Abstract
The invention relates to a leather adhesive, and belongs to the technical field of adhesives. The leather adhesive comprises components in parts by weight as follows: component A: 20-40 parts of lysine diisocyanate; and components B: 30-60 parts of chloroprene rubber, 2-4 parts of nano zinc oxide, 2-5 parts of an anti-ageing agent, 1-3 parts of a mildew preventive and 100-120 parts of a mixed solvent, wherein the mixed solvent is a mixture of methylbenzene and ethyl acetate, and the mass ratio of the methylbenzene and ethyl acetate is (1:1)-(1:3). The leather adhesive has excellent water resistance and solvent resistance, good softness, high adhesive strength and good transparency; and simultaneously, the leather adhesive has excellent mildew-proof and deodorization functions and is suitable for adhesion of not only leather but also other textiles.
Description
Technical field
The invention belongs to technical field of adhesive, be specifically related to a kind of leather adhesive.
Background technology
At present, the kind of tackiness agent is a lot, the kind of leather adhesive is quite a few, in the prior art, there is the defects such as poor water resistance, snappiness is poor, adhesive fastness is low in the leather adhesive that bonding leather is used, and in the tackiness agent of prior art, there is no the function of mildew-resistant and deodorizing, therefore how overcoming the deficiencies in the prior art is problems that current technical field of adhesive is needed solution badly.
Summary of the invention
The object of the invention is, in order to solve the deficiencies in the prior art, provides a kind of leather adhesive and preparation method thereof, and this tackiness agent has good water tolerance and solvent resistance, and flexibility is good, and cohesive strength is high.
The technical solution used in the present invention is as follows:
A leather adhesive, comprises the following component according to parts by weight meter:
A component: 20 ~ 40 parts of lysinediisocyanate;
B component: 30 ~ 60 parts of chloroprene rubbers, 2 ~ 4 parts of nano zine oxides, 2 ~ 5 parts, anti-aging agent, 1 ~ 3 part of mould inhibitor, 100 ~ 120 parts of mixed solvents.
Described mixed solvent is the mixture of toluene and ethyl acetate, and its mass ratio is 1:1 ~ 1:3.
Further preferably described anti-aging agent is 4 a pair ofs (2.2-dimethyl benzyl) pentanoic.
Further preferably described mould inhibitor is Kathon CG.
During use, after chloroprene rubber, nano zine oxide, anti-aging agent and mould inhibitor are dissolved in and are stirred in mixed solvent, add wherein again lysinediisocyanate, continue to be stirred to and mix, prepare tackiness agent, then smear, when it is half-dried, bondd, and applied certain pressure, under room temperature, solidified.
compared with prior art, its beneficial effect is in the present invention:leather adhesive of the present invention has good water tolerance and solvent resistance, and flexibility is good, and cohesive strength is high, and the transparency is good, has good mildew-resistant and the effect of deodorizing simultaneously, is not only applicable to the bonding of leather, also can be used as the bonding of other textiless.
