Biomass as an important part of green energy , by scientists from various countries and government attention . Due to its sustainable development as an important way to the use of biomass , traditional biomass carbonization , pyrolysis by widespread concern. By-product of the dry distillation carbonization process - wood tar contains a variety of inorganic and organic compounds , has a very strong harm to the environment , but also - valuable cheap chemical resources . How resource utilization of wood tar , is key to the development of raw material and dry distillation carbonization process . By simple distillation to obtain the wood tar in the 170-250 ° C fraction ; using GC-MS (GC-MS) components of this fraction were analyzed to determine the 37 kinds of compounds , which contain phenols, ketones , naphthyl class , they are an important chemical raw materials . Wherein the relative content of the phenolic compound was 40%, accounting for more than 11% of the overall wood tar . Substitution with the portion of wood tar phenol Synthesis of phenol resin adhesives , the use of triethylamine and barium hydroxide catalyst composite , formaldehyde method and simple procedures while using a vote heating , the amount of tar alternative synthesis process parameters , the reaction temperature , reaction time, catalyst content the orthogonalized studies to determine the optimum conditions obtained phenolic glue performance in line with GB / T 14074-2006 requirements , bonding strength is as high as 3.08MPa . This article will step feeding method , a simple procedure warming process is also used in traditional catalyst sodium hydroxide and oxygen hydroxide , also meet the requirements of GB / T 14074-2006 adhesive , sodium hydroxide catalyzed process, wood tar alternative the amount can reach 10%, the bonding strength of the resulting adhesive can be reached 1.77 MPa and 1.5 times higher than the national standard data , the curing time to meet the needs of industrial production ; for the potassium hydroxide catalyzed process , the amount of wood tar alternative reached 15 % , the adhesive bonding strength 2.07MPa, higher than 1.96 times the national standard , the curing speed also in line with the needs of the industrial production , its catalytic low viscosity than sodium hydroxide , is conducive to the storage of adhesives . This paper explores an effective way of using wood tar , and improve the traditional phenolic resin adhesive synthetic process , the resulting adhesives , low cost , high bonding strength , fast curing speed , low toxicity .
