What are the factors affecting the bonding function between epoxy floor paint and concrete? The main factors affecting the bonding function between epoxy floor paint and concrete can be divided into two parts: the situation of concrete base and the situation of epoxy floor. First of all, it should be ensured that epoxy floor paint can adhere to concrete well, that is, they can not be strongly bonded together. There can be no shedding phenomenon, so we must strictly control the bonding function between the two.
I. Conditions of Concrete Foundation
Coarse, dry and solid concrete surface with appropriate degree of solidified floor is the best concrete base surface.
1. Water content: The lower the water content of concrete base, the better the bonding function.
2. Solid ground: The ground is too loose, which will make the floor paint and the base have no bonding force. Therefore, all the loose layers should be removed before construction.
3. Porosity: As a kind of porous floor, the inner capillary of concrete is suitable for the immersion of floor paint.
The better the penetration and leakage of floor paint, the better the bonding function of the two, so the old concrete floor is generally.
Especially the base surface which has been smeared with other covering materials must be fully polished so that it has a certain degree of roughness and openings on the ground for construction.
Parking lot wear-resistant floor and floor, etc.
II. Situation of Epoxy Resin Floor Materials
1. Construction technology.
When the adhesion between the floor paint and the base is insufficient, the floor will fall off.
The most effective way to prevent falling off is to pay attention to the treatment of the base, which must be in a suitable rough and dry condition before floor construction can be carried out.
2. Curing reaction.
Floor paint belongs to reactive curing paint. The amount of heat released and the temperature produced during the reaction process have a great influence on the curing performance of floor paint.
Among them, curing agent is the main factor affecting the curing temperature, so in order to ensure the bonding strength between epoxy floor paint and the base, it is necessary to select the appropriate curing agent.
Epoxy resin floor paint is a thin film attached to the concrete base surface, in order to keep its function better.
First of all, it should be ensured that epoxy floor paint can adhere to concrete well, that is, they can not be strongly bonded together. There can be no shedding phenomenon, so we must strictly control the bonding function between the two.
