Embodiment 1-6

[0174] Examples 1-6: Evaluation of pads comprising composites according to the invention with water only (i.e. without cleaning enhancing additives) on floors with few surface irregularities:

[0175] In Table 3 below is summarized the use of Servomatic 43KA mechanized floor cleaner (single pad speed 160rpm) and water (without any cleaning enhancing additives) for industrial floor cleaning M-F resins and 33cm (13in) diameter pads of composite materials A, B, C, D and E observations in the evaluation.

[0176] table 3:

[0177]

[0178] *Pads are cut from blocks of M-F resin without subsequent manufacturing thermocompression

[0179] All the pads evaluated were considered to be good for the cleaning effect achieved on epoxy floors with R10 non-slip surfaces, but the pads of composites of type C, D and E according to the invention exhibited significantly longer (i.e. greater than 3030m (1000m 2 )) of moving life, in comparison, the movement of M-F resin pad without s...

Embodiment 7-12

[0180] Examples 7-12: Evaluation of mats comprising composites according to the invention with detergent-containing water on floors with few surface irregularities:

[0181] In Table 4 below is summarized the use of Servomatic 43KA mechanized floor cleaner (single pad speed 160rpm) and water with detergent (5 Brix in 100mL in 3L of water, ie 0.17 Brix) M-F resins and A, B, C, D and E for industrial floor cleaning Observations in the evaluation of 33 cm (13 inch) diameter pads of type composites.

[0184] *Pads are cut from blocks of M-F resin without subsequent manufacturing thermocompression

[0185] All the pads evaluated were considered to achieve a good cleaning effect on epoxy floors with an R10 non-slip surface, i.e. better than figure 1The cleaning effect with water (without the cleaning boost additive) was observed for pads of type D shown, but pads of composites of types C, D and E according to the invention exhibited significantl...

Embodiment 13-18

[0186] Examples 13-18: Evaluation of mats comprising composites according to the invention with water with detergent (5 Brix in 100 mL of water, ie 0.17 Brix) on floors with R10 non-slip surfaces :

[0187] Table 5 below summarizes the results obtained using NLL332 Mechanized floor cleaner (with reservoir but no water absorption) and water with detergent (5 Brix of detergent in 100 mL of 3 L of water, ie 0.17 Brix) M-F resin for cleaning non-slip R10 industrial floors As well as observations in the 33 cm (13 inch) diameter pad evaluation of Types A, B, C, D and E composites.

[0190] *Pads are cut from blocks of M-F resin without heat compression

[0191] All the pads evaluated were considered good for the cleaning effect achieved on non-slip R10 industrial floors, i.e. inferior to the cleaning effect achieved on smoother floors, and all pads were considered poor for their ability to cope with floor irregularities. At least good, the capa...

Abstract

A process for producing a composite material comprising the steps of: providing mm-sized particles comprising at least particles of a porous optionally at least partially compressed open-cell melamine formaldehyde resin and mm-sized particles of at least one non-rigid foamed resin; mixing said particles with at least one reactive adhesive in a concentration of 6 to 18 g of reactive adhesive per 100 g of mm-sized particles; reacting said reactive adhesive with said particles in the presence of aerial moisture thereby bonding said particles together during said mixing process; transporting said mixture into a mould; and irreversibly compressing said mixture to a block in a mould without additional heat to a density greater than 50 kg / m 3 to form a block of said composite material; a composite material obtainable by this process; and the use of this composite material for polishing and / or cleaning applications with a liquid.

Description

technical field [0001] The present invention relates to a composite material, a method for its manufacture and its use. Background of the invention [0002] Melamine-formaldehyde (M-F) resin is a cross-linked resin produced by condensation of melamine and formaldehyde. It has flame retardancy (no need to add flame retardants), chemical resistance, application temperature up to 240°C, abrasion resistance, and constant physical properties over a wide temperature range. Porous open-cell M-F resins, also known as open-cell melamine resin foams, additionally have low weight, good thermal insulation, high sound insulation capacity and low-temperature flexibility. Porous open-cell M-F resins are used as thermal and acoustic insulation and also as cleaning abrasives. [0003] Thermoforming is a standard method for providing thermal and acoustic insulating materials with a well-defined shape, used eg in the automotive industry. Thermal compression is also used to produce cleaning ...
