Abstract
The application discloses a special emulsion type phenolic resin for automobile filter paper and a synthesis process thereof, wherein the synthesis process comprises the following steps: carrying out polymerization reaction on raw materials of phenol and aldehyde under the action of an alkaline catalyst to obtain matrix phenolic resin; and carrying out an emulsion reaction on the obtained matrix phenolic resin and the composite emulsion in the presence of a protective colloid solution to obtain the emulsion type phenolic resin. Based on the current situation and the future trend of the automobile filter paper industry, the emulsion type phenolic resin is synthesized by adopting the polymerization and emulsification step-by-step double processes on the basis of the traditional phenolic resin synthesis process, and the stability of the special aqueous emulsion type phenolic resin product for the automobile filter paper is obviously improved.

Background
The automotive industry is one of the largest, most important industries in the world. In a sense, the development level of the automotive industry reflects the comprehensive national strength of a country. The mass production and sales of Chinese automobiles in 2016 are more than 2,800 thousands of automobiles (data source: China automobile industry Association), and the automobile mass production and sales continuously live at the first position of the world for many years. As the China has huge automobile consumption demands and has obvious resource cost advantages, automobile manufacturers in Europe, America and Japan and Korean are also spread in domestic markets. The global whole vehicle capacity is transferred and centralized to China, the development of the automobile part industry in China is promoted, large-scale transnational part suppliers accelerate the pace of building joint ventures or sole-eared companies in China, advanced production technologies and management modes are brought into the domestic market, and good opportunities are provided for the development of domestic enterprises. The increase of the automobile holding amount, the increase of the whole automobile yield, the transfer of global purchasing to China and the like all bring rare development opportunities for the development of the automobile industry in China. And automobile parts can enter a fast development peak period after the high-speed development of the whole automobile industry.
The filter is used as a very important component of an automobile engine, and the automobile filter paper is one of main materials for producing the automobile filter, namely, the automobile filter paper, namely air filter paper, engine oil filter paper and fuel filter paper. The filter is made of resin-impregnated base paper through the processes of partial pressure, wave pressing, wave receiving, curing and the like on a filter production line. The filter paper used as the filter medium of the filter plays a decisive role in the performance of the filter, namely the "lung" of the engine. The automobile engine is provided with an air filter, an oil filter and a fuel filter which can respectively and effectively filter hard impurities, corrosive particles, trace cutting scraps in the engine oil, oxidized decayed sludge of the engine oil, colloid and the like in the air entering the automobile engine, so that the dust-containing air is purified, the engine oil of the engine is kept clean, dust and trace water drops are prevented from being mixed into the fuel, the engine is prevented from being abraded, the engine runs safely, and the service life of the engine is prolonged.
The filter paper base paper is loose in paper, soft in texture and low in inherent strength, and cannot withstand the severe processing process of filter element production. But also can not meet the performance requirements (such as chemical resistance, solvent resistance, pressure resistance and the like) of the filter element in the using process. Therefore, the base paper of the filter paper needs to be impregnated and reinforced by resin impregnation liquid, so that the filter paper has excellent processing performance, the process requirement of filter element production is met, and meanwhile, the good service performance (such as chemical resistance, solvent resistance, pressure resistance and the like) of the filter element in the use process is ensured.
Currently, impregnating resins for automobile filter paper mainly include non-curable resins (emulsions such as styrene-acrylic and vinyl acetate) and curable resins (phenolic resins):
one, non-curing resin
The non-curable resin is mainly styrene-acrylic emulsion and styrene-butadiene emulsion. The base paper treated by the resin impregnation has the advantage of good toughness. The main problems existing in the method are as follows: although the filter paper dipped by the resin has good toughness, the filter paper has low bursting strength and stiffness, and poor chemical resistance, solvent resistance and pressure resistance, and can only be applied to medium and low grade filter elements.
Two, cured phenolic resin
Alcohol-soluble phenol resin:
the application of the alcohol-soluble phenolic resin in the production of the automobile filter paper has been over 40 years, the technology is mature, and the filter paper subjected to impregnation treatment has the advantages of high stiffness and high chemical resistance. The main problems existing in the method are as follows: the filter paper impregnated with the alcohol-soluble phenol resin has good chemical resistance and high stiffness, but lacks flexibility and is brittle. Is easy to break during the rolling operation; meanwhile, a large amount of organic solvent is consumed for preparing the alcohol-soluble phenolic resin impregnation liquid, and serious environmental pollution, flammable potential safety hazards, explosive potential safety hazards and the like exist, so that a lot of adverse factors exist in the application process of the alcohol-soluble phenolic resin.
(II) water-soluble phenolic resin:
the base paper treated by the water-soluble phenolic resin impregnation has the advantages that no organic solvent is needed in the preparation process of the base paper impregnation liquid, no environmental pollution is caused, and no potential safety hazards such as flammability, explosiveness and the like exist. The main problems existing in the method are as follows: although the filter paper impregnated with the water-soluble phenol resin has high stiffness, it is very fragile. Is very easy to break during the rolling operation. Therefore, the emulsion can not be used alone, and can only be used together with non-curable resins such as styrene-acrylic emulsion, styrene-butadiene emulsion and the like. Meanwhile, the resin has high water solubility, so the requirements on production equipment and technology are high; during transport and storage, low temperature processing is required. So that the method has great quality risk in preparation, storage and transportation and application links. For the reasons, research and development of novel impregnating resin for automobile filter paper are continuously carried out at home and abroad.

The filter paper impregnated by the emulsion type phenolic resin has the advantages of high stiffness and good toughness of a filter element, and simultaneously has high chemical resistance and solvent resistance, and can completely replace the traditional alcohol-soluble phenolic resin; in addition, in the preparation process of the base paper impregnation liquid, water is used as a solvent, the resin has good dispersibility, no organic solvent is used at all, no environmental pollution is caused, and potential safety hazards such as flammability, explosiveness and the like do not exist.
