are as sealing agent, and the performance section of its brilliance counteracts fancy price.The surface tension that organosilicon is low makes it become again excellent release material.In the fields such as food, packaging, building, automobile, electronics, moulded product, widely use organic silicon adhesive, become indispensable novel high polymer material in national defence and national economy.But there is the shortcomings such as hardness is low, flame resistivity is poor, price is higher in organosilicon simultaneously.Along with the raising that every profession and trade requires production efficiency and constant product quality, higher requirement be it is also proposed to the performance of organosilicon sealant.Therefore, the organosilicon sealant working out a kind of high-adhesion energy is necessary.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of fast setting, had high-adhesive-strength to PC material, at room temperature-vulcanized organic silicon adhesive.
The technical solution realizing the object of the invention is: a kind of monocomponent room-temperature cured organic silicon type tackiness agent, this tackiness agent is single component, be calculated in mass percent, formula comprises following component and proportioning: particular viscosity 107 silicon rubber of 30%-40% massfraction, the softening agent of 10%-20% massfraction, the reinforced filling of 10%-20% massfraction, the catalyzer of 5%-10% massfraction, the linking agent of 10%-20% massfraction, the solidifying agent of 10%-18% massfraction, the dyeing filler of 1%-5% massfraction.
Wherein, body material is mainly hydroxy-end capped linear poly-diorganosiloxane class, and softening agent is dioctyl phthalate (DOP), Bisphthalate, epoxy plasticiser, one or more of polypropylene glycol monobutyl ether.γ-aminopropyltrimethoxysilane selected by solidifying agent, N-phenyl-γ-aminopropyltrimethoxysilane, one or more in γ-ureido-propyl Trimethoxy silane; Polysilicon acid fat selected by linking agent, ring-type or wire oligosiloxane, polyhydroxy siloxane, oligosiloxane, acyloxy silane, organoalkoxysilane, isopropyl alkene oxosilane, one or more of aminosilane.Reinforced filling selects light calcium carbonate, aerosil, white carbon black, one or more of gas phase titanium dioxide.Catalyzer has selected organotin carboxylate's thing and organic chelate, the inner complex of titanic acid ester and titanium, the one of amine and platinic compound or mixture.
The beneficial effect that technical solution of the present invention is brought:
Single-component room-temperature vulcanized organo-silicone rubber is one of main products of condensed type liquid silastic, and just can meet moisture at normal temperatures and pressures just sulfuration can become elastomerics, and it is convenient especially to use.During sulfuration, not heat release, does not absorb heat, and the sulfuration body of transparent and color arbitrarily can be obtained, its viscosity and denseness seldom by the impact of temperature, can keep elastomerics in very wide temperature range, good to various base material cohesive force, with excellent high-low temperature resistant, weathering resistance and resistance to medium.
