Abstract
Abstract The subject of the invention is a composition designed for production of slide elements and surfaces of machines and equipment, consisting of 100 parts by weight of low-molecular epoxy resin on the basis of epichlorohydrin and dian condensed with 3-15 parts by weight of phenol-formaldehyde resin modified with furfuryl alcohol, 2-15 parts by weight of an organic diluent, 15-100 parts by weight of the known inorganic fillers and, optionally 2-20 parts by weight of a polymeric material of lubricating properties in powder form. The composition is obtained as a result of the condensation of resins at a temperature of 150°-170° C. and the introduction into the post-reaction mixture of organic diluents and inorganic fillers at a temperature of about 100° C. and optionally, the introduction of a polymeric material at a temperature of 50° C.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A low-friction, slide lining composition applied in the production of slide elements and surfaces of machines and equipment, containing epoxy resin and fillers, hardened with the known cross-linking agents of epoxy resins, comprising 100 parts by weight of low-molecular epoxy resin on the basis of epichlorohydrin and dian, condensed with 3-15 parts by weight of phenol-formaldehyde resin modified with furfuryl alcohol, 2-15 parts by weight of an organic diluent and 15-100 parts by weight of the known inorganic fillers selected from the group consisting of titanium white, talcum, lithophone, graphite, molybdenum disulfide, aluminum hydroxide, porcelain flour and mixtures thereof.
Claim 2
Dependent Claim
99 words
A low-friction, slide lining composition applied in the production of slide elements and surfaces of machines and equipment, containing epoxy resin and fillers, hardened with the known cross-linking agents of epoxy resins, comprising 100 parts by weight of low-molecular epoxy resin on the basis of epichlorohydrin and dian, condensed with 3-15 parts by weight of phenol-formaldehyde resin modified with furfuryl alcohol, 2-15 parts by weight of an organic diluent and 15-100 parts by weight of the known inorganic fillers selected from the group consisting of titanium white, talcum, lithophone, graphite, molybdenum disulfide, aluminum hydroxide, porcelain flour and mixtures thereof.
Claim 3
Dependent Claim
38 words
A low-friction, slide lining composition according to claim 1, containing 2-20 parts by weight of a polymeric material of lubricating properties, selected from the group of polyethylenes possessing a molecular weight above 1 million and in powder form.
Claim 4
Dependent Claim
25 words
A low-friction, slide lining composition according to claim 2, wherein the organic diluent dibutyl phthalate, phenyl-glycide ether, a mixture thereof, or butyl-glycide ether is applied.
Claim 5
Independent Claim
137 words
A method of producing the low-friction slide lining composition applied in the slide elements and surfaces of machines and equipment, which comprises the steps of condensing 100 parts by weight of low-molecular epoxy resin on the basis of epichlorohydrin and dian with 3-15 parts by weight of phenol-formaldehyde resin modified with furfuryl alcohol at a temperature of 150°-170° C.; introducing into the condensation product 2-15 parts by weight of an organic diluent and 15-100 parts by weight of the known inorganic fillers or mixtures thereof, at a temperature of 100° C.; adding 2-20 parts by weight of a polymeric material of lubricating properties at a temperature of 50° C., and adding, immediately prior to the composition's use, the known hardeners of epoxy resins in an amount proportional to the amount of epoxy resin present in the composition.
