Abstract

A high density mineral fibre board having a formaldehyde free binder has acceptable strength and good dimensional stability.

Description

  • This invention relates to a mineral fibre insulating product having a low formaldehyde or formaldehyde free binder.
  • Industry standard binders used for fibre insulation, for example glass wool and rock wool insulation are based on phenol formaldehyde. Whilst such binders can provide suitable properties to the insulating products there has for some time been a desire to move away from the use of phenol formaldehyde, particularly due to environmental considerations.
  • Traditional polyester based binder systems have previously been proposed but have not gained acceptance in the insulation industry, particularly as their strength in holding the mineral fibres together, especially when exposed to moisture or weathering, has been perceived as insufficient.
  • To date, only one low formaldehyde based mineral insulation binder system has been used on an industrial scale on glass wool insulation; this is based on polyacrylic acid and supplied by Rohm & Haas. Unfortunately, the highly acid nature of these types of binders can cause excessive corrosion of manufacturing plant unless significant investment is made in acid resistant equipment. U.S. Pat. No. 5,977,232 discloses a formaldehyde free binder for glass wool insulation based on a polycarboxylic acid. European patent application EP1698598A discloses use of a corrosion meter to try to mitigate problems associated with polycarboxylic acid-based fibreglass binder resins. In addition, whilst the strength of these binders is acceptable for some applications it is not as good as the commonly used phenol formaldehyde based binders.
  • It has not been thought possible to provide a formaldehyde free binder system useable on an industrial scale that will confer characteristics to mineral wool insulating products that could match or even exceed those obtained with formaldehyde binders.
  • According to one aspect, the present invention provides a mineral fibre insulating board as defined in claim 1. Other aspects are defined in other independent claims. Preferred and/or alternative features are defined in the dependent claims.
  • As used herein, the term formaldehyde free means that the composition is substantially free from formaldehyde, preferably does not liberate substantial formaldehyde as a result of drying or curing and/or preferably comprises less than one part per million by weight of formaldehyde.
  • Desired characteristics of the mineral fibre insulation board can be assessed by measuring Ordinary Compression Strength and/or Weathered Compression Strength and/or change in thickness after autoclave.
  • The invention may be particularly useful in applications where dimensional stability of the insulation board is important. It is surprising that a formaldehyde free binder can confer the strength and/or dimensional stability that has been found.
  • The insulating board may be: a fire barrier; a fire protection; cladding for a building; a ceiling tile; a roof board; thermal insulation for high temperature machinery for example, generators, ovens and industrial plant; foundation wall insulation, for example for use in basements or in a wall or partition between a room and a layer of earth and/or rock. The insulating board may be used to provide thermal and/or acoustic insulation.
  • The cured binder content may be in the range 0.5% - 15% by weight determined for example by loss on ignition. A cured binder content of 0.5-5% by weight, particularly 1.5-3.5% by weight may provide suitable characteristics, particularly with respect to one or more of the products mentioned above.
  • The binder may:
      • be based on a reducing sugar; and/or
      • be based on reductosis; and/or
      • be based on an aldehyde containing sugars/and/or
      • include at least one reaction product of a carbohydrate reactant and an amine reactant; and/or
      • include at least one reaction product of a reducing sugar and an amine reactant; and/or
      • include at least one reaction product of a carbohydrate reactant and a polycarboxylic acid ammonium salt reactant; and/or
      • include at least one reaction product from a Maillard reaction.
  • The binder may be based on a combination of a polycarboxylic acid, for example citric acid, a sugar, for example dextrose, and a source of ammonia, for example ammonia solution. It may be based on a combination of ammonium citrate and dextrose. Where the binder is based on sugars and/or citric acid and/or comprises significant —OH groups, it is particularly surprising that such levels of performance can be achieved. It would have been thought that the —OH groups for example in the sugars and/or citric acid would be readily subject to hydrolysis and that this would be detrimental to strength, particularly weathered strength, and/or dimensional stability.
  • The binder may comprise a silicon containing compound, particularly a silane; this may be an amino-substituted compound; it may be a silyl ether; it may facilitate adherence of the binder to the mineral fibres.
  • The binder may comprise melanoidins; it may be a thermoset binder; it may be thermally curable.
  • The binder may be one of those disclosed in International patent application n° PCT/US2006/028929, the contents of which is hereby incorporated by reference.
  • The insulating board may have
      • a nominal thickness in the range 20 to 200 mm; and/or
      • a thermal resistance R of R≧1.7 m2K/W, preferably R≧2 m2K/W at a thickness or 100mm; and/or
      • a density in the range 100 to 200 kg/m3, particularly 130 to 190 kg/m3.
  • The density may be in the order of 110 kg/m3, for example in the range 100 to 120 kg/m3; it may be in the order of 140 kg/m3, for example in the range 130 to 150 kg/m3; in the order of 180 kg/m3, for example in the range 170 to 190 kg/m3. Such density can provide products with desirable characteristics.
  • The mineral fibres may be glass wool or rock wool; the fibres may have an average diameter between 2 and 9 microns or be microfibres of smaller diameter; they may have an average length between 8 and 80 mm.
  • The mineral fibres may be crimped.
  • The insulating board preferably has good stability in a High Temperature Shrinkage test. The performance in such a test generally depends upon the thickness and density of the board. Table 1 shows desired performance for a 80 mm thick board with a density of 150 kg/m3. The low level of High Density Shrinkage is particularly surprising as it was assumed that shrinkage is primarily determined by fibre composition and little influenced by the binder.
  • A non-limiting example of the invention is described below.
  • An aqueous binder was prepared by mixing together:
  • Approximate % by weight
    Powdered dextrose monohydrate 19.1%
    Powdered anhydrous citric acid  3.4%
    28% aqueous ammonia  2.6%
    Silane A-1100 0.07%
    Water 73.5%
  • This binder was used in the manufacture of a rock wool roof board on a standard manufacturing line, the binder being sprayed onto the fibres just after fiberising and the coated fibres being collected, assembled in to a mat, compressed and cured in the usual way.
  • The cured roof board had:
      • a binder content of about 3% by weight as determined by loss on ignition
      • a thickness of about 80 mm
      • a density of about 150 kg/m3
  • Desired characteristics and results achieved are set out in Table 1:
  • TABLE 1

  • The comparison in the table with a product that is equivalent other than containing a phenol formaldehyde binder shows that, surprisingly, the invention can provide improved dimensional stability, i.e. less change in thickness after autoclave and improved High Density Shrinkage.
  • Testing of Ordinary Compression Strength and Weathered Compression Strength:
  • Ordinary Compression Strength is determined according to British Standard BS EN 826: 1996 (incorporated herein by reference).
  • Weathered Compression Strength is determined according to British Standard BS EN 826: 1996 on samples that have been subjected to the following accelerated weathering procedure: samples are cut to size and then placed in a preheated autoclave and conditioned on a wire mesh shelf away from the bottom of the chamber under wet steam at 35 kN/m2 for one hour. They are then removed, dried in an oven at 100° C. for five minutes and tested immediately for compression strength.
  • In both cases, compression strength is determined in the direction of the thickness of the product; the dimensions of face of the samples in contact with the compression test apparatus are preferably 200 mm×200 mm.
  • Testing of Change in Tafter Autoclave:
  • The thickness of the samples is determined, for example in accordance with British Standard BS EN 823: 1995 and recorded. The samples are then placed in a preheated autoclave and conditioned on a wire mesh shelf away from the bottom of the chamber under wet steam at 35 kN/m2 for one hour. They are then removed, dried in an oven at 100° C. for five minutes and their thickness is immediately measured again. The change in thickness after autoclave is calculated as (((thickness after autoclave)−(thickness before autoclave))/(thickness before autoclave))×100.
  • Testing of High Density Shrinkage:
  • Four samples 100 mm×75 mm are cut at random from an insulating board to be tested using a band saw or equivalent to ensure square and straight edges. The width and length at the centre position of the top and bottom face is measured, for example using a metal rule in mm. The mean average length l1 and mean average width w1 is calculated from these measurements for each sample. For each sample, the thickness at the centre position of each edge of the sample is measured and the mean average thickness t1 calculated from these measurements.
  • Each sample is placed individually in the centre of a muffle furnace maintained at a temperature of 800° C. The sample is removed from the furnace after 30 minutes and allowed to cool to room temperature on a wire tray. When cool, the width, length and thickness of the sample is measured in the same way as before and the mean average width w2, length l2and thickness t2 calculated in the same way.
  • The shrinkage for the sample is calculated using the formula:

  • Shrinkage=(((lwt1)−(lwt2))/(lwt1))×100
  • The High Density Shrinkage is calculated as the mean average of the % shrinkage of the four samples.
