THYOSIL MBL3025

ACRYLIC CARRIER FOR LIQUID MASTERBATCH 液體色母料載體 丙烯酸樹脂

Description描述
A liquid master batch is a custom blend of additives and pigments dispersed in a liquid vehicle chosen in order to ensure compatibility with the end-use polymer.

THYOSIL MBL3025 is a high efficiency acrylic fluid that provides flow with flexibility and can be used with a variety of plastics

Existing liquid color concentrate technology uses carrier systems that are base on surfactants, oils and/or plasticizers. This products are often incompatible with many polymers resulting in loss of physical properties, processing problems like screw slippage. Many of the existing carriers affect the clarity of optically clear polymers, such as polycarbonate (PC), polymethyl methacrylate (PMMA), styrene-acrylonitrile (SAN). Therefore, liquid color concentrates are not used with these plastic resins. Also existing color concentrate carriers have limited heat stability and used to color polymers, such as PC, which is processed at about 315 °C.

Currently, pellets-based concentrates, and pre-colored resins are used. But such uses also present problems. Pellets-based concentrates for tint applications have be used at high dilution or letdown ratios to achieve good color distribution. Pre-colored resins are expensive to manufacture and warehouse. Such resins also undergo two heat histories (initial compounding and subsequent molding), which can be detrimental to some polymers.

THYOSIL MBL3025 is an acrylic fluid that achieves the problems mentioned before and it may be use with acrylonitrile-butadiene-styrene (ABS), polyvinyl chloride (PVC), polybutylene terephthalate (PBT), Polycarbonate (PC), polymethyl methacrylate (PMMA), styrene-acrylonitrile (SAN), polyphenylene ether (PPE), styrene-butadiene-styrene (SBS), and acrylics polymers.

液體色母料是由載體，添加劑，顏料分散于液體載體的聚集體，此聚集體要與最終使用的聚合物的相容性好。THYOSIL MBL3025 一款高效率的丙烯酸流體提供流動(dòng)與柔韌性，并且與各種塑料相容性好。

現(xiàn)有的液體色母料技術(shù)采用了基于表面活性劑，油和/或增塑劑的載體系統(tǒng)。這種產(chǎn)品往往是許多聚合物不兼容導(dǎo)致的物理性能損失，及加工問題，像螺絲滑絲。

許多現(xiàn)有載體影響光學(xué)透明的聚合物，例如聚碳酸酯（PC），聚甲基丙烯酸甲酯（PMMA），苯乙烯 - 丙烯腈（SAN）的清晰度。因此，這種液體色母料不能用于這些塑料樹脂。

另外，現(xiàn)有色母料載體只有有限的熱穩(wěn)定性，并用于有色聚合物，如聚碳酸樹脂PC，處理溫度要達(dá)到約315℃ 。

目前使用的是粒狀為基礎(chǔ)的色母料，和預(yù)著色樹脂。但是還會(huì)出現(xiàn)這樣的問題。粒狀色母用于上色（著色）需要高稀釋或損失顏色的分散。而預(yù)著色樹脂會(huì)有很高的生產(chǎn)和存儲(chǔ)成本。而這種樹脂也經(jīng)受兩個(gè)加熱階段（初始混合和隨后的模制），這可能不利于某些聚合物。

THYOSIL MBL3025 做為一款丙烯酸流體載體，可以解決上述的缺陷和不足?？梢赃m用于 丙烯腈 - 丁二烯 - 苯乙烯（ABS），聚氯乙烯（PVC），聚丁烯對(duì)苯二甲酸酯（PBT），聚碳酸酯（PC），聚甲基丙烯酸甲酯（PMMA），苯乙烯 - 丙烯腈（SAN），聚苯醚（PPE），苯乙烯 - 丁二烯 - 苯乙烯（SBS），和丙烯酸聚合物 .

Color development 展色性

Achievement of a color match of a plaque with a desired color from the creativity of a designer or a pre-arranged color standard such as Pantone R color standards from an inventory of commercially available colorant is relatively straightforward for a skilled color matcher, even if a few iterations are required to satisfy the customer.

The concentration of colorant into a carrier is significant because of the relative cost of the colorant ingredient (s) and the need for that color to consistently and precisely mix and disperse into the carrier.  It should consistently and precisely dilute into the plastic resin and other compound ingredients during letdown of the concentrate in mixing equipment prior to formation of the pre-form embryonic bottles or other articles. Letdown ratios depend on the concentration of colorant in the color concentrate and whether the final molded product is intended to be opaque, translucent or transparent. Due to liquid master batches easy incorporation into the polymer matrix they are an excellent choice when it comes to transparent or translucent colors

Concentration of concentrate after letdown into the final molded product can range from about 0.1 to about 0.5 weigh percent.  The mixing equipment used to make the liquid color concentrate can be any suitable equipment already used in the art of making liquid color. For example such equipment includes high speed Cowles type dispersors, media mills, three roll mills and rotor stator type dispersors.The mixing equipment can operate at mixing speeds ranging from about 1000 rpm to about 2500 rpm and temperatures ranging from about 40°c to 80°C.

Surfactants are sometimes desired to aid in dispersion of dyes and pigment. THYON T34 is recommended.Also, functional additives for polyester bottles are added. They can include anti-oxidants, antistatics, acetaldehyde scavengers, blowing agents, biocides, exfoliated Nano-clays and the like.

調(diào)色可以參照潘通R色標(biāo)準(zhǔn) ，簡(jiǎn)單。著色劑在載體里的的含量可以精準(zhǔn)混合，相對(duì)成本優(yōu)勢(shì)顯著。它可以用于瓶胚或其它預(yù)混高濃縮塑料里，當(dāng)在稀釋時(shí)可以均勻隨著塑料的分散開。

它應(yīng)該在形成預(yù)制胚胎瓶或其它物品之前混合設(shè)備的濃縮物，期間一致且精確地稀釋到塑料樹脂和其它化合物成分。稀釋比率取決于著色劑在色母料中的濃度，以及是否最終成形的不透明的，半透明的或透明的。用液體母料容易引入聚合物基質(zhì)這是一個(gè)很好的選擇，用于透明或半透明色

最終模制產(chǎn)品后的濃縮濃度范圍可以為約0.1至約0.5的重量百分比。用于使液體色母料的混合設(shè)備可以是本領(lǐng)域制備液體顏色的在已使用的任何合適的設(shè)備。例如，這種設(shè)備包括高速考爾斯型分散機(jī)，介質(zhì)研磨機(jī)，三輥研磨機(jī)，轉(zhuǎn)子定子型分配器?；旌显O(shè)備可以在混合速度范圍從約1000rpm至約2500rpm和溫度范圍從約40℃至80℃進(jìn)行操作。

在分散染料和顏料時(shí)有時(shí)會(huì)用到表面活性劑，以幫助色料的分散。這里推薦用THYON T25。此外，可以添加一些功能性添加劑用于聚酯瓶。它們可以包括抗氧化劑，抗靜電劑，乙醛清除劑，發(fā)泡劑，殺菌劑，剝離納米高嶺土和類似物。
