Problems solved by technology

However, the traditional composite rock flake slurry has poor mechanical properties and water resistance. When the rock flakes are made into paint, they can only be sprayed quickly, otherwise the strength will decrease after long-term soaking, and it is easy to spray and stir again. Broken, faded and curled, which seriously affect the construction efficiency and decorative effect; in addition, due to the influence of the emulsion, repeated drying of the composite slab slurry will also cause a large return viscosity, and the composite slab slurry will cause the stack to be too thick due to the high return viscosity , It is easy to cause serious spraying gun blocking and chipping, which seriously affects the construction efficiency and decorative effect, and limits the market application of imitation granite paint

Abstract

The invention discloses a composite rock slice slurry. The composite rock slice slurry comprises a component A and a component B, and the component A comprises, by weight, 2-15 parts of a pigment slurry, 5-25 parts of a zeolite liquid and 30-90 parts of an aqueous hydroxypropene dispersion; the pigment paste comprises a pigment, a coupling agent and a directional agent; the zeolite liquid comprises a zeolite powder, a hydrophobic agent and a wetting agent; the component B comprises 70-90 parts by weight of a water-dispersible isocyanate curing agent; and a weight ratio of the component A to the component B is (5-7):1. The pigment slurry, the zeolite liquid, the aqueous hydroxypropylene dispersion and the water-dispersible isocyanate curing agent synergistically act according to a certain ratio to form the composite rock slice slurry, and composite rock slices prepared from the composite rock slice slurry have the characteristics of excellent wear resistance, excellent water resistance,excellent color retention, short curing time, no after-tack and good storage stability.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite rock slice slurry and a preparation method thereof. Background technique [0002] The imitation granite paint decoration has beautiful appearance, realistic effect, good water and weather resistance, and is increasingly favored by people. Natural rock flakes or artificial composite rock flakes are an important raw material for imitation granite paint. [0003] Natural rock slices are an important part of melange. Natural rock flakes have strong color retention, water resistance, and strong simulation, and have excellent heat and cold resistance. They are not sticky when hot, and are not brittle when cold. They are rich in color and bright, and have strong plasticity. excellent partner. Natural rock slices are mostly made of marble and granite through multiple processes such as crushing, crushing, washing, grading, and packaging. It also involves the mini...
