LT5163B - Latex filler with marble aggregate - Google Patents

Abstract

The invention relates to building fillers. The latex filler with marble aggregate is used for smoothing over wood, concrete and plastered surfaces before painting. The new filler contains from 8 to 30 percent by weight of marble, from 0,3 to 3 percent by weight of antifoaming agent, from 5 to 20 percent by weight of carboxymethylcellulose, from 0,5 to 5 percent by weight of preservative, from 1 to 14 percent by weight of latex, from 0,2 to 0,6 percent by weight of soap and water to 100 percent by weight.

Description

The invention relates to building coatings. Used to dry wooden, concrete, plastered, painted, drywall surfaces before dry application with glue, water dispersion, oil and pentaphthalic paint. Latex marble filler is used to obtain a very smooth, smooth, mechanical scratch resistant, very high quality surface.

The closest solution to the proposed solution by component is putty containing (by weight): chalk 100; synthetic latex or urea resin 0.5-8.0; household soap 0.5-5.0; dry bone glue 1.5-5.5; acidic synthetic emulsion 1.0-4.5; water 32-52. (See USSR Auth. Certificate No. 587125, CO4B 25/02).

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, not resistant to temperature changes.

The purpose of the invention is to improve the adhesion of the building putty to the surface to be treated, its resistance to temperature changes, increase its elasticity, ductility, sanding ease, achieve a very smooth, smooth, mechanical scratch resistant, very high quality surface.

The object is achieved by adding a latex marble filler consisting of filler, binder, latex, agricultural soap and water, the new addition being the use of marble as filler, carboxymethylcellulose as binder, additionally containing anti-foaming agent, preservative, in the presence of for the following component ratio (percentage by weight):

Marble 30-70 Anti-dusting 0.3-3.0 Carboxymethylcellulose 0.5-9 Preservative 0.5-3 Latex 1-14 Household soap 0.2-0.6 Water up to 100 The present invention has the essential difference. Latex with marble filler

uses carboxymethylcellulose to increase adhesion and 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.

Uses the following materials for latex with marble filler:

* filler - very finely ground marble Omyacarb, Microblank.

Omyacarb, a very finely ground marble, has a Microblank content of 30-70% 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 is smeared with a thinner layer, the target is not achieved.

* anti-foaming agent - the mix does not foam when mixed and filled. It contains 0.3 to 3.0% by weight.

* 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 to 9% 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.

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

* latex - latex of acrylic styrene copolymer. Latex is an open microstructure material made up of millions of tiny interconnected cells with air gaps, so it has good air ventilation and moisture regulation. Latex resistant to deformation and aging, hygienic, antibacterial, antifungal material. Latex binds the filler particles to each other, improving the elastic properties of the coating. The optimum amount range is 1-14% by weight. At a lower amount, the above effect is undetectable, and by significantly increasing the amount of synthetic latex, the desired properties change insignificantly and the price of the product increases.

* household soap, which improves the properties, processing, elasticity and flexibility of the putty. 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 latex marble filler are given in Table 1.

Latex with marble filler is produced as follows: LT 5163 B

70 liters of water, 2 kilograms of anti-foaming agent and 9 kilograms of carboxymethylcellulose - glue are added to the metal container with a stirrer. Stir until the glue is completely dissolved. 7 kg of latex, 250 grams of preservative and 200 grams of soap are added to the prepared mass. Mix well until homogenous. Stir for 10-15 minutes. This is followed by the addition of 130 kilograms of very fine milled marble Omyacarb, Microblank. 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 latex marble 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 the latex marble filler to the glazed surface, resistance to temperature changes, increases elasticity of plasticity and ease of sanding. Deposition resistant, can be thicker. After sanding, the surface to be coated becomes extremely smooth, smooth, resistant to mechanical scratches, and adheres well to paint. Made from eco-friendly materials, non-toxic, manufactured and used. Can be glazed mechanically using a glazing unit.

Before putty to bind old dust, porous surface pebbles, the surface is primed. It is then coated with a latex marble filler.

Latex with marble filler can be applied in continuous layers up to 3 mm

2-3 times, first in a vertical direction, then in a horizontal direction and a third in a 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, which reduces labor costs and gives you an extremely smooth, smooth finish. It is suitable for plastering surfaces plastered with cement, lime, gypsum, as well as for wall repairs or water-based paints, for gypsum board panels.
