Problems solved by technology

[0002] Commonly used aggregates for traditional terrazzo floors in China include gravel, glass, quartz stone, etc., which bring the advantages of beautiful atmosphere and non-slip to the overall floor, but the cost is high, the floor hardness is high, the elasticity is poor, it cannot meet the needs of quietness, and it is corrosion-resistant The effect is not good, so in some areas that have special functional requirements for the ground, such as hospitals, schools, nursing homes, etc., it is not effective when it needs to have the characteristics of ergonomics, quietness, and excellent physical and chemical properties.

Abstract

The invention discloses a method for preparing organic resin aggregate used for an elastic polyurethane mute terrazzo terrace. The method comprises the following steps: sequentially adding resin, a dispersing agent, a defoaming agent, a wetting and leveling agent, a leveling and defoaming agent, an anti-settling agent and a filler into a mixing tank, carrying out high-speed dispersion for 50 minutes in a state of keeping the rotating speed at 900-1200 r / min under a vacuum condition, then adding activation powder, continuing dispersing at a high speed for 15 minutes, and conducting mixing in the mixing tank; and after mixing is finished, taking a proper amount of mixed components, fully cooling the mixed components, adding color paste, quartz sand and an accelerant with corresponding proportions, starting dispersing at a high speed, starting uniform stirring, adding a curing agent in proportion by using a digital oscillator, carrying out uniform mixing, making a plate, and conducting granulating and detecting. The elastic polyurethane terrazzo terrace has good toughness and rigidity, meets comprehensive performance requirements on the elastic polyurethane mute terrazzo terrace, has high bonding strength with a resin layer and is not prone to falling.

Description

technical field [0001] The invention relates to the technical field of floor materials, and relates to a method for preparing organic resin aggregates for elastic polyurethane terrazzo floors. Background technique [0002] Commonly used aggregates for traditional terrazzo floors in China include gravel, glass, quartz stone, etc., which bring the advantages of beautiful atmosphere and non-slip to the overall floor, but the cost is high, the floor hardness is high, the elasticity is poor, it cannot meet the needs of quietness, and it is corrosion-resistant The effect is not good, so in some areas that have special functional requirements for the ground, such as hospitals, schools, nursing homes, etc., when ergonomics, quietness, and excellent physical and chemical properties are required at the same time, it appears to be ineffective. [0003] Aggregate is a granular material that acts as a skeleton or filling in organic / inorganic terrazzo floors. Aggregate, as the main raw ma...
