The coating of the thermosetting pare polyester powder is a kind of decorative and ant icorrosive coating/materials. It is a new member of the large family of coating powders. This paper describes the method of making the polyester rasirt, the selection of hardener, hardening mechanism and the powdering process to make the polyester coating powder. The coating of the pure polyester powder is cheap and shows vary good property So that it can be widely used. The social and economical interests will be high from...

The coating of the thermosetting pare polyester powder is a kind of decorative and ant icorrosive coating/materials. It is a new member of the large family of coating powders. This paper describes the method of making the polyester rasirt, the selection of hardener, hardening mechanism and the powdering process to make the polyester coating powder. The coating of the pure polyester powder is cheap and shows vary good property So that it can be widely used. The social and economical interests will be high from the development and production of this kind coating whose applicability and feasibility are also pointed out in the present paper.

纯聚酯粉末涂料是集装饰性和防腐性为一体的粉末涂料大家族中的新成员,本文阐述了聚酯树脂的制备,固化剂的选择及固化机理和聚酯粉末涂料的制粉工艺等内容,纯聚酯粉末涂料成本低廉,性能优良,应用广泛.积极地开发研制和生产纯聚酯粉末涂料,将会产生较深远的社会影响和经济效益.本文注意了成果的应用性和现实的可行性

A study on kinetics of solid state ploycondensation of two kinds of copolyesters copolymers of polyethylene terephthalate is carried out.One copolycondensation monomer is isophthalic acid and the other adipic acid.The kinetics are conformarity with second-order reaction equation,the reaction rate constant value(k) and reaction energy(Ea) are obtained.It is shown,that the reaction rate on solid state polycondensation of copolyesters is obviously faster than pure polyester(PET).

对两种共聚酯作了固相聚合动力学研究,其动力学符合二级反应方程。求出了反应速度常数k和活化能En。结果表明,共聚酯固相聚合反应速度明显快于纯聚酯

The polyether-ester polyurethane cellular elastomer sole was prepared using water as blowing agent.The result showed that its mechanical properties was satisfactory for the sole,and its cost was lower 10%~15% than that of polyester polyurethane.The formula(phr)by orthogonalization was polyether 60,polyester 40,MDI 42,liquid MDI 7,chain extender 8,catalyst 0.6,foam homogenizing agent 0.7, and water 0.06.

将聚醚多元醇和聚酯多元醇的混合,以水为发泡剂,三乙烯二胺和辛酸亚锡的复合物为催化剂,1,4-丁二醇为扩链剂,聚硅氧烷为匀泡剂,可制备聚(醚-酯)型聚氨酯微孔鞋底材料,其物理机械性能优于GB10508—89指标,成本比纯聚酯型聚氨酯的低10%~15%。用正交试验确定的最优配方(质量份)为:聚醚多元醇60,聚酯多元醇40,MDI42,液化MDI7,扩链剂8,催化剂0.6,匀泡剂0.7,水0.06。
