Epoxy terrazzo dry paving process
A technology of epoxy water and process, which is applied in the direction of machine tools, grinders, and manufacturing tools suitable for grinding workpiece planes. It can solve the problems of complex process and high cost of terrazzo paving, so as to simplify the construction process, save materials, and reduce construction costs. effect of difficulty

Embodiment 1
[0019] A kind of epoxy terrazzo dry paving process, comprises the following steps:
[0020] Step 1: Clean up the concrete base, where the compressive strength of the base is greater than 25MPa, and then paint the base with an amount of 0.2kg / m 2 -0.4kg / m 2 ;
[0021] Step 2: Mix 9-11 parts of aggregate and 0.5-1.5 parts of resin according to the weight ratio and stir evenly, spread the well-mixed aggregate on the ground that has been primed, compact and finish;
[0022] Step 3: Coarse grinding for leveling, medium grinding, resin sealing, fine grinding to open the surface, and finally the overlay construction.
[0023] This process does not have high requirements on the concrete base, it does not need to be too flat, as long as the strength meets the requirements, the construction process is simplified and the construction difficulty is reduced. The amount of aggregate is much greater than the amount of resin, which saves more materials. The terrazzo floor prepared by this p...

[0025] 1. Basic system construction
[0026] Base treatment:
[0027] The flatness of the surface of the base layer, if the surface is very uneven, the materials used in the subsequent leveling process are different, the thickness is different, the strength of the base layer, and the lack of strength will cause the base layer to be damaged by force and affect the cracking risk of the upper terrazzo . Generally, the compressive strength is required to be greater than 25MPa.
[0028] Basic sealing layer (primer construction):
[0029] The material used in the construction of the foundation sealing layer is primer, which is usually a combination of epoxy resin and polyamide modified curing agent, with an amount of 0.2kg / m 2 -0.4kg / m 2 , according to the number of pores on the ground, the dosage is different.
[0030] Before construction, absorb the dust on the ground, and evenly scrape or roll the primer on the base ground with a roller or knife board to increase the adhesio...
