Abstract
The invention discloses a composite solvent to prepare neoprene adhesive, which comprises the following parts: 130# solvent oil, dimethyl carbonate, butyl acetate or acetic ester, cyclohexyl-methane or cyclohexane, methyl ethyl ketone or pentanone. The solvent possesses aromatic smell and little toxicity, which improves adhesive strength.
Description
Technical field
The present invention relates to a kind of mixed solvent that is used to prepare chloroprene rubber adhesive agent.
Background technology
The chloroprene rubber adhesive agent that is made by chloroprene rubber and methyl methacrylate (MMA) graft copolymerization is mainly used in bonding between leatheroid, synthetic leather, simulated leather and the corium, chloroprene rubber adhesive agent is a kind of Solvent Adhesive, benzene,toluene,xylene is the fine solvent of chloroprene rubber, being solvent with " triphen " can both play best effect to its preparation technology and product performance, and therefore " triphen " is used widely in the manufacturing field of chloroprene rubber adhesive agent.But " triphen " is very big to workman's healthy and environmental influence; should use less as far as possible; therefore existing national standard " GB18583-2001 " to solvent-borne type rubber based adhesives regulation benzene less than 0.5%, " triphen " less than 20%; still allow the benzene kind solvent below 20%, these solvents are unfavorable for environment protection, also are unfavorable for that the constructor's is healthy.Real environment-friendly type solvent should be to human body toxicological harmless, environmentally safe, specifically, should there be benzene kind solvent, no free formaldehyde, no chlorinated solvent, in general, for Solution Chloroprene Rubber Adhesives, as benzene≤2 ‰, toluene≤5 ‰, free formaldehyde≤0.1 ‰, chlorinated solvent≤5 ‰, can regard environmentally friendly machine as.
CN1179485A disclose and a kind ofly do not contained " triphen ' and the graft neoprene adhesive mixed solvent system, mixed solvent is made up of ethyl acetate, acetone, 120# industrial naptha, butanone or ethyl acetate, hexanaphthene, 120# industrial naptha, butanone.But this mixed solvent system requires graft reaction to carry out under the lower situation of temperature, and the graft process condition is restricted.
CN1451708A discloses a kind of mixed solvent system of environment-friendly universal glue, and mixed solvent is made up of 6# solvent oil, acetone, hexanaphthene.This mixed solvent system also requires graft reaction to carry out under the lower situation of temperature, and the graft process condition is restricted.
CN1557899A discloses a kind of mixed solvent system of neoprene adhesive, uses the mixed solvent system of pentamethylene Type B solvent, methylethylketone, vinyl acetic monomer, 120# industrial naptha to make solvent.But this mixed solvent system price is higher, and production cost is bigger.
CN1188786A discloses a kind of mixed solvent system of multielement graft neoprene adhesive, uses toluene, butanone, ethyl acetate to make solvent.Still used noxious solvent toluene, operator's health and environment brought harm.
87,105,096 1 kinds of adhesive made up of polychloroprene rubber of application number use formaldehyde ester to make solvent.But solvent is of little use, and price is higher, and production cost is bigger.
Summary of the invention
Purpose of the present invention aims to provide the solvent that a kind of novel, smell fragrance, toxicity is little, the feature of environmental protection is good mixed solvent replace containing " triphen ", as the production solvent of chloroprene rubber adhesive agent.
The said environment-friendly type mixed solvent of the present invention is to human body toxicological harmless, environmentally safe, specifically, not containing benezene solvent, free formaldehyde, chlorinated solvent, it is made up of methylcarbonate, N-BUTYL ACETATE or ethyl acetate, 130# solvent oil, methylcyclohexane or hexanaphthene, butanone or pentanone, mixes according to a certain percentage.
The proportioning of each component is a benchmark for 100 parts with the parts by weight of 130# solvent oil in the said mixed solvent, and the parts by weight of other components are respectively:
Methylcarbonate: 0～70 part
N-BUTYL ACETATE or ethyl acetate: 0～80 part
Methylcyclohexane or hexanaphthene: 30～60 parts
Butanone or pentanone: 0～90 part
The mixed solvent advantage that the present invention makes is: smell is little, toxicity is low, the feature of environmental protection is good, can satisfy the requirement of chloroprene rubber and methyl methacrylate (MMA) grafting optimised process, and the chloroprene rubber adhesive agent product colour that makes is shallow, transparency good, the bonding strength height.
Embodiment
With embodiment the present invention is further specified below.
Embodiment 1: get 100 parts of 130# solvent oils, 40 parts of methylcarbonates, 33 parts of N-BUTYL ACETATEs, 22 parts of methylcyclohexanes, 27 parts of mixing and stirring of butanone, get as clear as crystal colourless solvent, product odour is little, toxicity is low, the feature of environmental protection is good, good to the chloroprene rubber solvability, synthesis technique to neoprene latex has no adverse effects, with MMA monomer conversion behind the MMA graft reaction be 41%, the product initial stage pulling force that makes reaches 3.4KN/m.
Embodiment 2～6: the preparation method is with embodiment 1, and 100 parts of 130# solvent oils change the consumption of methylcarbonate, N-BUTYL ACETATE, ethyl acetate, methylcyclohexane, hexanaphthene, butanone, pentanone, result such as following table 1:
Table 1: the result of use of the mixed solvent of different proportionings
Claims (1)
1, a kind of mixed solvent that is used to prepare chloroprene rubber adhesive agent is characterized in that: should be made up of mixed solvent methylcarbonate, N-BUTYL ACETATE or ethyl acetate, 130# solvent oil, methylcyclohexane or hexanaphthene, butanone or pentanone; The proportioning of each component is a benchmark for 100 parts with the parts by weight of 130# solvent oil in the mixed solvent, and the parts by weight of other components are respectively:
Methylcarbonate: 0～70 part;
N-BUTYL ACETATE or ethyl acetate: 0～80 part;
Methylcyclohexane or hexanaphthene: 30～60 parts;
Butanone or pentanone: 0～90 part.
