Abstract
The invention discloses a production recipe and a preparation method of novel halogen-free flame retardant epoxy resin sealing glue. The glue comprises glue A and glue B, wherein the glue A comprises the following ingredients including low-viscosity epoxy resin, acetone, aluminium hydroxide, magnesium hydrate and ammonium polyphosphate, and the glue B comprises the following ingredient including low-molecular-weight polyamide resin and acetone. The glue has the advantages that the halogen-free flame retardance is realized, the environment is protected, the production cost is low, the bonding intensity is high, the sealing effect is good, and the glue is widely applied to the encapsulation of electric appliance devices and the bonding of the same kind of materials or different kinds of materials such as iron, steel, aluminum, stainless steel, ABS, PVC, polycarbonate, organic glass, polyurethane, polystyrene, fiber glass reinforced plastics, ceramics, cement, stone, bakelite, wood and the like. The glue can also be used for the restoration of parts of automobiles, motorcycles, tractors and various machines, the bonding assembly of various products, the gluing of nameplates, signboards, identifications and decoration ornaments, various kinds of emergency and emergency repair of the production sites and the fields, and the repair of articles for daily use.
Description
Technical field
The invention belongs to chemical technology field, relate to production formula of a kind of novel halogen-free flame-retardant epoxy resin sealant and preparation method thereof.
Background technology
At present, epoxy resin sealant on the market exists not environmental protection and the glue problem that impact uses that takes on a red color, contain the requirement that a large amount of halogen flames does not reach environmental protection in some epoxy sealing glues, also have in some epoxy sealing glues and contain red phosphorus combustion inhibitor, so that colloid takes on a red color, thereby affected the use of glue, therefore need a kind of novel halogen-free flame-retardant epoxy resin sealant of development.
Summary of the invention
The purpose of this invention is to provide production formula of a kind of novel halogen-free flame-retardant epoxy resin sealant and preparation method thereof.
In order to achieve the above object, a kind of novel halogen-free flame-retardant epoxy resin sealant of the present invention is a kind of pair of component cement, formed by A glue and B glue, the composition of its A glue is: low viscosity epoxy resin, acetone, aluminium hydroxide, magnesium hydroxide and ammonium polyphosphate, the weight percent that its prescription forms is: low viscosity epoxy resin 30%～50%, acetone 30%～50%, aluminium hydroxide 5%～10%, magnesium hydroxide 5%～10%, ammonium polyphosphate 5%～10%, and each component concentration sum is 100% in the prescription; The composition of B glue is: low-molecular-weight polyamide resin, acetone, and weight percent that its prescription forms is: low-molecular-weight polyamide resin, 50%～70%, acetone 30%～50%, each component concentration sum is 100% in the prescription.
The specification of low viscosity epoxy resin is WSR-615 in the above-mentioned prescription, and the specification of low-molecular-weight polyamide resin is 650, and the granularity of aluminium hydroxide and magnesium hydroxide is 1500 orders, and the mean polymerisation degree of ammonium polyphosphate is 1000.
The specific embodiment of the present invention is:
1, the preparation of A glue:
According to formulation ratio, acetone is added in the low viscosity epoxy resin, stir with stainless steel bar, make the low viscosity epoxy resin dissolving be the glue of thin shape, then in glue, add aluminium hydroxide, magnesium hydroxide and ammonium polyphosphate successively, continue to stir with stainless steel bar, until stir.
2, the preparation of B glue:
Press formulation ratio, acetone is added in the low-molecular-weight polyamide resin, stir with stainless steel bar, make it become evenly thick liquid.
3, using method:
Get each 1 part in A glue and B glue during use, to can use after its mixing and stirring, lower about 8 minutes primary solidification location of normal temperature finger pressure, reach maximum intensity after just can reaching 70%, 24 hour of final strength after 1 hour, this glue can use in-60 ℃～+ 120 ℃ scopes, if the surface treatment of adherend spare is abundant, A, B component measure accurately in proportion, mix, and then adhesive effect is best.
The invention has the beneficial effects as follows, this glue halogen-free flameproof, environmental protection, production cost is low, and bonding strength is high, good sealing effect.This glue is widely used in the embedding of appliance component, is used for the bonding of the of the same race or foreign material such as iron, steel, aluminium, stainless steel, ABS, PVC, polycarbonate, synthetic glass, urethane, polystyrene, glass reinforced plastic, carbon fibre reinforcement, pottery, cement, stone material, bakelite, timber.This glue can also be used for the reparation of automobile, motorcycle, tractor and various element parts, be used for the bonding assembling of various products, the repairing of the stickup of nameplate, signboard, sign, decoration jewelry and production scene and open-air various emergency first-aid repair and leak stopping and articles for daily use.
