Abstract

The invention relates to a high-temperature resistant adhesive for a filter cleaner of an automobile. The adhesive comprises the following raw materials in percentage by weight: 13 to 16 percent of polyvinyl chloride (PVC) resin, 19 to 22 percent of dioctyl phthalate, 2 to 3 percent of epoxidized soybean oil, 55 to 60 percent of calcium carbonate, 0.2 to 1 percent of liquid calcium zinc heat stabilizer, 2 to 5 percent of thermosetting phenolic resin, 0.3 to 1 percent of antioxidant, 1 to 2 percent of thixotropic agent and 0 to 2 percent of white oil. In the high-temperature resistant adhesive, phenolic resin modified polyvinyl chloride is adopted, the thermosetting phenolic resin has high infiltration capacity, so the adhesive is diffused and infiltrated to the surface of a bonding material fully to promote Brownian movement to make polar groups or chain knots on two interfaces get close to each other; and when the distance between the adhesive and adherend molecules is between 5 and 10 angstroms, mutually-attractive force is formed among interface molecules, and the distance among the molecules is further shortened to the maximum stable state, so the adhesive force of the adhesive can be enhanced; and the phenolic resin has the characteristics of high heat resistance, flame retardance and the like, so that the high-temperature resistant performance of the adhesive and filter cleaner products is enhanced.

Description

A kind of high-temperature resistant adhesive for filter cleaner of automobile
Technical field:
The present invention relates to purifier and technical field of adhesive, refer in particular to a kind of high-temperature resistant adhesive for filter cleaner of automobile.
Background technology:
Machine oil, fuel oil, air filter are for filtering, to enter machine oil, fuel oil, the airborne mechanical impurity of engine; precision pair and the unlikely generation heel and toe wear of cylinder liner piston ring of protection engine crankshaft link work part, fuel oil injection system, make economic target, dynamic index, reliability and the discharge index of engine be able to normal (attached) part of important joining of bringing into play.Along with the progressively enforcement of Abgasgesetz, engine technology progress has proposed new higher requirement to purifier product, and this shows all the more purifier to the supporting importance of engine.The underproof product of filtration efficiency can not can cause the engine premature wear of motor vehicle by the harmful dust impurity of engine is carried out to effective filtering while using, and reduces work-ing life, and harm engine even leads to a disaster.
Cause that purifier is defective mainly contains two reasons: the one, for the manufacture of the poor quality of the main raw material(s) filter paper of purifier, aperture is excessive, became uneven, or the broken number of filter paper is very few, it is wide too small to roll over, can not play due filteration, or the intensity of filter paper is too low, after the air effect of certain flow, produce and break, filtering efficiency significantly reduces.The 2nd, the adhesion process in producing is not grasped, the own poor quality of tackiness agent especially, thus make can not keep sealed state that dust is flow through from gap between filter paper and end cap, be therefore badly in need of the tackiness agent that research and development are more durable, cohesive force is stronger.
On the other hand, according to automotive industry yearbook related data, show, within 2007, Chinese automobile is sold 879.15 ten thousand, and automobile volume of production and marketing in 2008 breaks through sale of automobile scale in 9,000,000,2010 and reaches 1,263 ten thousand.In the situation that automobile industry market scale grows at top speed, as the main supporting industry of automotive industry, the important opportunity of Chinese purifier industry faces.Along with the development of automotive industry, automobile sticks with glue agent and is all developing rapidly from kind to output.According to statistics, at present Domestic Automotive Industry sticks with glue agent and sealing agent Year's consumption 50,000 tons of left and right.Automobile industry is very high to the quality of tackiness agent, performance, security requirement, China's adhesive industry general universal in, supply exceed demand for low grade products, Market competition, and the environment-friendly type that China is in great demand, high-quality, high-performance and special adhesive product, due to technology content and specification of quality high, need be from external a large amount of imports.The Qi Jie world tackiness agent conference of holding in Beijing is by environmentally friendly tackiness agent, formulation of exploitation, application and the standard for new product of high-quality, high-performance adhesive etc. is inquired into as an important subject under discussion, and predicts that high-performance environment protection type tackiness agent will become " new lover " of Market of Adhesives.
Therefore, develop high-quality, high-performance, functionalization, special typeization " green " environment-friendly adhesive product, comply with market new demand, seize tackiness agent high-end market, change the present situation of a large amount of imports of the high-grade glue of China, promote China comparatively to fall behind the development of adhesives industries, it is the extremely urgent task of domestic adhesive producing producer and R&D institution, be devoted to develop high quality, high-performance adhesive, meet automotive industry required, be also expected to obtain the return of great number.
Summary of the invention:
Main purpose of the present invention is to overcome the above-mentioned weak point of tackiness agent for existing purifier, and a kind of high-temperature resistant adhesive for filter cleaner of automobile is provided, and to improve bonding process and bond quality in purifier process for processing, improves the quality of purifier.
The present invention realizes the technical scheme that above-mentioned purpose adopts: a kind of high-temperature resistant adhesive for filter cleaner of automobile, in described tackiness agent, each material component and the mass percent that accounts for gross weight thereof are respectively: polyvinyl chloride resin 13%~16%, dioctyl phthalate (DOP) 19%~22%, epoxy soybean oil 2%~3%, calcium carbonate 55%~60%, liquid calcium zinc heat stabilizer 0.2%~1%, heat-reactive phenolic resin 2%~5%, oxidation inhibitor 0.3%~1%, thixotropic agent 1%~2%, white oil 0~2%.
In technique scheme, described oxidation inhibitor is antioxidant 1010, and its chemical name is: four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic ester] pentaerythritol ester.
Described thixotropic agent is aerosil, and it adds in resin, can make resin adhesive liquid when static, have higher denseness, becomes again under external force the material of low denseness fluid.
The preparation method of tackiness agent of the present invention is: by proportioning, each component is uniformly mixed and with three-roll grinder, is ground to certain fineness afterwards.
The present invention adopts phenolic resin modified polyvinyl chloride, because heat-reactive phenolic resin has very strong wetting capacity, can make binding agent fully spread and infiltrate adhesive surface, promote pedesis, make polar group or the chain link at two interfaces mutually close, research shows, when tackiness agent and the intermolecular distance of adherend reach 5 dust~10 dust, between the molecule of interface, just produce the power that attracts each other, intermolecular distance is further shortened in maximum stable state, therefore can play the effect that strengthens binding agent cohesive force; And resol has the features such as thermotolerance is strong and fire-retardant, the resistance to elevated temperatures of tackiness agent and purifier goods is strengthened.
Tackiness agent of the present invention is not only applicable to purifier to be used, and the bonding that also can be used as the materials such as metal, plastics, rubber, glass, pottery is compound.
