Description
Technical Field
The invention relates to C04B41, in particular to a universal stone protective agent.
Background
Hydrophilic hydroxyl and capillary holes exist in the stone, and the stone is exposed to the air environment for a long time and is easy to absorb air and moisture in the environment, so that the stone is carbonized, and reacts with alkali substances in the stone, and the alkalinity of the stone is reduced. The alkali substance can play a certain role in protecting the stone, and after the stone is carbonized, the protection is reduced, so that the stone is corroded. The erosion can occur to the stone materials such as marble bricks or cement bricks even after polishing, so that the stone materials are subjected to waterproof treatment, a surface protective agent is developed, and the method plays an important role in prolonging the service life of the stone materials and enhancing the structural performance of the stone materials.
There are several common types of protectants currently on the market: methacrylic resin type, organosiloxane type, organofluorosilicone type, water-based emulsion type, epoxy resin type, etc., but these protective agents all have a problem which is difficult to avoid and have low adhesion to stone while ensuring water-and oil-repellency.
Patent No. CN113233919A provides a novel stone protective agent and a preparation method thereof, wherein the anti-aging effect and the sterilization function of the protective agent are improved by adding tea polyphenol and tripterygium wilfordii extracts, and the waterproof and moisture-proof performances are improved by adding auxiliary reinforcing agents, so that the erosion of microorganisms is effectively reduced.
Disclosure of Invention
In order to solve the above problems, the first aspect of the present invention provides a general-purpose stone protective agent, wherein the general-purpose stone protective agent is characterized in that the raw materials of the general-purpose stone protective agent include a modified resin, a flame retardant synergist, a wetting agent, and a stabilizer.
As a preferred technical solution of the present invention, the modified resin is selected from one or more of dipropylene polyurethane, epoxy modified polyurethane dispersion, and silicone modified polyurethane.
As a preferable technical scheme, the flame retardant synergist is selected from one or more of silicon powder modified resin, phosphorus compounds and metal oxides.
Silicon powder modified resin
The silicon powder modified resin is a novel silicon flame-retardant synergist, is siloxane powder with 100% of activity, and is commonly used for improving the processing performance of materials or improving the physical property and the flame resistance. In a high-filling flame-retardant system, the release of smoke and toxic gas can be reduced, the heat release rate is reduced, and the impact strength performance is improved.
As a preferred technical solution of the present invention, the wetting agent is selected from one or more of a silicone wetting agent, a fluoroalkyl polyether modified polysiloxane, and an ether modified silane.
In a preferred embodiment of the present invention, the stabilizer is one or more selected from polyethylene glycol monolaurate, hydroxypropyl methylcellulose, and polyethylene glycol stearate.
False adhesion often exists between the silicone protective agent and the stone, which can cause hollowing and loosening. The applicant has found in a large number of experiments that the addition of a specific hydroxypropyl methylcellulose to a repellent system not only ameliorates this problem, but also improves the water and oil repellency of the repellent. The applicant speculates that this may be due to the molecular chain entanglement of hydroxypropyl methylcellulose acting synergistically with other substances of the system; meanwhile, the methoxyl and the hydroxypropoxyl of the hydroxypropyl methyl cellulose are uniformly distributed along the main chain, the capability of forming hydrogen bonds by the oxygen atoms on the hydroxyl and ether bonds is improved, and the hydrophobic main chain is combined with other substance molecules through the hydrogen bonds, so that the space of free movement of the molecules is reduced, and the system adhesive force is improved.
As a preferable technical scheme, the universal stone protective agent further comprises silicon micropowder and distilled water as raw materials.
As a preferable technical scheme of the invention, the particle size of the silicon micro powder is 600-1250 meshes.
Preferably, in the fine silica powder, fe 2 0 3 Is less than 0.05 percent, and Al 2 0 3 Mass fraction of less than 0.3%, tiO 2 The mass fraction of CaO is less than 0.04 percent, and the mass fraction of CaO is less than 0.02 percent.
Silicon micropowder
The silicon powder is a byproduct of smelting metal, and the chemical composition of the silicon powder has certain difference due to the fact that the silicon powder is a reaction byproduct. The silica powder can increase nucleation sites of hydration products, is beneficial to crystallization and nucleation of the hydration products, and is often used in the hydration process of cement.
The applicant finds that the specific silicon micropowder is added into a protective agent system in experiments, so that the adhesive force of the protective agent is improved, and the protective agent has certain cold resistance. The applicant speculates that the nanometer-level silicon powder is filled in the molecular gaps of the organic silicon modified resin and the organic silicon wetting agent, so that a more compact structure is formed between molecules, the particle size distribution of a system is influenced, and the stability of the system is improved. If the particle size of the fine silica powder is too large, the ability of the fine silica powder to be filled is lowered, which is disadvantageous in system stability. In addition, the metal oxide in the silicon micro powder has certain reaction catalytic activity, so that the protective agent can be spontaneously catalyzed in the preparation process, the reaction is promoted to be stably carried out, and meanwhile, a small amount of metal oxide is mixed in a protective agent system and can be preferentially combined with air in the storage process of the protective agent, so that the air is reduced for protecting the protective agentThe influence of the agent improves the stability of the protective agent, and the protective agent can be stored for a long time. The molecular action of the system is especially that the grain diameter of the silicon powder is 600-1250 meshes, and Fe in the silicon powder 2 0 3 Is less than 0.05 percent, and Al 2 0 3 Mass fraction of less than 0.04%, tiO 2 When the mass fraction of CaO is less than 0.04 percent and the mass fraction of CaO is less than 0.02 percent, the stability effect is particularly remarkable, and the standing time is obviously prolonged.
In addition, after the compact structure is formed, the mold can be isolated to a certain extent, so that the product has a certain mildew-proof effect.
As a preferable technical scheme, the universal stone protective agent comprises, by weight, 14-23 parts of modified resin, 0.1-3 parts of flame-retardant synergist, 0.3-1 part of wetting agent, 0.1-0.3 part of stabilizer, 22-34 parts of silicon micropowder and 10-22 parts of distilled water.
More preferably, the raw materials of the universal stone protective agent comprise, by weight, 15-21 parts of modified resin, 0.2-2.5 parts of flame-retardant synergist, 0.3-0.75 part of wetting agent, 0.1-0.15 part of stabilizer, 22-32 parts of silicon micropowder and 10-20 parts of distilled water.
The invention provides an application of a universal stone protective agent, and the universal stone protective agent is used for marble bricks and cement bricks.
Compared with the prior art, the invention has the following beneficial effects:
(1) The waterproof and oilproof performance is ensured, and the adhesion with the stone is improved.
