  • 与石油相比更环保

应用

金属加工

SOBAM 在金属加工中用作锻造润滑剂以替代锻造油,并作为淬火液替代淬火油。在这些应用中,ISOBAM 有助于提高生产安全性和产品质量,防止火灾危险和飞溅的火花。

含或不含石墨的油基模具润滑剂会在热锻造过程中由于产生大量烟雾而导致严重污染。 在锻造车间,油会泄漏并污染周围环境。

将基于 ISOBAM 的水溶性、无石墨热锻润滑剂与喷雾系统一起使用有许多优点,例如不污染环境、不沉淀颗粒或不凝结润滑剂,因为 ISOBAM 是水溶性的。此外,水溶性热锻润滑剂更环保,更适合工作环境。

特点和优点

  • 提高金属的可加工性

  • 防火花和防火
  • 防止腐蚀
  • 冷却改善钢的形态
  • 减少残留
  • 与油基润滑剂相比,烟雾和气味更少
  • 比油更安全,防火花和防火
  • 与油相比更健康

粘合剂

ISOBAM 的水溶液用于制备聚醋酸乙烯酯 (PVAC) 乳液作为保护胶体。水性 ISOBAM也可以作为粘合剂组分添加到乳液中。由于它的高耐热性和高粘性,ISOBAM 被用作为 PVA 基木材粘合剂的添加剂以改善刨花板的性能。

特点和优点

  • 提高薄膜刚性和强度

  • 提高粘合强度
  • 高初始粘性
  • 高粘合强度
  • 可交联以实现卓越的防水性

陶瓷粘合剂

在陶瓷生产中,各种添加剂和试剂被用作为干混料或浆液。粘合剂具有在切割和烧制之前获得压制或铸造部件的稳定生坯强度的功能。作为浆料中陶瓷粉末的水溶性粘合剂和分散剂,ISOBAM 可提高零件的生坯强度、孔隙率和密度。

 


ISOBAM 的类型有标准型,酰胺铵盐型和酰亚胺型。

标准类型的 ISOBAM 是中高分子量产品。利用其高硬度和高韧性等特点,可主要被用于黏合剂和乳液聚合稳定剂。

ISOBAM is an alkali water-soluble copolymer of isobutylene and maleic anhydride. The material, which has a white, powdery appearance, has outstanding properties that conventional water-soluble polymers such as polyvinyl alcohol and cellulose derivatives have not yet achieved. ISOBAM reacts with chemicals such as sodium hydrate, ammonia and amine and can be used as an aqueous solution.

An important field of application for ISOBAM is metal processing, where it is used as a forging lubricant and quenching fluid. With excellent water resistance and tackiness, it can also be used as an adhesive, in glass fibers, as a binder for ceramic powders and in other applications.


Features and benefits

  • Water-soluble polymer

  • Solvent-free
  • Non-Pigment Forging Lubricant (NPFL) additive
  • Excellent heat and water resistance
  • Environmentally friendly compared to oil

Applications

Metal processing

ISOBAM is used in metal processing as a forging lubricant to replace forging oils, and as a quenching fluid where it replaces quenching oils. In these applications, ISOBAM contributes to high production safety and product quality and prevents fire hazards and flying sparks.

Oil-based die lubricants with or without graphite cause severe contamination during hot forging as a result of heavy smoke generation. In forging shops, oil can leak out and contaminate the surroundings.

If, on the other hand, water-soluble, graphite-free hot forging lubricants based on ISOBAM are applied with a spray system, there are many advantages, such as no pollution of the environment, no settling of particles or no coagulation of the lubricant, since ISOBAM is water-soluble. In addition, water-soluble hot forging lubricants are more environmentally friendly and better for the working environment.

Features and benefits

  • Improves processability of metal

  • Spark and fire prevention
  • Prevents corrosion
  • Cooling improves steel morphology
  • Reduced residue
  • Less smoke and odor compared to oil-based lubricants
  • Safer than oil, sparking fire prevention
  • Health-friendly compared to oil

Adhesives

Aqueous solutions of ISOBAM are used to prepare polyvinyl acetate (PVAC) emulsions as protective colloids. Aqueous ISOBAM can also be added to the emulsion as an adhesive component. As a result of its high heat resistance and high tackiness, ISOBAM is used, for example, as an additive for PVA-based wood adhesives to improve the properties of chipboard.

Features and benefits

  • Improvement in film rigidity and strength
  • Improvement in bonding strength
  • High initial tack
  • High bonding strength
  • Can be cross-linked to achieve superior water resistance

Binder for ceramics

In the production of ceramics, various additives and agents are used as dry mixes or slurries. The binder has the function to obtain a stable green strength of the pressed or cast part before cutting and firing. As a water-soluble binder and dispersant for ceramic powder in the slurry, ISOBAM improves the green strength, porosity and density of the parts.


Features and benefits

  • Temporary binder and dispersants agent for ceramics

  • Excellent green strength and flexibility at low dosage
  • Enables better cutting, less scrap
  • Suited for low viscosity slurry with good storage stability
  • Water-soluble
  • Clean burn-out with low ash content
  • Improved compressive strength and flex strength

The types of ISOBAM include standard, amide ammonium salt, and imide.

The standard type of ISOBAM is used as a binder with excellent heat resistance and hardness. It is further characterized by an excellent dispersing effect, with high functionality of the carboxyl group in the molecule. Standard types have a molecular weight ranging from medium to high and are soluble only in alkaline solutions.
