Abstract
The invention relates to a two-component epoxy resin adhesive and a preparation method. The two-component epoxy resin adhesive comprises a component A composed of epoxy resin, a diluents, polyamide wax and a filler as well as a component B composed of a curing agent and 2,4,6-tri(dimethylamino methyl)phenol. The two-component epoxy resin adhesive is used for anchoring (bar planting) of a building structure; can be used for anchoring of various bearing bolts with concrete and masonry, and also can be used for anchoring bolts by base material boring in building finishing work, and the two-component epoxy resin adhesive has the characteristics of good thixotropy, high strength, good storage stability without deposition and agglomeration for one year storage, and good viscosity stability.
Description
Technical field
The present invention relates to a kind of two-component epoxy resin adhesive and preparation method thereof.
Background technology
The anti-settling agent that existing double-component epoxy adhesive A component is used is commonly gas-phase silica, A component is used gas-phase silica as anti-settling agent, after often there is depositing for some time, easily there is layering caking phenomenon in product, also can there is because of the length of shelf-time ascendant trend in various degree in viscosity, serious impact the use properties of its product.
Summary of the invention
For solving the deficiency of above-mentioned tackiness agent use properties, the object of this invention is to provide a kind of stability in storage good, store and within 1 year, do not precipitate caking, epoxy adhesive product that stability of viscidity is good and preparation method thereof.
The object of the invention is to be achieved through the following technical solutions:
A component of the present invention is mixed by bisphenol A type epoxy resin, thinner, polyamide wax, stopping composition, and B component is formulated by solidifying agent, promotor;
A component raw material and weight percent are:
Bisphenol A type epoxy resin (E51) 30-50%
Thinner 3-5%
Stopping composition 40-60%
Polyamide wax 1-5%
The weight percentage sum of various raw materials is 100%;
Described thinner is butylglycidyl ether, benzyl glycidyl ether, BDDE or their mixture;
Described stopping composition is activated Calcium carbonate, active micro silicon powder or their mixture.
A method for preparing ingredients thereof is as follows:
In the high speed dispersor with register, add epoxy resin, add while stirring polyamide wax, stir and be warming up to 40-55 DEG C simultaneously, rotating speed is 1500-2000 rev/min, stirs 20-30 minute, fully, after activation, adjust rotating speed 100-200 rev/min, add thinner, stir 5-10 minute, after stirring, add stopping composition, stir 3-4 hour, stir without particulate matter, filter discharging, obtain A component.
B component raw material and weight percent are:
Solidifying agent 90-98%
2,4,6-tri-(dimethylamino methyl) phenol 2-10%
Described solidifying agent is modified phenolic amine, specifically selects: 703 solidifying agent that 810 solidifying agent that Changsha chemical institute is produced or Tianjin Yan Hai Chemical Co., Ltd. produce;
B method for preparing ingredients thereof is as follows:
At normal temperatures and pressures, respectively by solidifying agent, 2,4,6-tri-(dimethylamino methyl) phenol adds respectively in reactor, stirs 15-30 minute, after stirring, filters discharging, obtains B component.
A, B two components are mixed and can be used by weight 4-5:1.
Actual effect of the present invention is that product A component stability in storage of the present invention is good, stores and within 1 year, does not precipitate caking, and stability of viscidity is good.
Embodiment
example 1in the high speed dispersor with register, add 30kg epoxy resin, add while stirring 3kg polyamide wax, stir and be warming up to 40-45 DEG C simultaneously, rotating speed is 1500 revs/min, stirs 25 minutes, fully, after activation, adjust 120 revs/min of rotating speeds, add 3kg benzyl glycidyl ether, stir 5 minutes, after stirring, add 56kg activated Calcium carbonate, stir 3 hours, stir without particulate matter, filter discharging, obtain A component;
At normal temperatures and pressures, respectively by 98kg810 solidifying agent, 2kg2,4,6-tri-(dimethylamino methyl) phenol adds respectively in reactor, stirs 20 minutes, after stirring, filters discharging, obtains B component;
?the baking box that A component is placed in to 40 DEG C toasts, and within 1 year, does not occur precipitation caking phenomenon, and it is 85000mPa.S that viscosity does not toast front test, and when baking, because it volatilizees on a small quantity, after baking, test viscosity is 85500mPa.S, and viscosity changes little, and stability of viscidity is good.
example 2in the high speed dispersor with register, add 45kg epoxy resin, add while stirring 4kg polyamide wax, stir and be warming up to 45-55 DEG C simultaneously, rotating speed is 2000 revs/min, stirs 20-25 minute, fully, after activation, adjust 200 revs/min of rotating speeds, add 3kg butylglycidyl ether, stir 8 minutes, after stirring, add 45kg active micro silicon powder, stir 3.5 hours, stir without particulate matter, filter discharging, obtain A component;
?at normal temperatures and pressures, respectively by 95kg703 solidifying agent, 5kg2,4,6-tri-(dimethylamino methyl) phenol adds respectively in reactor, stirs 25 minutes, after stirring, filters discharging, obtains B component;
the baking box that A component is placed in to 40 DEG C toasts, and within 1 year, does not occur precipitation caking phenomenon, and it is 92000mPa.S that viscosity does not toast front test, and when baking, because it volatilizees on a small quantity, after baking, test viscosity is 92300mPa.S, and viscosity changes little, and stability of viscidity is good.
reference examplesby above A component formula, change polyamide wax into gas-phase silica, other proportioning, material are all constant, and after preparing, the baking box that A component is placed in to 40 DEG C toasts, within 6 months, just there is precipitation caking phenomenon, it is 86000mPa.S that viscosity does not toast front test, and when baking, because it volatilizees on a small quantity, toasting and testing viscosity after 6 months is 150000mPa.S, viscosity changes greatly, and stability of viscidity is poor.
