Description
クリアコーティング組成物の製造方法は、当業者には明白であろう。例えば、分散剤と反応性希釈剤(又はモノマー)を合わせた後に乾燥粉砕パーライトと混合して高固体分散系を作り出すことができる。この分散系を次に適切な樹脂及び光開始剤と合わせて混合してよい。代替実施形態では、パーライトを分散剤でプレコーティングしてよい。好ましくは、分散剤がパーライトを表面コーティングし、その結果、コーティング組成物は未だに液体形態でありながら有効な分散系が達成される。分散剤は、架橋反応に関与して、鉱物がコーティングに結合するのを助けることができる。
ポリマー樹脂は、ホモポリマー又はコポリマーの形成に適切であり得る。適切な例は、ポリアクリレート、ポリエステル、ポリアミド、ポリウレタン、ポリイミド、ポリ尿素、ポリエーテル、ポリシリコーン、脂肪酸エステル、並びにこれらのポリマー樹脂のアミン、アルコール、酸、ケトン、エステル、フッ化、及び芳香族官能化バージョン並びにそれらの物理的ブレンド及びコポリマーを含み得る。ポリマー樹脂は、コーティング組成物の総質量に対して約10wt%～約95wt%、又は約20wt%～約85wt%、又は約30wt%～約75wt%、又は約40wt%～約65wt%、又は約50wt%～約80wt%の量で存在し得る。
Methods of making clear coating compositions will be apparent to those skilled in the art. For example, a dispersant and reactive diluent (or monomer) can be combined and then mixed with dry ground perlite to create a high solids dispersion. This dispersion may then be combined with a suitable resin and photoinitiator and mixed. In an alternative embodiment, the perlite may be pre-coated with a dispersant. Preferably, the dispersant surface coats the perlite so that the coating composition is still in liquid form while achieving an effective dispersion. Dispersants can participate in cross-linking reactions to help bind minerals to the coating.
Polymer resins may be suitable for forming homopolymers or copolymers. Suitable examples are polyacrylates, polyesters, polyamides, polyurethanes, polyimides, polyureas, polyethers, polysilicones, fatty acid esters, and amines, alcohols, acids, ketones, esters, fluorides, and aromatics of these polymer resins. It may include functionalized versions as well as physical blends and copolymers thereof. The polymer resin comprises about 10 wt% to about 95 wt%, or about 20 wt% to about 85 wt%, or about 30 wt% to about 75 wt%, or about 40 wt% to about 65 wt%, or about It can be present in an amount from 50 wt% to about 80 wt%.
本発明のパーライトは、パーライト粒子を含む。パーライトは、膨張パーライト、例えば膨張粉砕パーライト、粉砕パーライト又はその混合物であってよい。
パーライトは、火山ガラスとしても知られる天然ガラスであり、ケイ質マグマ又は溶岩の急速冷却によって形成される。ほとんどの天然ガラスは流紋岩と化学的に等価である。粗面岩、石英安山岩、安山岩、ラタイト及び玄武岩と化学的等価な天然ガラスも知られているが、あまり一般的でない。用語「黒曜石」は一般的に濃色、ほとんどの場合黒色の塊状天然ガラスであり、シリカ(すなわち、SiO2)に富む。黒曜石ガラスは、そのシリカ含量に応じてサブカテゴリーに分類可能であり、最も一般的には流紋岩質の黒曜石(典型的に質量で約73%のSiO2含有)である(Berry et al., 1983)。
パーライト鉱石は、典型的に約72～75%のSiO2、12～14%のAl2O3、0.5～2%のFe2O3、3～5%のNa2O、4～5%のK2O、0.4～1.5%のCaO(質量で)、及び低濃度の他の金属元素を含有する水和天然ガラスである。パーライト鉱物は、高含有量(2～10質量%)の化学結合した水、ガラス質の真珠のような光沢、及び特徴的な同心円状又は弓状のタマネギの皮様(すなわち、パーライト状)割れ目の存在によって他の天然ガラスと区別される。
パーライト製品は、粉砕、ふるい分け、及び熱膨張を含み得る本明細書に開示の方法によって調製可能である。パーライト製品は、高空隙率、低いかさ密度、及び化学的不活性などの商業的に有益な物理的性質を有し得る。パーライト鉱石の品質及び加工方法に応じて、膨張パーライト製品を濾過助剤、軽量絶縁材料、フィラー材料、園芸用及び水耕用媒体、並びにケミカルキャリアとして使用することができる。
The perlite of the present invention contains perlite particles. The perlite may be expanded perlite, such as expanded ground perlite, ground perlite or mixtures thereof.
Perlite, also known as volcanic glass, is a natural glass formed by the rapid cooling of siliceous magma or lava. Most natural glasses are chemically equivalent to rhyolite. Natural glasses chemically equivalent to trachyte, dacite, andesite, ratite and basalt are also known, but less common. The term "obsidian" is generally a dark, most often black, massive natural glass rich in silica (ie, SiO2). Obsidian glasses can be divided into subcategories according to their silica content, most commonly rhyolitic obsidian (typically containing about 73% SiO2 by mass) (Berry et al., 1983).
Perlite ore typically contains about 72-75% SiO2, 12-14% Al2O3, 0.5-2% Fe2O3, 3-5% Na2O, 4-5% K2O, 0.4-1.5% CaO ( by mass), and low concentrations of other metallic elements. Perlite minerals have a high content (2-10% by weight) of chemically bound water, a vitreous pearly luster, and characteristic concentric or arcuate onion-skin-like (i.e., perlite-like) fissures. is distinguished from other natural glasses by the presence of
Perlite products can be prepared by the methods disclosed herein, which can include grinding , sieving, and thermal expansion. Perlite products can have commercially useful physical properties such as high porosity, low bulk density, and chemical inertness. Depending on the quality of the perlite ore and the method of processing, expanded perlite products can be used as filter aids, lightweight insulation materials, filler materials, horticultural and hydroponic media, and chemical carriers.
パーライトの加工は、鉱石の粉砕(破砕及び研磨)、ふるい分け、熱膨張、粉砕、及び完成品の仕様を満たすための膨張材料のエアサイズ分離並びに技術上周知の他の方法を含み得る。例えば、パーライト鉱石を破砕し、研磨し、所定粒径範囲に分類してから(例えば、30メッシュを通して)、分類された材料を空気中膨張炉(Neuschotz, 1947; Zoradi, 1952参照)内、870～1100℃の温度で空中加熱すると、同時のガラスの軟化と含有水の蒸発がガラス粒子の急速膨張をもたらして、未膨張鉱石の20倍までのかさ容積を有する泡状ガラス材料を形成する。膨張パーライトを次に最終製品のサイズ仕様を満たすように分類する。
膨張パーライトは、1つ以上のセル、又はセルの一部を含み、セルは、本質的にガラス壁によって部分的又は全体的に囲まれた空隙であり、通常はガラスが軟化状態のときにガスの膨張から形成される。所与の容積のガラス中のガス入り又は空のセルの存在は、同容積の固体ガラスに比べて低い遠心湿潤密度をもたらす。セルが閉じて空気が閉じ込められている場合、パーライトの粒子は液体上に浮くことができる。例えば、粉砕によるパーライトの破砕は、低湿潤密度という特性を保持し、濾過及び機能的フィラー用途に有用な特徴をも与える入り組んだセル構造を作り出すことができる。
Processing of perlite can include ore crushing (crushing and grinding), sieving, thermal expansion, crushing , and air size separation of expanded material to meet finished product specifications and other methods known in the art. For example, perlite ore is crushed, polished, and classified (e.g., through 30 mesh) to a predetermined size range, and the classified material is placed in an air expansion furnace (see Neuschotz, 1947; Zoradi, 1952) at 870 When heated in air at temperatures of ~1100°C, simultaneous softening of the glass and evaporation of the contained water lead to rapid expansion of the glass particles to form a foamy glass material with up to 20 times the bulk volume of the unexpanded ore. The expanded perlite is then classified to meet final product size specifications.
Expanded perlite contains one or more cells, or portions of cells, which are essentially voids partially or wholly surrounded by glass walls, usually gassed when the glass is in its softened state. formed from the expansion of The presence of gas-filled or empty cells in a given volume of glass results in a lower centrifugal wet density compared to the same volume of solid glass. If the cell is closed and air is trapped, the perlite particles can float on the liquid. For example, breaking up perlite by milling can create an intricate cellular structure that retains its properties of low wet density and also provides useful characteristics for filtration and functional filler applications.
