Description
Technical field
The present invention relates to the production methods of Halogen high-performance refractory silicone sealant, and in particular to a kind of one-component Halogen is high
The production method of performance flame-proof silicone sealant.
Background technology
Building fire has the characteristics that sprawling is fast, evacuating personnel is difficult, difficulty of putting out a fire to save life and property is big, especially skyscraper, once
Fire occurs, loss is often very heavy.The fire protecting performance of building is improved, it not only will be from raising outer wall material particularly exterior wall
The fire protecting performance of thermal insulation material considers, also to put forth effort to improve the anti-flammability of the silicone sealant of building joint sealing.With generation
The raising that various countries of boundary require building fire protection rank and the concern to curtain wall fire protecting performance, the flame retardant property of silicone sealant are modified
Also become focus of attention in industry.All it is by adding in fire retardant in formula because silicone adhesive itself does not have flame retardant type
Method realize the flame retardant effect of silicone adhesive.The fire retardant being widely adopted at present mainly has halogenated flame retardant, inorganic fire-retarded
Synergistic fire retardant that agent, a variety of fire retardants are used in mixed way etc..Halogenated flame retardant flame retardant effect is good, but because halogen system is fire-retardant
Smoke amount is big when agent is burnt, and discharges toxic, pollution gas, is unfavorable for health and environmental protection.Inorganic combustion inhibitor is mainly hydrogen-oxygen
Change aluminium, magnesium hydroxide and metal oxide, this based flame retardant has the function of fire-retardant, smoke elimination, filling etc., and flue gas in combustion process
It is less.But since the additive amount of inorganic combustion inhibitor is big, the mechanical property for be easy to causeing silicone adhesive is affected, easily so that glue
Body embrittlement is hardened, so as to which the resist displacement ability of silicone adhesive be caused to decline.The present invention exists for halogen containing flame-retardant and inorganic combustion inhibitor
Major drawbacks present in silicone adhesive application, provide a kind of production method of Halogen high-performance refractory silicone sealant.The hair
It is bright using the aluminium hydroxide that surface modification treatment is crossed as fire retardant, controlled by the selection of crosslinking agent and dosage, not only ensured
The feature of environmental protection of silicone adhesive burning, while make the mechanical property of silicone adhesive and the displacement capacity unaffected again, it is ensured that silicone adhesive
The applicability of building fire protection function.
Invention content
The purpose of the present invention is in view of the above shortcomings of the prior art, provide a kind of Halogen high-performance refractory silicone seal
The production method of glue, solve halogen system flame-proof silicone sealant not environmentally makes silicone adhesive power with common inorganic flame-proof silicone sealant
Learn the main problem of performance impairment.The invention is strong with environmental protection, low cigarette, flame retardant property protrusion, colloid high resiliency, resist displacement ability
The advantages that, it is ensured that the applicability of silicone adhesive building fire protection function.
The present invention can be achieved by the following measures：
