Problems solved by technology

[0009] In the above methods, in the process of DCH to ECH, in order to avoid the hydrolysis of DCH, in the process of dead cycle refining, low concentration of weak base must be used, so the water consumption is quite large, and the energy consumption is also large, so the waste water and carbon dioxide The amount of discharge is very large, causing serious environmental load, which does not meet the requirements of environmental protection

Embodiment 1

[0042] In the first step, weigh 100 parts of environmentally friendly bisphenol A epoxy resin, 90 parts of titanium dioxide, 2.0 parts of fumed silica and 30 parts of xylene, and grind and disperse at high speed with a ball mill for 3 hours, then add 2.6 parts of polyamine amide Auxiliaries such as polybasic acid salt solution, 0.8 part of silicone-free foam-breaking polymer solution, and 0.4 part of polyester-modified polydimethylsiloxane solution are ground and dispersed for 1 hour, so that the particle size of the mixture after grinding and dispersing is 4 μm, so that Just be made into the A component of epoxy resin composition; Second step, take by weighing 19 parts of polyamide hardeners and 0.4 part of polyalkylphenol respectively and evenly mix and be made into the B component of epoxy resin composition; The first step is to weigh 230 parts of xylene solvent as component C, and uniformly mix components A and B to form an epoxy resin composition.

Embodiment 2

[0044]In the first step, weigh 120 parts of environmentally friendly bisphenol A epoxy resin, 95 parts of titanium dioxide, 2.5 parts of fumed silica and 36 parts of xylene, grind and disperse at high speed with a ball mill for 3 hours, and then add 4.0 parts of polyamine amide Auxiliaries such as polybasic acid salt solution, 0.9 part of non-organic silicon-free foam-breaking polymer solution, and 0.5 part of polyester-modified polydimethylsiloxane solution are ground and dispersed for 1 hour, so that the particle size of the mixture after grinding and dispersing is 4 μm, so that Just be made into the A component of epoxy resin composition; Second step, take by weighing respectively 22 parts of polyamide hardeners and 0.5 part of polyalkylphenol evenly mix and be made into the B component of epoxy resin composition; Step, weigh 295 parts of xylene solvent as component C, and uniformly mix component A and component B to form an epoxy resin composition.

Embodiment 3

[0046] In the first step, weigh 80 parts of environmentally friendly bisphenol A epoxy resin, 79 parts of activated calcium carbonate, 1.0 parts of fumed silica and 21 parts of xylene, grind and disperse at high speed with a ball mill for 3 hours, and then add 1.6 parts of polyamine amide Polybasic acid salt solution, 0.4 part of silicone-free foam-breaking polymer solution, 0.3 part of polyester-modified polydimethylsiloxane solution and other additives were ground and dispersed for 1 hour, so that the particle size of the mixture after grinding and dispersion was 4 μm, Like this just be made into the A component of epoxy resin composition; Second step, take by weighing 16 parts of polyamide hardeners and 0.3 part of polyalkylphenols uniformly mix respectively and be made into the B component of epoxy resin composition; Three steps, weighing 210 parts of xylene solvent as component C, and uniformly mixing component A and component B to form an epoxy resin composition.

Abstract

The invention discloses an environment-friendly epoxy resin composition as well as a preparation method and application thereof. The composition is mainly prepared from epoxy resins and an amine curing agent, and is additionally provided with appropriate auxiliaries such as curing accelerator, moist dispersing agent, defoamer, flatting agent and the like, filling materials and xylene serving as asolvent. After being cured, the composition has good adhesive force, and excellent comprehensive performances such as mechanical performance, waterproof performance and anti-corrosion performance, and can be widely used in terrace, adhesive, anticorrosive paint and the like.

Description

technical field [0001] The invention relates to an epoxy resin composition and a preparation method thereof, in particular to an epoxy resin composition which can be used for floors, adhesives, anti-corrosion coatings, etc., and a preparation method and application thereof. Background technique [0002] Epoxy resin refers to a polymer compound containing two or more epoxy groups, which is widely used in consumer fields such as coatings, composite materials, electronic appliances, and adhesives. [0003] There are many types of epoxy resins, which can be divided into bisphenol A type, bisphenol F type, novolac epoxy resin and aliphatic epoxy resin according to the composition. Epoxy resin has high mechanical properties, strong cohesion, dense molecular structure; excellent bonding performance; small curing shrinkage (stable product size, small internal stress, not easy to crack); good insulation; good corrosion resistance; good stability; Good heat (up to 200 ℃ or higher), s...
