Abstract
The invention discloses a kind of epoxy resin-nitrile rubber adhesive and its preparation method, the product belongs to chemical building material field, producing the raw material that the product uses includes: liquid-state epoxy resin 28%-30%, nitrile rubber 12-14%, styrene 47%, polyamide 4%, vitreous silica silicon powder 3%, mica powder 2%, talcum powder 2%, by blending at different temperatures come finished product, product is a kind of universal adhesive, it is liquid-state epoxy resin and prepared by nitrile rubber is dissolved in solvent, with adhesive strength height, durability is good, glue-line is flexible, impact resistance and vibration, there is preferable oil resistant, it is water-fast, it is alkaline-resisting, the adhesive of acid resistance, there is preferable bonding effect to multiple material.
Description
Technical field:
Product of the present invention belongs to chemical building material field more particularly to a kind of epoxy resin-nitrile rubber adhesive and its preparation side
Method.
Background technique:
Epoxy resin refers to the organic high molecular compound in molecule containing two or more epoxy groups, epoxy resin tool
There is good physical and chemical performance, it has excellent adhesive strength to the surface of metal and nonmetallic materials, and dielectric properties are good
Good, set shrinking percentage is small, and hardness is high, and flexibility is preferable, to alkali and most of solvent-stable, thus is widely used in production bonding
Agent；Since single epoxy resin impact resistance lesion capability is poor, poor toughness, heat resistance are relatively low, it is some special to be difficult to adapt to
Occasion, thus epoxy resin is compounded, the adaptability of Lai Tigao epoxyn.Product of the present invention be exactly
Nitrile rubber is added in epoxy resin and other materials, the advantage for keeping its original play, and damages such as impact resistance of its disadvantage
Hurt that poor ability, poor toughness, heat resistance are low, insulation performance is poor is overcome, becomes the more excellent adhesive of performance, butyronitrile
Rubber has excellent oil resistivity, resistance to ag(e)ing, also has good water resistance, air-tightness and excellent adhesive property and ring
The advantages of making two kinds of materials after oxygen resin compounding, is superimposed.
Summary of the invention:
Present invention mainly solves the problem of be to provide a kind of epoxy resin-nitrile rubber adhesive and preparation method thereof, production should
The raw material that product uses includes: liquid-state epoxy resin 28%-30%, nitrile rubber 12-14%, styrene 47%, polyamide 4%, melting
Quartzy silicon powder 3%, mica powder 2%, talcum powder 2%.
The present invention can be achieved through the following technical solutions:
(1) styrene of formula ratio is first added in chemical reaction kettle, is warming up to 48-50 DEG C, starts blender stirring, then delays
The liquid-state epoxy resin and nitrile rubber of slow addition formula ratio, are stirred 1.0-1.2 hours after mixing.
(2) it is cooled to room temperature, continues to stir, while stirring by the polyamide of formula ratio, vitreous silica silicon powder, mica
Powder, talcum powder are sent into chemical reaction kettle, obtain finished product after being stirred to react 0.3-0.4 hours.
Preferably, the purity of the liquid-state epoxy resin is 55%.
Preferably, the purity of the nitrile rubber is 80%.
The beneficial effects of the present invention are: product is a kind of universal adhesive, it is that liquid-state epoxy resin and nitrile rubber are molten
Prepared by solvent, have that adhesive strength is high, durability is good, glue-line is flexible, impact resistance and vibration, have preferable oil resistant,
Water-fast, alkaline-resisting, acid resistance adhesive has preferable bonding effect to multiple material.

Liquid-state epoxy resin and account for total amount be 13% nitrile rubber, stirred 1.1 hours after mixing；It is cooled to room temperature, continues to stir,
Polyamide that total amount is 4% will be accounted for while stirring, is accounted for vitreous silica silicon powder that total amount is 3%, is accounted for mica powder that total amount is 2%, accounts for
The talcum powder that total amount is 2% is sent into chemical reaction kettle, obtains finished product after being stirred to react 0.35 hour.
Embodiment 3:
Styrene of the total amount for 47% will be accounted for, is warming up to 50 DEG C, starts blender stirring, being then slowly added and accounting for total amount is 30%
Liquid-state epoxy resin and account for total amount be 12% nitrile rubber, stirred 1.0 hours after mixing；It is cooled to room temperature, continues to stir,
Polyamide that total amount is 4% will be accounted for while stirring, is accounted for vitreous silica silicon powder that total amount is 3%, is accounted for mica powder that total amount is 2%, accounts for
The talcum powder that total amount is 2% is sent into chemical reaction kettle, obtains finished product after being stirred to react 0.4 hour.
