LT5222B - Adhesive-oily filler - Google Patents

Abstract

The present invention relates to structural fillers. Said filler is useful to smoothing wooden, concrete, plastered, coloured and made of gypsum card-board inner surfaces prior to painting with distemper, water-dispersable, oily and pentaphtalic paints and prior to hanging wall-paper. The adhesive-oily filler claimed consists of (in mass %): excipient, such as calcium carbonate (40-80); binding material, such as carboxymethylcellulose 90,5-60; preservative (0,5-3); oil "oxol" (1-10); household soap (0,2-0,6) and water - up to 100.

Description

The invention relates to building coatings. It is used to smooth the interior of wooden, concrete, plastered, painted, drywall surfaces before applying them with glue, water dispersion, oil and pentaphtal paints, as well as before gluing wallpaper.

The closest solution to the proposed solution by component is a building putty containing (by weight): polyvinyl alcohol 1.1-2.0; oil-oxole 5-10; household soap 0.7-1.1; chalk 100; water 25-35. (See USSR Authorized Certificate No. 316671, CO4B 25/00).

The main disadvantages of this putty: poor adhesion to the building ground, forming an airtight film, the wall can not "breathe", mold, does not exhibit elasticity, plasticity.

Interior decoration requires a "breathable" putty.

The purpose of the invention is to improve the adhesion of the building putty to the putty surface, moisture resistance, water vapor permeability, increase elasticity, ductility, sanding ease, achieve a smooth and smooth surface, good paint adhesion.

The object is achieved by the additional addition of a preservative in the following ratio (w / w) of the adhesive oil filler consisting of filler, binder, oil oxole, soap and water, using as a binder carboxymethylcellulose:

Calcium carbonate 40-80 Carboxymethylcellulose 0.5-6 Preservative 0.5-3 Oil oxol 1-10 Household soap 0.2-0.6 Water up to 100 The present invention has the essential difference. Adhesive oil filler adhesion,

uses carboxymethylcellulose to increase elasticity. The use of this component not only improves the properties of the putty, gives the desired consistency, but also makes the finished product cheaper.

The following materials are used for glue oil filler:

* filler - calcium carbonate - natural crushed or ground chalk.

The chalk content is 40 - 80% by weight. The introduction of a larger quantity is technologically impossible and a smaller quantity is impractical. A smaller amount decreases the coating power of the putty, i.e. y. the coated surface becomes thinner, which increases the surface roughness.

* binder - carboxymethylcellulose - adhesive. The adhesive binds the filler particles to each other, improving the plastic properties of the coating. The optimal amount range is 0.5-6% by weight. In smaller quantities, the above effect is undetectable, and with a significant increase in the amount of glue, the desired properties change insignificantly, increase hardening and increase the price of the product.

* Preservative - Acticide SPX. The preservative extends the life of the putty. It takes up 0.5-3% by weight.

* oil oxole. Oxol binds the filler particles to each other, improving the elastic properties of the coating. The optimum amount range is 1-10% by weight. At lower levels, the above effect is undetectable, and with a significant increase in oxole content, the desired properties change insignificantly and the product price increases.

* household soap, which improves the properties of putty, elasticity of processing elasticity. The optimum amount ranges from 0.2 to 0.6% by weight. At lower volumes, the desired effect is not achieved, and when the volume is increased significantly, the elasticity of the putty is impaired.

Examples of glue oil filler are given in Table 1.

The adhesive oil filler is produced as follows:

70 liters of water and 3 kilograms of carboxymethylcellulose - glue are poured into a metal container with a stirrer. The glue is mixed with the water until completely dissolved. Add 2 kilograms of oxol and 200 grams of household soap to the prepared mass. Mix well until homogenous. Stir for 10-15 minutes. This is followed by the addition of 130 kilograms of calcium carbonate. Stir the mass for 10 minutes. When the mixer is switched off, the mass is visually checked.

It must be homogeneous, free of extraneous mechanical and greasy impurities, and free of any signs of rancidity. The mass is then transferred to a grater. A white viscous mass is formed. Putty is packed in plastic containers. The container is hermetically sealed with a lid and placed in polyethylene bags and bound.

The properties of glue oil filler are determined by tests. It takes 3 substrates for each putty sample. The surface to be coated must be firm, dry, free of dust, dirt, grease, grease, wax, old paint residue. Cured putty does not crack, is hard, smoothes easily, adheres well to the putty surface. It shrinks well when dry, no cracks. Grinding does not break the substrate, does not stain.

The present invention improves the adhesion of adhesive oil filler to the surface to be coated, moisture resistance, water vapor permeability, increases elasticity, ductility and ease of sanding. After sanding, the surface is smooth and smooth, and the paint adheres well. Made from environmentally friendly materials, non-toxic in production and use.

Before putty, the pebbles surface is primed to bind the dusty, porous surface. The adhesive oil filler can be applied up to 3 mm in a continuous coat 2-3 times, first in the vertical direction, then in the horizontal direction, and the third - in the correction of errors. Surfaces that are smeared should be primed with soap primer 24 hours prior to application. There must be a 3 hour time period between each coat to allow the layers to dry. This smooths out the roughness of the plaster. It is easier to sand, resulting in lower labor costs and easier smooth surface. It is suitable for cementitious, lime, gypsum, water-based or water-based paints, gypsum plasterboard.
