Chemical properties and mechanism of A-300 catalyst

A-300 catalyst is a highly efficient polyurethane catalyst based on organometallic compounds, with its main component being bis(dimethylamino)acetate. This catalyst accelerates the formation of polyurethane by promoting the reaction between isocyanate and polyol. Compared with conventional catalysts, A-300 catalysts have higher catalytic efficiency and selectivity, enabling rapid reactions at lower temperatures, reducing energy consumption and production time.

1. Chemical structure and properties

The chemical structure of the A-300 catalyst is shown in formula (1):

[ text{Zn(OOCCH_2N(CH_3)_2)_2} ]

The compound consists of zinc ions (Zn²⁺) and two dimethylamino ethyl roots (OOCCH₂N(CH₃)₂⁻), forming a stable hexa-coordinate structure. This structure imparts excellent thermal and chemical stability to the A-300 catalyst, allowing it to maintain efficient catalytic activity over a wide temperature range.

2. Mechanism of action

The mechanism of action of A-300 catalyst is mainly reflected in the following aspects:

  • Accelerate the reaction between isocyanate and polyol: The A-300 catalyst reduces the activation energy of the reaction by coordinating with nitrogen atoms in isocyanate molecules, thereby accelerating the heterogeneity Addition reaction between cyanate and polyol. This process not only increases the reaction rate, but also reduces the generation of by-products, ensuring the purity and quality of the polyurethane product.

  • Controlling Crosslinking Density: The A-300 catalyst can accurately regulate the crosslinking density of the polyurethane molecular chain, thereby affecting the mechanical properties of the final product. By adjusting the amount of catalyst, the hardness, elasticity and durability of polyurethane materials can be controlled to meet the needs of different furniture manufacturing.

The A-300 catalyst has high selectivity, which can promote the main reaction while inhibiting the occurrence of side reactions and ensuring the stability of product quality.

3. Environmental protection and safety

The environmental protection of A-300 catalyst is one of its highlights. Unlike other traditional catalysts containing heavy metals or harmful substances, the zinc in the A-300 catalyst is relatively friendly to the human body and the environment and complies with the EU REACH regulations and the US EPA standards. In addition, the A-300 catalyst does not produce volatile organic compounds (VOCs) during use, reducing air pollution and meeting the requirements of modern furniture manufacturing for green production.

Foam molding is one of the common applications of polyurethane materials in furniture manufacturing, and is mainly used to make fillings for soft furniture such as sofas, mattresses, cushions. In traditional foam forming processes, the choice of catalyst is crucial because it directly affects the foaming speed, density and uniformity of the foam.

The application of A-300 catalyst in foam molding has the following advantages:

  • Fast foam: The A-300 catalyst can significantly shorten the foaming time and can usually complete the foaming process within 30 seconds. This not only improves production efficiency, but also reduces the mold occupancy time and reduces production costs.

  • Uniform foaming: Because the A-300 catalyst has high selectivity, it can effectively avoid side reactions, so the bubble distribution is more uniform during the foaming process, and the density and elasticity of the foam material are More consistent. This is crucial to improving the comfort and durability of furniture.

  • Environmentality: The A-300 catalyst does not contain volatile organic compounds (VOCs), which meets the environmental protection requirements of modern furniture manufacturing. Foam materials produced using A-300 catalyst have low odor and toxicity and are suitable for use in home environments.

2. Adhesive preparation

Polyurethane adhesives are widely used in wood splicing, leather bonding and other processes in furniture manufacturing. Traditional polyurethane adhesives take a long time during the curing process and are easily affected by environmental humidity, resulting in unstable adhesion effect. The application of A-300 catalyst can effectively solve these problems.

  • Rapid Curing: The A-300 catalyst can significantly speed up the curing speed of polyurethane adhesives, and the curing process can usually be completed within 10-15 minutes. This not only improves production efficiency, but also reduces the waiting time of workpieces and improves the overall operating efficiency of the production line.

  • High-strength adhesion: The A-300 catalyst can promote the cross-linking reaction of polyurethane molecular chains and enhance the adhesion of the adhesive. Adhesives treated with A-300 catalyst have higher tensile strength and shear strength, which can effectively prevent furniture from cracking or falling off during use.

  • Weather Resistance: The polyurethane adhesive prepared by the A-300 catalyst has excellent weather resistance and can maintain good bonding effect in harsh environments such as high temperature and humidity. This is especially important for the manufacturing of outdoor furniture.

Polyurethane coatings are widely used in the protection and decoration of furniture surfaces, and can give furniture excellent performance such as wear resistance, scratch resistance, corrosion resistance, etc. Traditional polyurethane coatings require higher temperatures and longer time during the curing process, and are prone to quality problems such as sagging and blistering. The application of A-300 catalysts can significantly improve these situations.

  • Rapid Drying: The A-300 catalyst can accelerate the drying process of polyurethane coatings and can usually cure within 1-2 hours. This not only improves production efficiency, but also reduces the sagging phenomenon of the paint, ensuring the flatness and aesthetics of the furniture surface.

  • Excellent adhesion: The A-300 catalyst can promote chemical bonding between polyurethane coating and substrate and enhance the adhesion of the coating. The coating processed by A-300 catalyst has better anti-flaking properties and can effectively prevent the surface coating of furniture.

  • Environmentality: The polyurethane coating prepared by A-300 catalyst does not contain volatile organic compounds (VOCs), which meets the environmental protection requirements of modern furniture manufacturing. Paints produced using A-300 catalyst have low odor and toxicity and are suitable for use in home environments.
