一、目的和意义 苯酚甲醛树脂胶粘剂是国内外木材加工行业所用主要胶种之一。用酚醛胶所制人造板粘结强度好,其耐水、耐热、抗老化性能尤其突出,适于户外条件下长期使用。但是酚醛胶所用原料苯酚来自石油和煤焦化工,我国货源不够充分,其价格也较高,现工厂售价约为3300元/吨,因而使胶的价格也较贵,限制了它的广泛应用。 First, the purpose and significance Phenol formaldehyde resin adhesive is one of the main types of plastic used in the wood processing industry at home and abroad. Made of phenolic glue made of man-made board bonding strength, its water, heat, anti-aging performance is particularly prominent, suitable for long-term use under outdoor conditions. However, the phenol used as raw material phenol from petroleum and coal coke chemical industry, China’s supply is not sufficient, its price is higher, the factory price is about 3,300 yuan / ton, thus making the plastic price is more expensive, limiting its wide application .
