Embodiment 1

[0060] Five samples of the high pressure laminates of the present invention were prepared. In a first example (Example 1), five layers of fiber reinforced glass curtains were sandwiched between two layers of melamine formaldehyde impregnated decorative paper.

[0061]The glass fiber used in this glass curtain is E-glass with a fiber diameter of 11 microns and a length of 10 mm. Each glass curtain has 100g / m 2 weight per unit area. The glass curtain included polyvinyl alcohol binder at a content of 16% by weight.

[0062] The decorative paper layers each have a 160 g / m 2 weight per unit area, including 80g / m 2 Basis weight paper and 80g / m 2 Melamine formaldehyde resin.

[0063] The stacked layers of glass curtains were then impregnated with a formulation of secondary binder and filler comprising 21 wt% phenol formaldehyde, 26 wt% calcium carbonate and 53 wt% aluminum hydroxide. The final glass curtain weight is 1000g / m 2 .

[0064] at 100kg / cm 2 The stacked layers wer...

Embodiment 2

[0066] The glass fiber used in the product of Example 2 is E-glass with a fiber diameter of 13 microns and a length of 11 mm. The glass curtains each have a 50g / m 2 The weight per unit area and the polyvinyl alcohol binder are included at a content of 14 wt%.

[0067] The stacked layers of glass curtains were impregnated with a formulation of secondary binder and filler of 15 wt% melamine formaldehyde, 20 wt% calcium carbonate and 65 wt% aluminum hydroxide. The final glass curtain weight is 900g / m 2 .

[0068] at 50kg / cm 2 The stacked layers of the product of Example 2 were pressed together at a temperature of 145° C. for 20 minutes to prepare a laminate with a thickness of 3 mm.

[0069] Further examples 3, 4 and 5 of the invention are given together with examples 1 and 2 in table 1 below. In addition, for comparison, the table also includes corresponding measurements for representative prior art HPL (standard HPL) and prior art FR-HPL (flame retardant HPL) products. Th...

Abstract

A high pressure laminate includes a first layer (12) of resin impregnated paper and at least one layer (14,16) 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

[0001] Technical Field and Industrial Applicability of the Invention [0002] The present invention relates generally to flame retardant, high pressure laminates and in particular to high pressure laminates complying with prEN 13823 and having a heating value of less than 3.0 MJ / kg when tested according to ISO 1716. Background of the invention [0003] High pressure laminates (HPL) are well known in the art and HPL boards are used, for example, as wall linings for furniture, wall cladding, countertops and the like. [0004] One of the most important parameters of HPL panels, especially of HPL panels in the construction industry, is the combustion behavior. Since 2003, all building materials in Europe must comply with prEN 13823 (reaction to fire tests of building products). This specification describes the single combustion method (SBI) test. Classes A1 and A2 as measured by added calorific value according to ISO 1716 are required. [0005] Under the prior art, the HPL boar...
