Description

聚苯醚的发泡配方 Polyphenylene ether foam formulation

技术领域 FIELD

[0001] 本发明涉及一种发泡配方,特别是一种聚苯醚的发泡配方。 [0001] The present invention relates to a foam formulation, the foam formulation is especially polyphenylene ethers. 背景技术 Background technique

[0002] 聚苯醚(PPO)结构发泡成型工艺属于一种低压、化学、结构发泡成型工艺。 [0002] Polyphenylene oxide (PPO) belongs to a structural foam molding process a low pressure, chemical, structural foam molding process.

[0003] 在聚苯醚(PPO)结构发泡成型工艺中,通过对加入聚苯醚(PPO)塑料颗粒、发泡剂和白油按一定的配比,搅拌均勻,干燥,再进行注塑生产,使之分解释放出无毒、无腐蚀性、 不燃烧、对制品的成型及物理、化学性能无影响的气体而发泡,释放气体的速度可控制,发泡剂在塑料中有良好的分散性。 [0003] The polyphenylene oxide (PPO) structural foam molding process by (PPO) plastic particles, a blowing agent and a certain proportion of white oil, was added to stir the polyphenylene ether, dried, and then injection molding , so decomposition in non-toxic, non-corrosive, non-burning, molded and physical and chemical properties of the gas without the influence of the foamed article, the release rate of gas can be controlled, the blowing agent has a good dispersion in a plastic sex.

[0004] 聚苯醚(PPO)发泡塑料是以GE公司的聚苯醚(PPO)树脂为基体,其内部具有无数微小气孔的塑料,经过搅拌、注塑、发泡,形成气泡核,气泡核膨胀,泡沫遇冷模腔固化,得到塑料发泡聚苯醚(PPO)泡沫塑料,含有气体和固体两项。 [0004] The polyphenylene oxide (PPO) is a foamed plastic GE, polyphenylene oxide (PPO) resin matrix which includes an inner plastic innumerable fine pores, after mixing, injection molding, foaming, formation of cell nuclei, cell nuclei expanded, cured foam cold mold cavity, the plastic foam to give a polyphenylene oxide (PPO) foam, comprising two gas and solids. 其制品具有致密坚硬稳固表层,而内芯呈蜂窝状的结构,具有较高的强度比。 A solid article which has a dense hard surface layer and the inner core is a honeycomb structure having a high intensity ratio. 聚苯醚(PPO)结构发泡制品具有致密坚硬稳固表层,而内芯呈蜂窝状的结构,具有较高的强度比,是其同种未发泡制品的同单位重量、强度和刚度的3-4倍。 Polyphenylene oxide (PPO) having a structural foam article solid dense hard surface layer and the inner core is a honeycomb structure having a higher strength than, the same basis weight, strength and rigidity thereof isotype unfoamed article 3 -4 times. 这种结构能在需要增加硬度时增加零件壁厚,但重量不会随之增加。 This structure can increase the thickness of parts required when the hardness increases, but the weight is not increased. 聚苯醚的发泡工艺是采用化学结构发泡原理,添加了发泡剂后使塑料制品形成中间气孔从而达到提高强度,解决缩印的目的。 Foaming process is the use of a polyphenylene ether structure principle chemical foaming, a foaming agent is added to make the plastic article is formed so as to improve the strength of the intermediate hole, the purpose of solving microprinting. 目前一般采用GZ10030发泡剂或AC发泡剂进行发泡(发泡剂AC为偶氮二甲酰胺.生产厂家为江苏索普化工股份有限公司,发泡剂GZ10030生产厂家为VTC Silvergate A Division of VTC Ltd.,产品成份主要为偶氮二甲酰胺,载体为LDPE),而采用单独的GZ10030发泡剂配合聚苯醚(PPO)发泡,发泡比例多了容易产生大的气泡、分层发泡缺陷,导致喷漆后产品表面气泡,强度低,发泡剂比例少了产品产生缩印达不到应要的效果。 The general use GZ10030 blowing agent or foaming agent foaming AC (AC foaming agent is azodicarbonamide. Thorpe manufacturer Jiangsu Chemical Co., Ltd., manufacturers of blowing agent GZ10030 VTC Silvergate A Division of VTC Ltd., product ingredients mainly as azodicarbonamide, the carrier is LDPE), while the use of a separate foaming agent GZ10030 polyphenylene oxide (PPO) in foaming ratio more prone to large bubbles, delamination foaming defects which may cause bubbles on the surface after painting product, low strength, less foaming ratio of product to be produced to reach microprinting effect. 而采用单独AC发泡剂配合聚苯醚(PPO)发泡,模具表面析出溶于水的化学物质,黏附于模具表面,产品表面,影响产品表面质量,需要及时清理模具内异物,生产效率低。 The use of separate AC foam polyphenylene oxide (PPO) foaming mold deposited on the surface of water-soluble chemicals, adhesion to the mold surface, the surface of the product, affect the surface quality, need to clean up the foreign matter in the mold, low productivity .
