Description
Technical field
The present invention relates to a kind of adhesive, more particularly to a kind of environment-friendly type solvent-free for chinampa is double
Part polyurethane adhesive.
Background technique
Chinampa is made of the adhesive of careless silk, base fabric and secured careless silk in base fabric, and careless silk is usually tufting
In base fabric, chinampa than natural lawn have more excellent performance, be that maintenance is simple, draining rapidly, it is round-the-clock can
With and levelling of the land degree it is excellent, be widely used in athletic ground, public practice Condom, indoor beautifying and landscape paving
If.However in use process other than careless silk performance difference, most important is exactly fastness of the careless silk in base fabric.Due to passing
The disadvantages of adhesive styrene-butadiene latex of uniting has bottom liner hard, and the big easy to fall off, adhesion strength of brittleness is not high and hydrolytic resistance is poor, causes
Careless silk is easy to fall off from base fabric, reduces lawn service life.
Polyurethane adhesive (PU) has a large amount of polar groups, and molecule designability, bonding range is wide, and hardness is adjustable
Etc. advantages, there is very strong caking property to a variety of substrates, meanwhile, by be crosslinked with crystallization, improve its cohesive force, toughness and glue
Knotting strength, has superior anti-aging, hydrolytic resistance and erosion-resisting characteristics, and market application is increasingly taken seriously.How
It is further modified to be suitable for the hot spot that artificial grassplot back glue is research and development.
Summary of the invention
The present invention provides a kind of environment-friendly type solvent-free bi-component polyurethane adhesive for chinampa, the environment-friendly types
Solvent-free double-component polyurethane adhesive uses polyether polyol for main base-material, has compared to polyester polyol superior resistance to low
Temperature, anti-hydrolytic performance；It takes solvent-free and there is the feature of environmental protection, smell is low, and it is nontoxic and pollution-free, while there is excellent bonding again
Property, chinampa can be perfectly suitable for.
The present invention is achieved by the following technical solutions:
Environment-friendly type solvent-free bi-component polyurethane adhesive for chinampa of the invention, including component A and component
B, described in component A mixed according to parts by weight by following components:
The component B is isocyanates, its parts by weight is 50~80 parts when use.
The above-mentioned environment-friendly type solvent-free bi-component polyurethane adhesive of the present invention, further technical solution is described
Using glycerine as initiator when prepared by high molecular weight polyether, number-average molecular weight is in 3000-6000, degree of functionality 2-3；It is low
Using dipropylene glycol as initiator when prepared by molecular weight polyether polyol, one or more polyethers of the number-average molecular weight in 200-1000
Polyalcohol, more specifically, molecular weight are preferably 400-800 polyether polyol, degree of functionality 2.
The above-mentioned environment-friendly type solvent-free bi-component polyurethane adhesive of the present invention, further technical solution can also be
The chain extender is dipropylene glycol (DPG), diglycol (DEG), 1,2-PD or 1,4-butanediol；It is described
Filler be kaolin, calcium carbonate, talcum powder or aluminium hydroxide one or more.
The above-mentioned environment-friendly type solvent-free bi-component polyurethane adhesive of the present invention, further technical solution can also be
The catalyst is embodied in low using the amine or metal gellike type catalysts of one or more of retardances
The lower delay of temperature, the rapid catalytic curing reaction of high temperature.Further technical solution is that the amine or metal gellike type are anti-
It answers and postpones under catalyst low temperature, high temperature rapid catalytic curing reaction is embodied in 30 DEG C of room temperature and following has deferred reaction
Property, gel time >=15min；90 DEG C of high temperature and sharply above catalysis reaction, gel time≤7min.Further technical side
Case be the amine gel-type catalysts be bis- (dimethylaminoethyl) ethers, triethylenediamine, diethylenetriamine or
1,8 diazacyclo hendecenes；The metal gellike type catalysts are stannous octoate, two mercaptan dioctyl tins, mercaptan
Dibutyl tin or diacetyl acetone nickel.
Metal-based catalysts catalytic activity is generally lower than amine, reacts slow under low temperature, and high temperature accelerates to be catalyzed, however gel
Performance is more excellent.Why the amines catalyst taken has deferred reaction performance, mainly reacts generation with acid due to it
A kind of complex compound of ammonium salt class is concretely reacted using the amine of 1mol with the monoacid of 1~2mol or binary acid
(30 DEG C~50 DEG C) produce ammonium salt, then isolated.The ammonium salt complex compound delay effect that weak acid and tertiary amine are formed is eager to excel
In the ammonium salt complex compound that strong acid and tertiary amine are formed.The formation of ammonium salt complex compound is (by taking DBU as an example) as follows:
The above-mentioned environment-friendly type solvent-free bi-component polyurethane adhesive of the present invention, further technical solution can also be
After mixing, the lower 25 DEG C of optimum viscosity ranges of room temperature mix elder generation's component A in 10000-35000cps, then with component B when use
Uniformly after, can gluing in chinampa bottom back.Further technical solution is gluing in its unlucky back of chinampa bottom
Glue amount is in 500-1000g/m2, and by infrared or long oven post-cure.
The invention has the following beneficial effects compared with prior art:
Environment-friendly type solvent-free bi-component polyurethane adhesive of the invention uses polyether polyol for main base-material, compares polyester
Polyalcohol has superior low temperature resistant, anti-hydrolytic performance；It takes solvent-free and there is the feature of environmental protection, smell is low, and it is nontoxic and pollution-free,
There is excellent caking property again simultaneously, chinampa can be perfectly suitable for.
