Description

Ceramic stone adhesive and preparation method thereof

The invention relates to an adhesive for ceramic and stone building decoration materials and a preparation method thereof.

At present, with the progress of society, people have higher and higher requirements for building decoration, and various natural stone materials and various exquisitely crafted ceramic finishes emerge in an endless stream. People commonly use stone materials such as marble, granite, and ceramic finishes such as ceramic tiles, glazed tiles, mosaics, etc., and the adhesives for pasting these decorative fabrics are mainly cement mortar. The cost is higher, and the separation is serious, and the construction is very inconvenient, especially the sticking of the top plate is very difficult, labor-intensive and time-consuming.

The object of the present invention is to provide a ceramic stone adhesive with simple and convenient construction, low cost, strong adhesive force, water resistance, acid and alkali resistance and climate change resistance and its preparation method.

The present invention is accomplished in the following manner: the ceramic stone adhesive is made up of sizing material A and powder material B, wherein:

Glue A is made up of polyvinyl alcohol, acrylic acid, formaldehyde, ferric chloride, urea, hydrochloric acid, water glass, and the weight percent of component is:

Polyvinyl alcohol 50-60, acrylic acid 0.5-1, formaldehyde 20-30, ferric chloride 0.05-0.1, urea 5-10, hydrochloric acid 5-8, water glass 1-2;

Powder B is composed of sepiolite, calcium hydroxide, quartz sand and cement. The weight percentage of the components is: sepiolite 20-30, calcium hydroxide 10-15, quartz sand 20-30, cement 25-40 .

The weight percent of the components of the rubber material A is: polyvinyl alcohol 60, acrylic acid 0.5, formaldehyde 25, ferric chloride 0.05, urea 7, hydrochloric acid 6, water glass 1.45;

The weight percent of the components of powder B is: sepiolite 28, calcium hydrochloride 10, quartz sand 30, cement 32.

To prepare rubber material A, add 50-60% polyvinyl alcohol into water and heat up to above 92°C to dissolve. 8 React for 5-20 minutes, then add formaldehyde 20-30 and ferric chloride 0.05-0.1 to react until white micelles precipitate, immediately cool down to 40°C-70°C, and add urea 5-10°C to cool down to room temperature Finally, increase the stirring speed to redissolve the micelles into a gel solution, add water glass 1-2, and stir evenly;

Prepare powder B by pulverizing sepiolite 20-30 and quartz sand 20-30 by weight percentage, mixing with calcium hydroxide 10-15, cement 25-40 and evenly sieving;

Mix 1 part of rubber A with 2 parts of powder B.

The ceramic stone adhesive and the preparation method thereof of the present invention have the advantages of simple manufacturing process, no waste gas emission, and no environmental pollution. The adhesive product is non-combustible, non-toxic, low in cost, easy to store and transport, convenient in construction and use, saves labor and materials, and can reduce the cost by 10%-30% compared with pasting decorative surface materials with cement mortar. The adhesive has fast initial curing speed, strong adhesion, excellent water resistance, acid and alkali resistance and climate change resistance, and is suitable for pasting ceramic stone building decoration materials.

Embodiment 1: Preparation of sizing material A First weigh each component by weight percentage: polyvinyl alcohol 60, acrylic acid 0.5, formaldehyde 25, ferric chloride 0.05, urea 7, hydrochloric acid 6, water glass 1.45, then polyvinyl alcohol Dissolve vinyl alcohol in hot water above 92°C, the weight of water is 6-7 times the weight of polyvinyl alcohol, add acrylic acid under stirring, cool down to 80°C-85°C, add hydrochloric acid to react for 5-20 minutes, then add formaldehyde and React with ferric chloride 0.05 until white micelles precipitate, immediately lower the temperature to 40°C-70°C, add urea at the same time, after cooling down to room temperature, increase the stirring speed to make the micelles redissolve into a gel solution, add water glass 1.45, stir evenly, that is, cost adhesive compound A. Rubber material A is stored in polyvinyl chloride plastic barrels for later use.

To prepare powder B, first weigh the components by weight percentage: sepiolite 28, calcium hydroxide 10, quartz sand 30, cement 32. Then crush the sepiolite and quartz sand, mix them with calcium hydroxide and cement, and sieve evenly to form the adhesive powder. Packed in a woven bag lined with a plastic film bag and stored in a dry place for later use.

Construction and use method: use one part of rubber material A and two parts of powder material B according to the weight ratio, mix the two groups of A and B, stir well and evenly into a paste, and then paste it. When pasting, apply the above-mentioned paste-like glue on the bottom surface of the ceramic or stone decorative material to be pasted or on the wall. The decorative material will be directly pressed on the wall and it will be immediately bonded and fixed on the wall. will fall. The adhesive after mixing A and B must be used within 4 hours, so as not to affect the quality due to curing.

Embodiment two: preparation method is identical with embodiment one, and it adopts following component content: the content of each component by weight percentage is:

Rubber material A: polyvinyl alcohol 55, acrylic acid 1, formaldehyde 28, ferric chloride 0.05, urea 7.95, hydrochloric acid 7, water glass 1.

Powder B: sepiolite 25, calcium hydrochloride 12, quartz sand 28, cement 35.

The use method of the adhesive prepared with the content of the above components is the same as that of Example 1.
