Problems solved by technology

[0004] However, the cement-based imitation natural cultural stone is limited by the characteristics of its own materials and the special requirements for process processing. At the same time, it is accompanied by floating color, blooming, bottom-through, color cast, etc. caused by the production process, and the engineering wall is efflorescence, cross Pollution and other reasons cause stains on the apparent effect of such products, which seriously affect the production cost and decorative effect, and bring serious economic losses to the enterprise. It is also a common problem in the industry; although there are products that use acrylic paint and water to pollute The way of post-repair alleviates the impact to a certain extent, but there is still a big gap in repair effect and durability

preparation example Construction

[0038] The present invention provides a cement-based repair paste after imitating the color of natural cultural stone and its preparation method and construction method. The specific operation steps are as follows:

[0039] 1) The main and auxiliary monochrome repair pastes, according to the required color requirements or debugging in advance, prepare one or more monochrome color pastes at the same time;

[0040] 2) First mix the liquid film-forming substance, modifier, wetting agent, thickener, film-forming aid, and defoamer first, and then use a high-speed disperser to disperse, and control the dispersion speed within 1200 revolutions / min. After being evenly dispersed, set aside. Then, after mixing Portland cement or fillers, pigments, plasticizers, thixotropic agents, anti-efflorescence agents, water, and defoaming agents at high speed, control the dispersion speed between 1200-2500 rpm, and mix them evenly. Perform a secondary mixing process with the standby mixed solution, an...

Embodiment 1

[0046] Step 1. According to the production requirements, aiming at the fading and efflorescence of a kind of imitation natural cultural stone---cultural brick A. To complete batch product repair in the factory, it is necessary to prepare a primary color slurry and a secondary color slurry. Color paste components include:

[0047]

[0048] The weight ratio of the corresponding auxiliary color paste components is:

[0049]

[0050]

[0051] Blow off the dust on the surface of the product to be repaired;

[0052] Prepare the main color paste with a viscosity of 90KU and the auxiliary color paste with 120KU for spare use. Use a spray gun with a diameter of 2mm. The main color is full spray or local spray, and the auxiliary color is spot spray. Order;

[0053] In order to maintain the effectiveness of spraying, a distance of 20cm from the product is appropriate, and the spray direction is at a vertical angle to the product. The entire product is sprayed layer by layer, keeping wet-on-wet ...

example 2

[0058] Example 2, according to the needs of the market and customers, aiming at the engineering efflorescence and pollution of the imitated natural cultural stone---cultural stone B; the main problem is the color deviation after the engineering cement paste pollution and local efflorescence; a main color needs to be formulated Mortar and a secondary color mortar, the main color mortar components include:

[0059] Step 1. According to the production requirements, aiming at the fading and efflorescence of a kind of imitation natural cultural stone---cultural brick A. To complete batch product repair in the factory, it is necessary to prepare a main color slurry and two auxiliary color slurry. Color paste components include:

[0060]

[0061]

[0062] The corresponding weight ratio of the first auxiliary color paste component is:

[0063]

[0064] The corresponding weight ratio of the second auxiliary color paste component is:

[0065]

[0066]

[0067] Perform surface treatment on cont...

Abstract

The invention provides cement-based cultured stone color post-repair slurry, a preparation method and a repair construction method thereof. By means of optimization of a cement-based nature cultured stone-imitated color post-repair formula, slurry being suitable for different spray-coating method is prepared, wherein the sequence of color forming is controlled to achieve a reverse thinking mode of product repairing. In addition, by means of spray-coating overlapping of main color slurry and auxiliary color slurry in a wet-to-wet manner, the slurry, after being dried, can form naturally merging so that the repair construction method can recover the original appearance of the product and is strong in operability. During the preparation method of the post-repair slurry, the separating-mixing operation is mainly to satisfy the difference of dispersion requirements of different components. The viscosity of the main color slurry and the auxiliary color slurry are 70-150 KU. The post-repair slurry is scientific in formula, is outstanding in performance and is low in cost. The repair construction method is strong in operability, is natural in transition and is lifelike in repairing. The invention can solve and improve production and engineering repairing and the methods are feasible.

Description

Technical field [0001] The invention relates to a pigment paste, in particular to a cement-based cultural stone color post-fill paste. And its preparation method and construction method. Background technique [0002] Natural cultural stone generally refers to a decorative material carved from natural stone. To meet the needs of a certain architectural style, it is laid on the wall in the form of decorative veneer bricks, giving people a back-to-nature visual effect. It is a modern decoration One of the major mainstreams; with the advancement of science and technology and the improvement of people's living standards, people's requirements for building materials are also increasing. Limited by the lack of natural stone resources and the complexity of the processing technology, the rapid rise of a cement-based imitation natural cultural stone has also made this industry an unprecedented grand occasion; in villas, low-density real estate, hotels, clubs, gardening, etc. , Firmly occ...
