Abstract
The invention discloses a preparation method of a low free MDI monomer bicomponent solvent-free weight regulator, raising the temperature to 70-80 DEG C for reacting until hydroxy in a system reacts sufficiently; and adding a trimerization catalyst for carrying out trimerization reaction until the trimerization reaction is complete, ending the reaction to obtain the component B. The method has simple process and low production cost; the prepared polyurethane adhesive has low MDI monomer free amount, high curing speed, high solvent resistance and hydrolysis resistance and excellent property; and the component A and the component B in a solvent free adhesive do not contain the solvent, accord with the requirements on environment protection and energy saving, have good storage stability, and are beneficial to transportation and use.
Description
Technical field
The present invention relates to a kind of polyurethane adhesive, particularly a kind of low free MDI monomer double component solvent-free polyurethane adhesive.
Background technology
Along with the raising of country to environmental requirement, to limit gradually the quantity discharged of solvent, the usage quantity of solvent-based adhesive will gradually reduce.
Solvent-free compounding technology meets efficiently fully, environmental protection, requirements of saving energy, it has technical process simple, occupation area of equipment is little, raw material is economized, power consumption is few, and maintenance cost is low, production rate high-technology advantage, and no solvent residue in the composite product, can the safety in utilization of product not caused damage.The risk of its production process presence of fire etc. reduces greatly, and is safer.The two-pack solventless adhesive is to be coated with under solvent-free situation, is not subjected to the solvent discharge quantitative limitation, adapts to country to environmental protection requirement, more and more is subjected to insider's attention and application.
Diphenylmethanediisocyanate is abbreviated as MDI, and replacing TDI to prepare polyurethane curing agent with MDI is the hot subject of urethane industry research in recent years.Advantages such as this at first is because MDI compares with TDI, and it is big to have a molecular weight, and volatility is little, and smell is little, and toxicity is little had both satisfied the requirement of current social enviroment protection, also helped workers'health.Secondly, MDI compares with TDI, and price is much lower, helps saving cost, improves competitiveness of product, and the solidifying agent of producing with MDI has better mechanical property in addition.
At present, be that the method for feedstock production solidifying agent is with MDI and polyol blends reaction with MDI, generate base polyurethane prepolymer for use as.But in the MDI molecule, because the conjugated structure of aromatic ring influence, make the carbon atom cloud density on the NCO descend, demonstrate better Electron Affinities, the easier attack that is subjected to nucleophilic reagent so the NCO group has bigger reactive behavior, very easily causes the big and skewness of prepolymerization reaction molecular weight of product, viscosity is big, with problems such as host mutual solubility differences.For addressing this problem, generally the method for Cai Yonging is to make MDI excessive greatly, as to control NCO:OH be 10:1, even it is higher, and adopt SA macromolecule polyester polyol or polyether glycol and MDI prepolymerization reaction, the reaction product that obtains like this contains the MDI free monomer of high level, its free MDI monomer content is up to 5 ~ 10%, too much dimerization reaction can take place in free MDI monomer, the generation insolubles is separated out, make the product muddiness, small molecule monomer causes degradation under the binding property to interfacial migration.Therefore, should reduce the monomeric residual quantity of MDI in the preparation process as far as possible.
Free MDI monomer needs to be removed by the aftertreatment technology of complexity, as wiped film evaporator, and solvent-assisted distillation/condistillation, molecular sieve, solvent extraction etc.Existing MDI removal method, adopt the distillatory method to remove as the residual monomer of the patent (CN02105524.6) of U.S. gas chemicals company reaction, though also can prepare the base polyurethane prepolymer for use as of free MDI monomer mass percent less than 2.5% low free MDI monomer content.But the NCO mass percent has only 0.5 ~ 8% in this patent, and lower NCO content can cause sizing agent shortcomings such as curing speed is slow, viscosity is excessive, levelling property difference to occur in use.
Summary of the invention
The object of the present invention is to provide the preparation method of the solvent-free dual-component polyurethane adhesive of a kind of low free MDI monomer.
The technical solution used in the present invention is:
The preparation method of the solvent-free dual-component polyurethane adhesive of low free MDI monomer, comprise the preparation of A component end OH polyvalent alcohol and the preparation of B component end NCO base polyurethane prepolymer for use as, the A component is obtained by esterification by dibasic alcohol and long carbochain aliphatic dibasic acid and/or aromatic acid, the B component by MDI monomer, plant oil modified polyvalent alcohol and/or polyester polyol by NCO/OH=3～5.5:1(mol ratio) reaction make, the preparation of B component may further comprise the steps:
1) plant oil modified polyvalent alcohol, the first at the most pure content of water in system of polyester polyols dehydration of alcohols (mass percent) are lower than 0.05%, add MDI monomer, molecular weight regulator, being warming up to 70～80 ℃, to react to the system hydroxyl reaction complete;
2) add catalyst for trimerization continuation insulation and react, trimerization reaction is the back termination reaction fully, obtains the B component.
The preparation of A component may further comprise the steps:
1) dibasic alcohol is mixed with long carbochain aliphatic dibasic acid and/or aromatic acid, carries out esterification at 130～160 ℃, when the system aquifer yield reach the esterification theory go out water number 60～80% the time, be warming up to 200～220 ℃ and continue to react;
2) reduce to below the 15mgKOH/g when acid number, decompression esterification is to acid number＜1.0mgKOH/g, and cooling discharge obtains the A component.
