Abstract
Simulated granite in selected colors with increased levels of alumina trihydrate (ATH) and decreased amounts of pre-ground ATH-filled polymer particles of selected colors, and preparative process.
Description
SIMULATED COLORED GRANITE AND PROCESS Background of the Invention
This invention relates to simulated colored granite and its production, using filler of alumina trihydrate (ATH) in syrup and pre-ground particles of ATH-filled polymer.
This is an improvement for making simulated granite articles with colors other than black and white over U.S. Patents 4,085,246 (1978) and 4,159,301 (1979), both to Buser, Roedel and Vasilliou. U.S. Patent 3,775,364 (1973) - Duggins, describes casting and polymerization systems useful in the present invention. All three of these patents are hereby incorporated herein by reference.
U.S. Patent 4,544,584 - Ross (1985) describes technology for making simulated stone products including colorants. Summary of the Invention
The present invention provides a preparative process and a simulated granite article comprising
A. 60 to 99% by weight (based on weight of the article) of a matrix comprising
(1) 30 to 45% by weight (based on weight of the article) of methyl methacrylate polymer selected from the group consisting of methyl methacrylate homopolymers and copolymers of methyl methacrylate with alpha-beta-ethylenically unsaturated compounds, and
(2) 30 to 60% by weight (based on weight of the article) of alumina trihydrate particles having a maximum particle size less than
about 100 microns in the longest dimension;
B. 0.8 to 20% by weight (based on weight of the article) particles in the size range of 100 to 800 or 2000 microns comprising a matrix of methyl methacrylate polymer selected from the group consisting of methyl methacrylate homopolymers and copolymers of methyl methacrylate with alpha-beta- ethylenically unsaturated compounds, filled with (based on the weight of the particles) 50 to 70% by weight alumina trihydrate and up to 2.5% by weight pigment, having a clear to white color;
C. 0.1-10% by weight (based on weight of the article) of particles in the size range of 100 to 2000 microns comprising a matrix of methyl methacrylate polymer selected from the group consisting of methyl methacrylate homopolymers and copolymers of methyl methacrylate with alpha-beta-ethylenically unsaturated compounds, filled with (based on the weight of the particles) 0.1-2.5% pigment having a black color;
D. 0.1-10.0% by weight (based on weight of the article) of particles in the size range of 100 to 2000 microns comprising a matrix of methyl methacrylate polymer selected from the group consisting of methyl methacrylate homopolymers and copolymers of methyl methacrylate with alpha-beta-ethylenically unsaturated compounds, filled with (based on the weight of the particles) 0.1-2.5% pigment of selected color other than black and white; and
E. 0-1% by weight (based on the weight of the article) of pigments of selected colors in at least the matrix of A.
Detailed Description
In order to provide simulated granite articles with colors other than black and white and desirable aesthetics more economically, it has been discovered that the ATH content of the matrix should be increased above that normally used and to a particular narrow range within the general teachings of related art, while the content of ATH-filled particles should be decreased and appropriate pigments added to the particles. Optionally, the matrix can be pigmented at low levels. Since the particles can be more costly than the matrix resin, this permits cost savings.
Desirable sand-colored simulated granite can be made using brown and yellow pigmented particles, and pink to rose colored simulated granite can be made using red pigments in the particles. Similar pigments can be used in the matrix.
The content of ATH in the matrix is increased from a normal level near 30% to the range of 30 to 60%, preferably 45 to 55%. All parts, percentages and proportions are by weight, based on the weight of the article, except where indicated otherwise. Percentages of filler in pre-ground particles are by weight based on the weight of the particles themselves.
The content of pre-ground particles in the article preferably is down from a normally used 33% to 5-20%, more preferably at least about 10%. These changes, surprisingly, permit significant improvement in aesthetics with sustained physical, chemical and mechanical properties.
In the following examples and comparative test, formulations are presented which are processed as in the above-cited Buser et al patents and others known in the art to produce useful end product in the
form of flat sheet and shape such as kitchen sinks and bowls. The seive size series used are in the American Standard Sieve Series in which 25-50 mesh is 700-300 microns and 50-100 mesh is 300 to 150 microns.
The particles are preformed methyl methacrylate polymer (PMMA) filled with about 62 to 65% by weight ATH particles and comminuted by techniques known in the art, preferably cryogenically, to the indicated mesh sizes, which are all in the range of 100 to 800 microns. The total filler level is also indicated, showing how much ATH plus pre-ground particles are in the matrix syrup. Suitable pigments known in the art can be used.
The comparative test gave acceptable results but in different color families, black and white rather than sand or rose. For obtaining the colors other than black and white, the present invention is particularly useful.
