在塑料装饰材料中常用的树脂种类有:
The types of resins commonly used in plastic decoration materials are:
聚乙烯(PE)、聚氯乙烯(PVC)、聚苯乙烯(PS)、酚醛(PF)、脲醛(UF)、环氧(EP)、聚酯(PR)、聚氨酯(PU)、聚甲基丙烯酸甲酯(PUMA)、有机硅(SI)等。
Polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), phenolic aldehyde (PF), urea formaldehyde (UF), epoxy (EP), polyester (PR), polyurethane (PU), polymethyl methacrylate (PUMA), silicone (SI), etc.
按照受热时所发生的变化不同,合成树脂又可分为热塑性树脂和热固性树脂两种。
Synthetic resins can be divided into thermoplastic resins and thermosetting resins according to their changes when heated.
热塑性树脂
Thermoplastic resin
是具有受热软化、冷却硬化的性能,而且不起化学反应,无论加热和冷却重复进行多少次,均能保持这种性能。凡具有热塑性树脂其分子结构都属线型。它包括含全部聚合树脂和部分缩合树脂。热塑性树脂有:聚乙烯、聚氯乙烯、聚苯乙烯、聚酰胺、聚甲醛、聚碳酸酯、聚苯醚、聚砜、橡胶等。热塑性树脂的优点是加工成型简便,具有较高的机械能。缺点是耐热性和刚性较差。
It has the properties of heating softening, cooling hardening, and no chemical reaction, no matter how many times heating and cooling repeated, can maintain this performance. All thermoplastic resins are linear in their molecular structure. It contains all polymerized resins and partially condensed resins. Thermoplastic resins are: polyethylene, PVC, polystyrene, polyamide, polyformaldehyde, polycarbonate, polyphenylene ether, polysulfone, rubber and so on. The advantage of thermoplastic resin is simple processing and high mechanical energy. The disadvantage is poor heat resistance and rigidity.
热固性树脂
Thermosetting resin
树脂加热后产生化学变化,逐渐硬化成液压钢坝  型,再受热也不软化,也不能溶解。热固性树脂其分子结构为体型,它包括大部分的缩合树脂,热固性树脂的优点是耐热性高,受压不易变形。其缺点是机械性能较差。热固性树脂有酚醛、环氧、氨基、不饱和聚酯以及硅醚树脂等。
After heating, the resin changes chemically, and then gradually hardens and forms. Then the heat is neither softened nor dissolved. The molecular structure of thermosetting resin is somatotype, which includes most of condensation resin. The advantages of thermosetting resin are high heat resistance and not easy to deform under pressure. The drawback is poor mechanical properties. Thermosetting resins include phenolic, epoxy, amino, unsaturated polyester and silicone resins
