Abstract
The invention discloses chloroprene rubber sealing waterproof glue for lamps. The chloroprene rubber sealing waterproof glue for lamps is prepared from the following materials in parts by weight: 24-26 parts of chloroprene rubber (A-90 DENKA), 92-98 parts of dimethyl benzene, 30-35 parts of ethyl acetate, 8-10 parts of rosin, 3-4 parts of butadiene, 18-22 parts of diatomite powder, 10-12 parts of feldspar powder, 5-8 parts of alkenyl succinic acid, 2-3 parts of methyl ethyl ketone peroxide, 1-2 parts of accelerant CZ, 3-5 parts of barium sulfate, 8-10 parts of vermiculite powder, 4-5 parts of aluminate coupling agent DL-411, 2-3 parts of sodium metasilicate and 3-5 parts of polyisobutene. The caking property of the chloroprene rubber sealing waterproof glue for lamps is increased by polymerizing ethyl acetate, rosin, butadiene and alkenyl succinic acid, and modifying the butyl rubber CBK139 chloroprene rubber (A-90 DENKA) by adopting methyl trimethoxy silane accelerant CZ and aluminate coupling agent DL-411; a network distribution structure is formed between an inorganic molecule and an organic molecule, so that water resistance, weather resistance, heat resistance, low-temperature resistance of the product are obviously improved; and besides, the adhesion is strong, the flexibility is better and the sealing performance is excellent.
Description
Technical field
A kind of water-tight glue of the present invention and preparation method thereof, particularly a kind of light fixture neoprene packing waterproof glue and preparation method thereof.
Background technology
The light fixture waterproof gasket cement is a kind ofly to be out of shape with the trim shape, is difficult for trickling, and certain close-burning sealing material is arranged.But it is a kind of unsetting material of mobile or squeeze note in use, can pointing sealing seam, bond by drying, temperature variation, solvent evaporates, chemically crosslinked and with base material is stable, and it is finalized the design gradually becomes that plasticity is solid-state, viscoelastic attitude or elaxtic seal.
Be used for outdoor light fixture, because Chinese former vast, physical environment in all parts of the country changes greatly, outdoor lamp bears the alternately variation effect of envrionment conditionss such as daylight, sleet and blast for a long time, it need have water tolerance, weathering resistance, high temperature resistant, resistance to low temperature preferably, but all there are deficiency in the water tolerance of present light fixture water-tight glue, weathering resistance, high temperature resistant, resistance to low temperature, snappiness and sealing property, are badly in need of improving.
Send out summary of the invention
The purpose of this invention is to provide light fixture neoprene packing waterproof glue and preparation method thereof.
The technical solution used in the present invention is:
A kind of light fixture neoprene packing waterproof glue is characterized in that it being that raw material by following weight part is made: chloroprene rubber (A-90 NEC chemistry) 24-26, dimethylbenzene 92-98, ethyl acetate 30-35, rosin 8-10, divinyl 3-4, diatomite in powder 18-22, feldspar in powder 10-12, alkenyl succinic acid 5-8, polyglycerol fatty acid ester 2-3, methylethyl ketone peroxide 1-2, accelerant CZ 1-2, barium sulfate 3-5, vermiculite power 8-10, aluminate coupling agent DL-411 4-5, Starso 2-3, polyisobutene 3-5.
The described light fixture preparation method of neoprene packing waterproof glue, it is characterized in that may further comprise the steps: ethyl acetate, rosin, divinyl are mixed, be heated to 70-80 ℃, add alkenyl succinic acid, methylethyl ketone peroxide again, stirring reaction 40-60 minute, add polyglycerol fatty acid ester, Starso again, continued stirring reaction 1-2 hour; Chloroprene rubber (A-90 NEC chemistry) is dissolved in the dimethylbenzene, is heated to 60-70 ℃, adds accelerant CZ, aluminate coupling agent DL-411, stirs 40-60 minute; Aforementioned each reaction mass is mixed with other leftover materials, stirred 30-45 minute, obtain.
The invention has the beneficial effects as follows:
The present invention is by the polymerization to ethyl acetate, rosin, divinyl and alkenyl succinic acid, isoprene-isobutylene rubber CBK139 chloroprene rubber (A-90 NEC chemistry) is adopted the modification of methyltrimethoxy silane accelerant CZ, aluminate coupling agent DL-411, increased its cohesiveness, form the network distributed architecture between inorganic branch and the organic molecule, water tolerance, weathering resistance and high temperature resistant, the resistance to low temperature of product have obviously been improved, strong adhesion, snappiness is better, and sealing property is good.
