Abstract

The invention provides a formula and a manufacturing process of flexible self-leveling epoxy material. The formula of the flexible self-leveling epoxy materials comprises a component A and a component B. The component A comprises the following components by weight: 40-60% of epoxy resin equivalent weight 190, 5-10% of reactive diluent, 0.1-0.6% of antifoaming agent, 0.1-0.3% of surface conditioning agent, 0.1-0.5% of anti-sedimentation agent, 1-6% of pigment and 30-45% of padding. The component B comprises the following components by weight: 70-80% of modified polyether amine solidification agent and 20-30 parts of end amine and polyether. The component A and the component B are mixed according to a mass ratio of 20:4-8 to manufacture the flexible self-leveling epoxy material. The flexible self-leveling epoxy material has the advantages that a manufactured terrace has good flexibility and low glass transition temperature to enable the terrace to be not easy to flake and craze on a steel platform or a refrigeration house, and anti-cracking capability at normal temperature is greatly improved.

Description

A kind of prescription of flexible epoxy self-leveling material and ME

Technical field

The invention belongs to industry ground slab construction processing technical field.

Background technology

Because of its good intensity and rigidity, epoxy resin is very success as the application of floor material, but also is restricted in many special environmental applications because of the characteristics of its rigid material.Like steel platform epoxy self-leveling floor, freezer terrace and the terrace that needs fine crack cross-over connection ability, common epoxide terrace on the steel platform very easily cracking flake and cause the terrace failure.

Summary of the invention

The present invention provides a kind of prescription and ME of flexible epoxy self-leveling material, and the prescription of said flexible epoxy self-leveling material comprises A component and B component;

Said A component, by weight percentage:

Epoxy resin equivalent 190 40-60

Reactive thinner 5--10

Skimmer 0.1-0.6

Surface conditioner 0.1-0.3

Anti-settling auxiliary agent 0.1-0.5

Pigment 1-6

Filler 30-45

Said B component, by weight percentage:

Modified polyether amine hardener 70--80

End amine and polyethers 20-30

A component and B component are processed the flexible epoxy self-leveling material after mixing by the 20:4-8 part by weight.

The ME of said flexible epoxy self-leveling material may further comprise the steps;

Handle the A component, earlier the epoxy resin that measures is poured in the clean container, slowly add thinner while stirring; Skimmer, surface adjustment auxiliary agent, pigment etc. add filler again after stirring, add anti-sedimentation agent at last; Stir after 45 minutes and detect, qualified back discharging packing;

The treatments B component is poured modified amine curing agent in the clean container into earlier, adds ending amino polyether while stirring, stirs discharging packing after 15 minutes.

Advantage of the present invention is, the terrace of processing, and flexibility that it is good and low second-order transition temperature make it in steel platform and freezer, be difficult for flaking and ftractureing, and the cracking resistance trace ability under normal temperature condition improves greatly; Reach good index:

Viscosity < 4000mpas leveling characteristics>180

Hardness>75 (sticking power of Shao-D)>3mpa

Elongation at break>< 45 ℃ of 25% second-order transition temperatures.

Embodiment

Following table is A of the present invention, the B component order by the prescription select materials, selects for use following material to process the flexible epoxy self-leveling material:

。
