Abstract
The invention belongs to the technical field of sealants, and in particular relates to an inflaming retarding sealant based on a modified polyether polymer and a preparation method thereof. The inflaming retarding sealant is prepared from the following raw materials in parts by weight: 10-35 parts of modified polyether, 5-15 parts of fire retardant, 12-50 parts of plasticizer, 15-40 parts of inorganic filling material, 0.01-0.3 part of catalyst and 0.14-0.5 part of antioxidant. The preparation method is simple and practicable and is easy to implement. The modified sealant provided by the invention has no solvent, good flexibility, good cohesive property with glass, aluminum products and marble inorganic materials ultraviolet light resistance, and burning oxygen index of more than 21%.
Description
Technical field
The invention belongs to the sealer technical field, be specifically related to a kind of flame retardant sealant based on the modified polyether polymkeric substance and preparation method thereof.
Background technology
Sealer is with the on-the-spot pointing seam of indefinite form, bonding interface and bears the sealing material of seam displacement deformation.It generally is the paste material, after the curing base material is connected into an integral body.Early stage sealer is a base-material by the dope of dryness (or non-dryness) such as pitch, tar, natural (or synthetic) resin, natural (or synthetic) rubber, cooperates certain auxiliary agent to form.High performance sealant has 3 kinds at present: the sulphur of birdsing of the same feather flock together, silicone and urethane.
Based on flame retardant sealant of modified polyether polymkeric substance and preparation method thereof is a kind of new modified sealer.The seventies and eighties in 20th century is at first by Japanese Development and Production.The main chain of this base polymer is a polyethers, and has hydrolyzable silane end group, therefore has the advantage of silicone sealant and polyurethane sealant concurrently.The prescription of silicon-modified polyether sealing agent is to be major constituent with the silicon-modified polyether resin, is equipped with that curing catalysts, reinforcing filler and various property-modifying additive constitute.Also need add property-modifying additives such as softening agent, coupling agent, promotor, pigment, stablizer, thixotropic agent as required.Yet mentioned component all is inflammable component, and the burns oxygen index is low, and point of ignition is low, discharges toxic gas during burning.
Summary of the invention
The purpose of this invention is to provide a kind of flame retardant sealant based on the modified polyether polymkeric substance, have solvent-free, snappiness good, and is good with glass, aluminium, marble class inorganic materials cohesiveness, ultraviolet light, good stability and have from fiery self-gravitation performance; The present invention provides its preparation method simultaneously.
Flame retardant sealant based on the modified polyether polymkeric substance of the present invention, process by the raw material of following mass fraction:
Described modified polyether is silane-modified ternary polyoxygenated third rare ether of molecular-weight average 4500～6000 or 6000～8000.
Described fire retardant agent is eight bromo ether, triphenylphosphate, TDE, decabromodiphynly oxide or zinc borate.
Described softening agent is a Witcizer 300.
Described mineral filler is a Shawinigan black.
Described catalyzer is a stannous octoate.
Described oxidation inhibitor is DBPC 2,6 ditertiary butyl p cresol.
The preparation method of described flame retardant sealant based on the modified polyether polymkeric substance comprises the steps:
(1) takes by weighing each raw material by formula ratio;
(2) modified polyether is joined in the reaction kettle, slowly be warming up to 180～200 ℃, vacuum outgas 1～2 hour is cooled to 60～80 ℃;
(3) add softening agent, mineral filler, oxidation inhibitor, catalyzer and fire retardant, 80～100 ℃ of following vacuum stirring 1～2 hour;
(4) be cooled to 30～40 ℃, inflated with nitrogen is processed after removing vacuum.
The vacuum tightness of the vacuum tightness degassing and vacuum stirring keeps 0.1MPa ± 0.02Mpa, and nitrogen pressure does not limit in the step (4), mainly is in order to remove vacuum.
Beneficial effect of the present invention is following:
That modified polyether seal glue of the present invention has is solvent-free, snappiness good,, ultraviolet light good with glass, aluminium, marble class inorganic materials cohesiveness, burns oxygen index are higher than 21%, and its preparation method is simple, and is easy to implement.
