Benefits of technology

The present invention is a high pressure laminate that includes a first layer of resin impregnated paper and at least one layer of fiber reinforced veil. The laminate has a caloric value of lower than about 3.0 MJ / kg when tested in accordance with ISO 1716. The laminate may also include a second binder and filler. The fiber reinforced veil includes reinforcing fibers and a binder. The laminate may be more aesthetically appealing when the first layer is melamine impregnated decor paper. The method for making the laminate involves pressing the layers together at a high pressure and temperature while simultaneously heating them. The laminate may also include a thermally cross-linked urethane acrylate paint layer on the exposed face of the first layer. The technical effect of the invention is a high pressure laminate with improved aesthetic appearance and reduced caloric value.

Problems solved by technology

To date, this hasn't been achieved because no one has been able to meet the caloric value requirement and still achieve the desired mechanical properties and fire propagation characteristics.

example

[0047] Five examples of a high pressure laminate of the present invention were prepared. In the first (Example 1), five fiber reinforced glass veils were sandwiched between two layers of melamine formaldehyde impregnated decorative paper.

[0048] The glass fiber utilized in the glass veils was E-glass having a fiber diameter of 11 microns and a length of 10 mm. The glass veils each had a weight per unit area of 100 g / m2. The glass veils included a poly vinyl alcohol binder at a content of 16 weight percent.

[0049] The decorative paper layers each had a weight per unit area of 160 g / m2 including 80 g / m2 base weight paper and 80 g / m2 melamine formaldehyde resin.

[0050] The stacked layers of glass veil were then impregnated with a secondary binder and filler formulation including 21 weight percent phenol formaldehyde, 26 weight percent calcium carbonate and 53 weight percent aluminum hydroxide. The final glass veil weight was 1000 g / m2.

[0051] The stacked layers were pressed together at...

Abstract

A high pressure laminate includes a first layer of resin impregnated paper and at least one layer of fiber reinforced veil. Each layer of fiber reinforced veil includes binder and filler. The laminate is characterized by having a caloric value of lower than 3.0 MJ / kg when tested in accordance with ISO 1716. A method for producing this high pressure laminate is also provided.

Description

TECHNICAL FIELD AND INDUSTRIAL APPLICABILITY OF THE INVENTION [0001] This invention relates generally to high pressure laminates and more particularly to a high pressure laminate complying with prEN 13823 and having a caloric value of lower than 3.0 MJ / kg when tested in accordance with ISO 1716. BACKGROUND OF THE INVENTION [0002] High pressure laminates (HPL) are well known in the art and HPL panels are used, for example, as wall linings, for furniture, facade cladding, bench tops and the like. [0003] One of the most important parameters of HPL panels, especially in the building industry, is fire performance. Since 2003, all building materials in Europe must comply with prEN 13823 (reaction to fire tests for building products). This norm describes the Single Burning Item (SBI) test. A1 and A2 classification of additional caloric value measurement according to ISO 1716 is required. [0004] State of the art HPL panels are made fire retardant by using fire retardant kraft paper or by us...
