树枝状分子清漆组合物在汽车涂装领域的良好应用

用于汽车涂装的清漆优选具有良好的视觉性能材料,为了改善环境相容性,还期望材料具有低溶剂含量,即固含较高。但是,提高清漆的固含,由于漆料的粘度增大,通常会使视觉性能变差。一种高度官能化的粘结剂的清漆组树枝状聚合物适用于制备具有高固含和良好表面外观的涂料组合物。低的羟基官能度的聚酯会得到软的薄膜,高羟值聚酯可得到硬的薄膜,采用树状分子得到的清漆组合物具有良好的表观,且固含普遍高于现有材料(50%)。最新第四代高分子材料-高性价比树枝状聚合物材料的专业制造商—威海晨源分子新材料有限公司

Magnetic dendritic heavy metal removal agent has excellent performance.

Magnetic dendritic heavy metal removal agent has excellent performance.

Heavy metal ions can be adsorbed and encapsulated by dendrimers with lots of hydroxyl groups, includes Ag+, Cu2+, Zn2+, Fe2+, thus dendrimers or dendritic polymer products can be used to remove heavy metal ions. Magnetic particles and amino terminated particles have good removal ability of heavy metals, if modified by dendrimer, the treat effect will be more excellent. Magnetic water treatment agents with different generations can be adjusted according to pH of various systems.

Effective application of dendrimers in the field of ultra-low pressure reverse osmosis membrane.

Effective application of dendrimers in the field of ultra-low pressure reverse osmosis membrane.

Dendrimer-based ultra-low pressure reverse osmosis membrane can effectively retain a variety of salts, such as sodium sulfate, sodium chloride, magnesium sulfate, retention rate reaches 92%, in particular sodium sulphate, up to 98%. The membrane has high flux, and low operating pressure. Water flux can reach 30-40 L • M-2 • h – 1, operating pressure was 0.6MPa. The film has good resistance to chlorine, acid and alkali resistance is little weaker. In addition, the membrane has excellent separation performance for PEG-200, showing its promising application in separation small organic molecules from the water.

Carboxyl terminated dendrimer based aluminum tanning agent without chrome.

Carboxyl terminated dendrimer based aluminum tanning agent without chrome.

As people’s awareness of environmental protection, negative effects of chrome tanning can’t be ignored any more, therefore, the production of little chrome, no chrome tanning agents is more important for industry. Carboxyl terminated dendritic tanning agents overcome aluminum tanning agent disadvantages that not washable, low shrinkage temperature, and have great retanning effect, is a new kind of multi-tanning agent. Dendritic polymers have hyperbranched structures and lots of end groups, can form crosslinks with aluminum and dermomyotome with retanning effect, increasing thick rate was increased by 25.10% than ordinary aluminum tanning agent. While the leather tear strength was improved 12.69% and tensile strength 11.28%, and the specific performance of tanning agents can effectively disperse the fiber bundle, so that leather surface was full soft.

Effective application of dendritic polymers in protective substrates.

Effective application of dendritic polymers in protective substrates.

In order to prevent metal pipe, pipe connections and pipelines from corroding, mechanical damage caused by friction or degradation due to exposure to the sun, soil, moisture etc, protective coating can be coated. Dendrimer based curable compound is particularly good at providing anti-cathode degumming performance, thus protecting the pipes. When it’s not cured, provides excellent adhesion to substrates.

Application of dendritic demulsifer in oil field.

Application of dendritic demulsifer in oil field.

Dendrimer based new demulsifer has good surface properties and infiltrability, it can quickly reach oil-water interface to replace active substances to form new film; due to special structure of dendritic polymers, molecules of the newly formed films are difficult to approach each other, and weaken Waals forces to lower film strength and promote separation of water and oil.

Dendritic acrylic polyurethane nanocomposite has good performance in coating application.

Dendritic acrylic polyurethane nanocomposite has good performance in coating application.

Mechanical properties, water resistance, solvent resistance of nanocomposite is not ideal due to small functionality of the preparation material conventional linear acrylic polyurethane. Dendritic polymer was used to prepare high functionality acrylic polyurethane systems, obtained acrylic polyurethane/inorganic nanocomposite with high performance, the adhesion reached 0 class, which was enhanced 4 classes than conventional systems, the hardness improved from 2B to 4H, and flexibility was greatly increased, meanwhile, the dendrimer based coating has double bond.

Dosage of inorganic oxide was 1% -5%, added 1 wt% photoinitiator named Runtecure 1103, mixed 15 min without light, coated on glass, dried at 50 ℃ in vacuo, and irradiated with UV light to obtain films. The new film has following properties: gloss, adhesion, hardness, anti-stoning, flexibility, weather resistance, solvent resistance, chemical resistance.
