Problems solved by technology

[0004] However, the existing solvent-free epoxy floor coatings are inevitably exposed to ultraviolet radiation during use, and the paint film formed after curing of epoxy resin monomers containing benzene rings or carbon-carbon double bonds is prone to molecular chain breakage under ultraviolet radiation. , produce active free radicals, and easily produce yellowing groups under the action of oxygen in the air, making the paint film easier to absorb ultraviolet rays and degrade, forming a vicious circle
Aging is prone to occur, causing yellowing of the appearance and decline in mechanical properties, which seriously affects the service life

Embodiment 1

[0029] An anti-yellowing solvent-free epoxy floor coating of this embodiment is composed of the following raw materials in parts by weight: 30 parts of bisglycidyl hexahydrophthalate, and 20 parts of WANAMINE® 2110 epoxy curing agent.

[0030] After stirring evenly, prepare samples on tinplate sheets and cement boards.

Embodiment 2

[0032] A kind of anti-yellowing solvent-free epoxy floor coating of the present embodiment is made up of the following raw materials in parts by weight: 30 parts of bisglycidyl hexahydrophthalate, 0.3 parts of Tego-450 leveling agent, 0.5 parts of high tego-760w dispersant, 0.6 parts of tego-900 defoamer, 20 parts of WANAMINE® 2110 epoxy curing agent.

[0033] After stirring evenly, prepare samples on tinplate sheets and cement boards.

[0034] Compared with Example 1, after adding leveling agent, dispersant, and defoamer in Example 2, the paint film is smoother and the appearance effect is better.

Embodiment 3

[0036] A kind of anti-yellowing solvent-free epoxy floor coating of the present embodiment is made up of the following raw materials in parts by weight: 30 parts of bisglycidyl hexahydrophthalate, 0.3 parts of Tego-450 leveling agent, 0.5 parts of high tego-760w dispersant, 0.6 parts of tego-900 defoamer, 10 parts of chrome oxide green, 20 parts of WANAMINE® 2110 epoxy curing agent.

[0037] After stirring evenly, prepare samples on tinplate sheets and cement boards.

[0038] Compared with Examples 1-2, Example 3 has added toner and has bright colors.

Abstract

The invention relates to an anti-yellowing solvent-free epoxy floor coating, and belongs to the technical field of floor coatings. The epoxy resin composition comprises the following raw materials inparts by weight: 30-40 parts of modified epoxy resin and 20-30 parts of an epoxy curing agent. The floor coating has the advantages of being not prone to yellowing and aging, low in product viscosity,high in strength, easy to construct and the like.

Description

technical field [0001] The invention relates to a yellowing-resistant solvent-free epoxy floor coating, which belongs to the technical field of floor coatings. Background technique [0002] Floor coating is a kind of architectural coating that can decorate and protect the ground. It is usually painted on the surface of non-wooden substrates such as cement. It can provide people with a clean and tidy working or living environment, so it is widely used in underground parking lots. , industrial production workshops, public buildings and other ground decoration fields. [0003] Floor coatings are generally composed of film-forming substances, fillers, and additives. According to film-forming substances, they can be divided into different types such as epoxy resins, acrylics, polyurethanes, and alkyds. Epoxy floor is a floor material formed of epoxy resin as a film-forming material. It has strong adhesion to cement substrates. The coating film formed by curing has the characteri...
