Abstract
The present invention relates to the use of dichloro propane, and is especially the use of dichloro propane as diluent in producing polyurethane adhesive. Using dichloro propane as the side product from chloroepoxy propane production and toluene as the diluent in producing polyurethane adhesive can lower the polyurethane adhesive producing cost. At the same time, dichloro propane with unique molecular structure can raise the permeating rate and wettability of polyurethane on fabric to raise the adhering fastness.
Description
Technical field
The present invention relates to the purposes of propylene dichloride, the application of the thinner during especially propylene dichloride is produced as polyurethane adhesive.
Background technology
Polyurethane glue stick (PU) is to contain the ammoniacum base on a kind of major key (NHCOO-) and the isocyanato (NCO) high molecular synthetic material of class.Be mainly used in aspects such as weaving, process hides, OXFORD.Because become the later stage in glue stage to need to dilute colloid with a large amount of thinners in polyurethane adhesive production, thinner accounts for 65～70% of total amount.For a long time, enterprise all adopts materials such as toluene, ketone, ester class to make thinner in PU produces both at home and abroad.But along with skyrocketing of oil price, the toluene price is from initial about 3,000 yuan/ton, goes up so far about 10,000 yuan/ton, and the production cost of PU increases greatly, and market in urgent need is a kind of can satisfy the PU manufacturing technique requirent, the thinner that can save production cost again simultaneously.In addition, materials such as existing employing toluene, ketone, ester class are done the polyurethane glue stick that thinner makes, and can produce gel in the winter time and the flock phenomenon occur, could use after need heating it during use.
Summary of the invention
The technical problem to be solved in the present invention is: solve existing polyurethane glue stick and can produce gel in the winter time and flock phenomenon problem occur, provide a kind of PU manufacturing technique requirent that both satisfied, the thinner during the polyurethane adhesive that can save production cost is again simultaneously produced.
The technical solution adopted for the present invention to solve the technical problems is: utilize epoxy chloropropane to produce the by product propylene dichloride, cooperate toluene as the thinner that becomes the later stage in glue stage in the production of polyurethane glue stick, the add-on of thinner is 65～70% of a polyurethane glue stick gross weight.
The invention has the beneficial effects as follows, the present invention utilizes epoxy chloropropane to produce the by product propylene dichloride, cooperate toluene as the thinner that becomes the later stage in glue stage in the production of polyurethane glue stick, saved production cost, solved PU and produced gel and flock problem winter, produced now and occur gel and flock phenomenon winter never again, because the distinctive molecular structure of propylene dichloride, improved rate of permeation and the wettability of PU, thereby improved adhesive fastness fabric.
Embodiment
In most preferred embodiment of the present invention, epoxy chloropropane is produced the by product propylene dichloride, cooperate toluene as the thinner in the production of polyurethane glue stick, by weight percentage, propylene dichloride 75～80% and 20～25% is hybridly prepared into thinner.Become the later stage in glue stage to add above-mentioned thinner in the production of polyurethane glue stick and dilute colloid, the thinner add-on is 65～70% of a polyurethane glue stick gross weight.Utilize epoxy chloropropane to produce the by product propylene dichloride, cooperate toluene as the thinner that becomes the later stage in glue stage in the production of polyurethane glue stick, saved production cost, solve PU and produced gel and flock problem winter, produce now and occur gel and flock phenomenon winter never again, because the distinctive molecular structure of propylene dichloride has improved rate of permeation and the wettability of PU to fabric, thereby has improved adhesive fastness.
Claims (2)
1. the application of the thinner during propylene dichloride is produced as the polyurethane glue stick, it is characterized in that: by weight percentage, this thinner comprises:
