Description
Technical field
The invention belongs to technical field of adhesive, be related to adhesive more particularly to a kind of bicomponent environment-friendly type adhesive and
Its preparation process.
Background technique
Wooden building materials are as the most important components in domestic market of building materials for home decoration, always by the blueness of the majority of consumers
It looks at, such as timber floor, wood furniture, wooden cabinet, wardrobe.In most wooden building materials, adhesive is as such product
Important auxiliary agent in production process, always by outer of interest in the industry.
Since formaldehyde has good stationarity, woodwork group fiber can be made to knit, and contraction is smaller, damages less, saves inherently
Physical capacity is strong；Uniform, penetration power is strong, can enhance tissue elasticity etc. is fixed, important work is played to the stability for improving adhesive
With becoming the important constituent of adhesive.At present on the market used in 70% or more adhesive all can release formaldehyde, thus
Influence environmental quality and consumer health.Woodwork in use, with the extension of time, constantly releasing free first
Aldehyde when building up to a certain amount of, can cause human body potentially to injure, and not environmentally.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to a kind of open formaldehydeless pair
Component polyurethane adhesive.
A kind of bicomponent environment-friendly type adhesive is mixed by component A and component B according to mass ratio 1:0.9~1.4, excellent
Mass ratio 1:1.2 is selected,
Component A: toluene di-isocyanate(TDI)；Component B: polyester polyol, polyethylene glycol, promotor, calcium carbonate, catalyst, stabilization
Agent；
Wherein, the mass fraction of each ingredient described in component B are as follows:
Polyester polyol 30%~55%, preferably 35%,
Polyethylene glycol 20%~35%, preferably 25%,
Promotor 10%~25%, preferably 15%,
Calcium carbonate 5%~20%, preferably 10%,
Catalyst 5%~15%, preferably 10%,
Stabilizer 5%~10%, preferably 5%.
In the more excellent disclosed example of the present invention, the ingredient of the promotor is organo-silicon compound, and main body is vinyl trimethoxy
Base silane, silica, the composition mass fraction of the two are as follows:
Organo-silicon compound 70%~90%, preferably 80%,
Silica 1 0%~30%, preferably 20%.
The invention also discloses the preparation processes of above-mentioned bicomponent environment-friendly type adhesive, comprising:
Component A is toluene di-isocyanate(TDI)；
The preparation step of component B: according to mass ratio, first preparing promotor, then by the pure and mild polyethylene glycol of polyester polyols according to
Secondary to be added in reaction kettle, stirring is warming up to 100 DEG C, sequentially adds promotor, calcium carbonate, catalyst, stabilizer, and stirring is equal
It after even, is cooled to room temperature, obtains component B.
By component A and component B according to mass ratio 1:(0.9~1.4 when use) mixing, after mixing evenly, i.e., usable, institute
Obtain adhesive solid content 70 ± 2%, 3000 ± 500cps of viscosity.
Beneficial effect
The invention discloses a kind of formaldehydeless dual-component polyurethane adhesive, formaldehyde is free of in component, but glue-joint strength, persistently
Performance is similar to the adhesive containing formaldehydes；Cost of material is lower, and preparing process is simple, easy to use, is applied to woodwork
The adhesive containing formaldehyde can be substituted when manufacture.
