Abstract

COLD RUBBER LIQUID RUBBER. Comprised of a formulation of a chemical compound, solvent-free, which is intended to provide a liquid waterproofing agent with a high solids content which, after curing, forms a monolithic mat of exceptional impermeability, elasticity, strength and physicochemical stability, for application in basements, retaining walls, concrete slabs, planters, swimming pools, water tanks, cold areas, metal or concrete gutters, external walls, precast concrete, metal roofs and others.

Description

"COLD VULCANIZED COLD RUBBER".

The present patent application refers to a "COLD VULCANIZED LIQUID RUBBER" which has been developed with a new formulation of a solvent-free chemical compound which is intended to provide a high water content liquid waterproofing agent. solids, which upon curing form a monolithic blanket of exceptional impermeability, elasticity, strength and physical and chemical stability, for application in waterproofing: baldrames, retaining walls, concrete slabs, gardeners, swimming pools, water reservoirs, cold areas, metal or concrete gutters, external walls, precast concrete, metal roofs and others.

Currently, it is known the wide use of waterproofing products for application in building elements, such as: blocks, bricks, cladding boards, tiles among others, and said waterproofing for this type of application are usually in liquid form, and They are applied by means of brushes, brushes, guns, dipping, spraying and others.

It is also well known that the vast majority of known waterproofers have some considerable drawbacks, such as large sudden variations in temperature, reducing their efficiency. Other waterproofing materials have the drawback of forming a film with low elasticity over the waterproofed construction element, often resulting in the formation of cracks in this film, thus compromising the waterproofing. In turn, many of the other waterproofing agents known in the art still have other drawbacks, such as: presence of organic solvent, odor, low durability, low elasticity, requiring maintenance and reapplication in a relatively short period of time, and these waterproofing agents are still considerably sensitive. the attack of other chemical, and even biological, such as fungi among others, which often results in inconvenience for the owner of the work, which ends up doing corrective waterproofing work, thus increasing the costs of construction.

PI 0700744-2 deals with a waterproofing compound composed of 5% (five percent) n.octyl triethoxysilane, plus a portion of 95% (ninety five percent) of turpentine. Also considered efficient are the mixtures of 2.5% (two point five percent) of n.octyl triethoxysilane, plus 973% (ninety seven point five percent) of turpentine, up to 15% (fifteen percent) of n.octyl triethoxysilane. , plus 85% (eighty-five percent) of turpentine.

Already the patent PI 9506128-2, deals with A Synthetic Rubber used for processing has the following properties:

In order to reach a satisfactory quantity for the transformation of Synthetic Rubber to liquid, light colored granulated Synthetic Rubber 500 gr; Sturene Monomer 500 ml .; White pigment 100gr, Additivated Gasoline 3,700 ml. The components are used in sequence until reaching the ideal emulsion and viscosity for application and as the used colorless light-colored rubber and may, depending on the needs, add the desired pigmentation color. It was applied on a 3.50 m2 slab, the yield with 2 coats that is enough for perfect waterproofing, was spent 3 ^ 700 ml.

To realize the transformation mode is used.

01 Mixing of 04 blades.

Adding the products in the following order.

500 gr Styrene Monomer; 100 gr. White Pigment;

500 gr of granulated Synthetic Rubber as it is diluted, gradually add 2,700 ml of Additive Gasoline, corresponding to an official gallon measure.

The present invention consists of a "COLD VULCANIZED RUBBER" which is a surface sealer with high solids, high elasticity, excellent adhesion and durability, whose compositions follow the following formulations:
