Description
Technical Field
The invention relates to high-molecular easy-care daub and a preparation method thereof, belonging to the technical field of high-molecular easy-care daub.
Background
A high-molecular easy-to-use daub is a non-toxic and tasteless rigid water-proof adhesive material which is made up by mixing several high-molecular materials with silicate cement and powdered sand according to a certain proportion and adopting scientific proportioning and special technological process and integrates the functions of water-proofing, adhesion and leak-stopping into one body.
However, since some polymer materials are contained, which are flammable, their fire-retardant properties are not ideal, and if a fire occurs, the wall is damaged due to softening of the benefical mastic, so there is a high demand for a polymer benefical mastic with excellent fire-retardant properties.
Disclosure of Invention
The present invention provides a solution to the above problems.
The invention is realized by the following steps:
the polymer easy daub is characterized by comprising the following components in parts by weight: 20-30 parts of cement, 5-10 parts of aluminum dihydrogen phosphate, 40-50 parts of building fine sand, 0.05-0.2 part of hydroxypropyl methyl cellulose ether, 0.5-1.0 part of silicate fiber and 0.1-0.3 part of lignin fiber.
As a further improvement, the cement is portland cement. The Portland cement is a main gel material, and can ensure the compressive strength and the tensile bonding strength of the benefited daub.
As a further improvement, the silicate fiber is one or more of aluminum silicate fiber, calcium silicate fiber and magnesium silicate fiber, and is preferably aluminum silicate fiber. The silicate fiber is inorganic mineral fiber, has poor flammability, can improve the fireproof and fireproof performance of the beneficiary daub, and can permeate into capillary pores of silicate cement as the fiber to be crosslinked with the silicate cement, so that the breaking strength, the compressive strength and the tensile bonding strength of the beneficiary daub are improved.
As a further improvement, the building fine sand is 70-140 mesh grade sand. The building fine sand is used as a framework material, and is matched with the silicate cement and the silicate fiber to enhance the compressive strength of the beneficial daub. The selection of 70-140 meshes is very critical, and the sand preparation in the range can ensure the balance of the compressive strength and the binding power of the mortar and good crack resistance.
As a further improvement, the magnesium oxide powder also comprises 3-5 parts of magnesium oxide. The magnesium oxide has high fireproof and insulating properties, and the fireproof and fireproof properties of the beneficiated mortar can be greatly improved by adding the magnesium oxide into the beneficiated mortar. Wherein, the aluminum dihydrogen phosphate is used as the adhesive of the magnesium oxide, so that the magnesium oxide is firmly bonded with other raw materials such as cement, carbonate fiber and the like, and the breaking strength and the seepage pressure resistance of the beneficial daub are improved.
The preparation method of the polymer easy daub comprises the following steps:
s1, weighing cement, construction fine sand, aluminum dihydrogen phosphate and silicate fiber according to the proportion, mixing the weighed cement, aluminum dihydrogen phosphate, silicate fiber and construction fine sand accounting for 45-55% of the weighed construction fine sand, and uniformly stirring in a stirrer to obtain premix A;
s2: weighing hydroxypropyl methyl cellulose ether and lignin fiber according to a proportion, mixing, adding into the premix A in the step S1, and uniformly stirring in a stirrer to obtain premix B;
s3: and (4) adding the residual building fine sand in the step (S1) into the premix B, and uniformly stirring in a stirrer to obtain the high-molecular beneficial daub.
As a further improvement, in the step S1, the stirring time of the stirring is 50 to 80S.
As a further improvement, in the step S2, the stirring time of the stirring is 60 to 120S.
As a further improvement, in the step S3, the stirring time of the stirring is 3-5 min.
As a further improvement, the method also comprises the step of adding magnesium oxide in the step S2, mixing the magnesium oxide with other raw materials and then adding the mixture into a stirrer.
In the method, the main materials are fully and uniformly mixed in step S1, then the main materials and the auxiliary materials in step S2 are interacted, and finally the residual fine building sand is added, so that the defect that the binding property of the beneficial daub is poor due to non-uniform mixing and caking of the main materials is avoided, and the binding property and the compressive strength of the beneficial daub are improved. The stirring time of each step is also very critical, the stirring time in the step S1 is 50-80S, the stirring time in the step S2 is 60-120S, if the stirring time is too short, the stirring is not uniform, the bonding property of the beneficiary daub can be reduced, if the stirring time is too long, the main material and the auxiliary material are mixed and then dried and hardened, the interaction between the auxiliary material and the main material in the subsequent steps is not facilitated, and the properties of the beneficiary daub, such as water retention property, bonding property, compressive strength and the like, are difficult to guarantee.
The invention has the beneficial effects that:
1. the high-molecular beneficial daub disclosed by the invention contains a large amount of inorganic materials which are difficult to burn, such as cement, building fine sand, aluminium dihydrogen phosphate, aluminium silicate fiber, magnesium oxide and the like, so that the high-molecular beneficial daub has excellent fireproof and fireproof performances and reaches A level.
2. The high-molecular beneficial daub disclosed by the invention contains silicate fibers, silicate cement, building fine sand, aluminum dihydrogen phosphate and the like in proper proportion, and the synergistic effect is exerted, so that the beneficial daub is high in bonding strength, and can be used for effectively preventing cracks from generating, and preventing hollowing, cracking and alkali whitening.
3. The high molecular beneficial daub contains hydroxypropyl methyl cellulose ether and lignin fiber, so that the beneficial daub has high seepage pressure resistance and can prevent water from permeating from the veneer bonding layer.
4. The high-molecular beneficial daub has good workability, water retention property and sag resistance, can be constructed in a large area, and has high construction efficiency.
5. The high molecular easy daub of the invention is water-resistant, temperature-resistant, freeze-thaw resistant, nontoxic and pollution-free.
6. The high-molecular beneficial daub has high bonding strength and high permeation pressure resistance, and only needs a thin coating when in use, thereby reducing the material consumption and lowering the production cost.
