REFRACTORY MORTAR INSULATING THERMAL AND / OR ACOUSTIC DRY AND HOMOGENEOUS AND / OR MOIST, FOR INTERNAL AND EXTERNAL COATING ”

The present invention patent deals with improvements made (plaster / plaster) of wall, subfloor and closing masonry; manual and / or designed, in which the user only needs to add the amount of water recommended by the manufacturer.

[001] The present invention relates to a dry and homogeneous final refractory mass, composed of expanded vermiculite, fine aggregate (quartz and / or artificial sand), calcium and / or magnesium carbonate, CP III 40 cement, it can be replaced by cements (CP II32, CP IV and CP V) and special additives (cellulosic, polymeric, air incorporator, setting accelerator and retarder), going through the batch (trace) and / or continuous homogenization process, after being packed in valved bags, paper and beg, ready for delivery, we also emphasize that the invention can be processed wet in a mortar plant and transported by concrete mixer trucks.

[002] Main feature of this invention is to obtain a dry and homogeneous mixture, easy to apply and store, valid for six months to one year, with a good performance, performance in the intended applications which is thermal and acoustic insulation in plastered walls (plastering), as well as refractory and ceramic brickwork and underlays, emphasizing that the formula basically consists of using a mineral material with thermo-acoustic insulation property (expanded vermiculite), bonded to other materials such as quartz sand and / or artificial, Portland cements and special additives (cellulosic, polymeric, air incorporating, accelerators, retarders), forming a composite, where the professional only adds the water recommended by the manufacturer.

[003] Using the raw materials in the appropriate proportions as specified below, going through the batch (batch) and / or continuous homogenization process, being subsequently bagged for sale, but we emphasize that this product can also be processed via wet ( machined in mortar plant and

[007] The proportions provided above vary according to the characteristics inherent in the raw materials used, from region to region and at the time of manufacture of the product, and that in the formulations alumina also enters its composition to produce a mortar more resistant to high temperatures from 600 to 1200 ² C.

[008] The existence of previous orders, but which use different chemicals, reagents and binders, such as lime and clay, whose technique and the final product are totally different from the specified product is that the formulation uses aggregates with different particle sizes in their respective formulations .

[009] The thermo-acoustic mortar has an apparent mass in the hardened state of 0.800 g / cm ³ , which can vary from more or less 0.100 g / cm ³ , potential tensile strength of 0.35 Mpa, which can vary from more or less 0.05 Mpa, and compressive strength of 5 Mpa, with a variation of more or less 1.5 Mpa, in compliance with (NBR 13281) - Mortar for laying and wall and ceiling covering.

[010] And it manifests a compatibility in a raw material (expanded vermiculite), in the following orders that (BR - PI 8104751, BR-PI7600710, US-4293341, US-4564547, US-4043862, US-3600312, GB-1158460, GB-2067174, GB-1591801, GB1593383, PI-0404995).
