Принадлежит:

The invention discloses cold-resistant, solvent-resistant and yellowing-resistant polyurethane resin and a preparation method thereof. The cold-resistant, solvent-resistant and yellowing-resistant polyurethane resin is polymerized by main materials and auxiliary materials in a certain ratio under certain process conditions, wherein the main materials comprise diisocyanate, polyol compound, dihydric alcohol chain extender and diamine chain extender; and the auxiliary materials comprise catalyst, auxiliary agent, solvent and chain terminator. The preparation method comprises the following steps of: reacting active hydrogen in a low-activity hydrogen compound with diisocyanate group at the earlier stage, and then feeding the diamine chain extender into the reaction substances in batch to continually improve the molecular weight of macromolecular polyurethane resin so as to synthesize a polyurethane resin material with ultrahigh molecular weight. The solvent resistance of the polyurethane resin ...

Dry type polyurethane resin for pasting gold-silver film and preparation thereof

Номер: CN0101481453A
Автор: TANG TAO, ZONG JUNYE, TAO TANG, JUNYE ZONG
Принадлежит:

The invention discloses a dry polyurethane resin for sticking a gold/silver film and a method for preparing the same. The raw materials of the dry polyurethane resin contain: diisocyanate polyalcohol compound, coupling agent, micro molecular dibastic alcohol chain extender having a molecular weight of 62-200g/mol, catalyst, auxiliary agent and solvent. During the synthesis of the polyurethane resin, the soft segment and the hard segment in the polyurethane chain segment are reasonably separated by adopting a special synthesis process and the coupling agent is grafted in the polyurethane chain segment, such that, during the film forming, the resin synthesized has reduced surface tightness, the scratch resistance and the abrasion resistance are not obviously changed, and the resin is easy to combine with the gold/silver film. Besides, the grafted coupling agent promotes the combination of the polyurethane material and the gold/silver film. The dry polyurethane resin for sticking a gold/silver ...

Dry bonding layer polyurethane resin for pasting double mirror and preparation method thereof

Номер: CN0101870809B
Автор: HUI JIANQIANG, WU CHUNYU, ZONG JUNYE, JIANQIANG HUI, CHUNYU WU, JUNYE ZONG
Принадлежит:

The invention discloses a dry bonding layer polyurethane resin for pasting double mirror and a preparation method thereof. The formula of the resin mainly comprises raw materials including diisocyanate, a polyalcohol compound, a chain extender, an antioxidant, a catalyst, an aid and a solvent, wherein the raw materials are mixed in a certain ratio to undergo chemical reactions under a set condition so as to generate the polyurethane resin which meets a requirement. The dry bonding layer polyurethane resin for pasting the double mirror produced by the preparation method of the invention has the advantages of fully solving the problem that air bubbles at the bottom of a leather groove of conventional large pattern-pasted double mirror cannot be eliminated fully, improving resin transparencyand pattern definition and greatly lifting the grade of a double mirror synthetic leather.
