A kind of ultra-soft and ultra-thin composite rock slice and its preparation method

Abstract

The invention relates to a super-soft super-thin composite rock piece and a preparation method thereof, belonging to the field of new building materials. The super-soft super-thin composite rock piece contains an acrylate emulsion, a defoaming agent, color paste, a dispersing agent, a power raw material, a thickening agent, bentonite, a functional aid A, a functional aid B and the balance of water. The preparation method comprises the steps of sequentially adding the weighed materials into a container while stirring, uniformly stirring at a rotation speed of 300r / min-600r / min for 30-50 minutes so as to obtain a rock piece sizing agent, starting rock piece film forming stirring equipment to prepare a dried film, crushing the dried film in a crusher, and sieving. The super-soft super-thin composite rock piece is extremely low in liquid absorption rate and is soft, good in tenacity and unlikely to break after being put into water; the filminess can be realized, and unfavorable conditions of water resistance difference, fading, color blending, crushing and the like can be avoided; and the rock piece has excellent after-tack resistance and can be cured through a high temperature, a light wave or other manners.

Description

technical field [0001] The invention belongs to the field of new building materials; in particular, it relates to an ultra-soft and ultra-thin composite rock slice and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, people gradually pay more attention to environmental protection awareness, health awareness, and decoration fashion awareness. They not only require beautiful and generous decoration, but also care about environmental protection, health, light weight, and energy saving; composite rock slices are a kind of A kind of raw material for granite paint, which can be added and mixed with various water-based stone paints (real stone paint) in a certain proportion to become high-grade granite paint (lacquer). Granite paint (paint) breaks through the difficulty of real stone paint colorful spraying construction, and can achieve the wonderful effect of natural texture of colorful granite fire surface w...

Problems solved by technology

[0003] The problems existing in the rock flakes currently on the market are: the rock flakes have poor water resistance, and when the rock flakes are made into paint, they can only be sprayed quickly, otherwise the wet strength will decrease after soaking for a long time; they will be broken after spraying and stirring, which will seriously affect the construction efficiency and effect.

Long-term water immersion will lead to great elasticity of wet rock slices, which is a sign of poor water resistance. The thinner the rock slices, the less water-resistant and lower the wet strength. Most rock slice manufacturers can only choose to make thick slices and hard slices; rock slices Hard and relatively hard rock flakes are fragile; if they are mixed with colored sand, the hard flakes and colored sand will be crushed when they are ground against each other; the rock flakes are thick, and more powder is used, and the wrong choice of emulsion results in thick but liquid absorption. High means poor water resistance; discoloration, color mixing, and brokenness are typical defects; due to poor emulsion, the rock slices will become viscous even after repeated drying, and the finished product will be caked and agglomerated in transportation and storage; the rock slices are hard and thick and cannot be thin and light ;It will splash during construction spraying, and it will show unevenness or straight insertion on the wall surface
