Description
Technical field
The present invention relates to a kind of room temperature curing two-component polyurethane adhesives to stick agent, belongs to technical field of chemical adhesive, specifically
It is related to being adapted to the adhesive of steel substrate and cast polyurethane material room temperature.
Background technique
Two-component polyurethane adhesive sticks agent and is usually made of two components of first, second, is prepared by a certain percentage using preceding.First
Component (host agent) is component containing active hydrogen, and component B (curing agent) is the base polyurethane prepolymer for use as component containing-NCO group.Two-component
Adhesive for polyurethane category response type adhesive crosslinks after the mixing of two components and reacts and quickly form strong adhesive layer.
Have performance controllability, adhesive strength height, bonding range wide since two-component polyurethane adhesive sticks agent, can consolidate at room temperature
The advantages that change, can also be added catalyst appropriate or be heating and curing, and final adhesive strength is higher than One-component adhesive, has become
For kind in adhesive for polyurethane is most, the maximum product of yield.
Castor oil is in length fatty acids strand, and adhesive is often prepared with polyisocyanates, and the adhesive flexibility of preparation is good,
With preferable hydrolytic stability.However Li Houtang et al. (development of Li Houtang, Fan Li new polyurethane adhensives
With apply [J] China adhesive, 2005,14:35-36.) report adhesive bonding substrate surface be both needed to carry out blasting treatment,
Be not suitable for engineering construction application.It is more next to the performance requirement of adhesive recently as the development of the industries such as mining industry, communications and transportation
It is higher.Field of track traffic engineering construction is mostly to carry out outdoors, does not require nothing more than adhesive with preferable operative weldability, energy
Enough room temperature curings, and substrate adhesive in addition to grinder buffing without other physics and chemical treatment is required to have
There is higher adhesive strength.In addition, adhesive brushing is on substrate in substrate application Nian Jie with cast polyurethane material
Afterwards, it is desirable that adhesive surface carries out material casting after exposing for a long time in atmospheric environment again, and adhesive still shows good
Adhesive strength.
For sake of convenience, adhesive brushing after on substrate to the time of cast polyurethane material defined herein as bonding when
Between；It carries out with cast polyurethane material be bonded in adhesive brushing to substrate, is placed at room temperature for 72h and carries out bonding test, meet and draw
Bonding time of the adhesive strength more than or equal to 2MPa is stretched defined herein as the time can be bonded, and it is longer to be bonded the time, illustrates gluing
The process tolerance of agent is bigger.
The presently commercially available adhesive Nian Jie with cast polyurethane material applied to steel substrate, adhesive are brushed on substrate
Rapid failure is placed in atmospheric environment afterwards, adhesive strength declines rapidly, can be bonded the time less than 72h (tensile bond intensity is small
In 2MPa), it is not able to satisfy engineering field to adhesive strength, process tolerance requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide one kind can be bonded time long room temperature curing weatherable polyurethane gluing
Agent, the adhesive brushing is on substrate, and exposure in air, can still keep good bonding with cast polyurethane material for a long time
Property, and hot air aging, salt water resistance ageing properties are excellent.
In order to solve the above technical problems, the technical scheme is that one kind can be bonded time long room temperature curing weatherability
Adhesive for polyurethane is made of host agent component A and two component of curing agent B component, includes: in parts by mass
(1) host agent component A
(2) curing agent B component
Poly methylene poly phenyl poly isocyanate (PAPI) 32.3
Solvent 17.7
A/B=2/1.
The hydroxyl value of the hydroxyethylation bisphenol-A is generally 220~348mgKOH/g.
Applicable coupling agent such as 3- aminopropyl triethoxysilane (KH550), γ-glycidyl ether oxygen propyl trimethoxy
Silane (KH560), 3- methacrylic chloride oxygen propyl trimethoxy silicane (KH570), gamma-mercaptopropyltriethoxysilane
(KH580), γ-mercaptopropyl trimethoxysilane (KH590) or anilinomethyl triethoxysilane (ND-42) etc..
Applicable solvent such as ethyl acetate, butyl acetate, methylene chloride or acetone etc..
Applicable catalyst is one of catalyst such as common tin class, amine.
Other raw materials are kind and specification commonly used in the art.
Adhesive provided by the invention is suitble to polyurethane material be bonded under room temperature with steel, which can be bonded
Time be up to 72h, after brushing in atmospheric environment place 72h adhesive strength be still greater than 2MPa, in engineering construction to brushing after
The time tolerance being bonded is longer, and adhesive strength is high, and hot air aging, salt water resistance ageing properties are good, fit to environment
Ying Xingqiang, the application requirement being able to satisfy in engineering.
The present invention develops one kind and uses under room temperature, the glue Nian Jie with cast polyurethane material applied to steel substrate
Glutinous agent compensates for and places failure after prior art adhesive is brushed on substrate for a long time in atmospheric environment, adhesive strength decline,
Weatherability is poor, is not able to satisfy engineering field to the defect of high-adhesive-strength requirement.
