Abstract
Does is the invention discloses a kind of light fixture neoprene packing waterproof glue, be made up of the raw material of following weight part: 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 present invention is by being polymerized with alkenyl succinic acid ethyl acetate, rosin, divinyl, to isoprene-isobutylene rubber CBK139 chloroprene rubber (A-90? NEC chemistry) adopt the modification of methyltrimethoxy silane accelerant CZ, aluminate coupling agent DL-411, add its cohesiveness, network distribution structure is formed between inorganic point and organic molecule, significantly improve the water tolerance of product, weathering resistance and high temperature resistant, resistance to low temperature, strong adhesion, snappiness is better, and sealing property 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
Light fixture waterproof gasket cement is that one is out of shape with trim shape, not easily trickles, has certain close-burning sealing material.It is a kind of unsetting material that maybe can squeeze of flowing in use, can pointing closure seam, is bondd by drying, temperature variation, solvent evaporates, chemically crosslinked and stablizing with base material, and it is shaped gradually becomes that plasticity is solid-state, viscoelastic state or elaxtic seal.
For the light fixture of outdoor, because Chinese former vast, Environmental variations in all parts of the country is large, outdoor lamp bears the alternately change effect of the envrionment conditionss such as daylight, sleet and blast for a long time, it needs to have good water tolerance, weathering resistance, high temperature resistant, resistance to low temperature, but the water tolerance of current light fixture water-tight glue, weathering resistance, high temperature resistant, the equal Shortcomings of resistance to low temperature, snappiness and sealing property, be badly in need of improving.
Send out summary of the invention
The object 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, it is characterized in that being made up of the raw material of following weight part: 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-4114-5, Starso 2-3, polyisobutene 3-5.
The preparation method of described light fixture neoprene packing waterproof glue, it is characterized in that comprising the following steps: by ethyl acetate, rosin, divinyl mixing, be heated to 70-80 DEG C, add alkenyl succinic acid, methylethyl ketone peroxide again, stirring reaction 40-60 minute, add polyglycerol fatty acid ester, Starso again, continue stirring reaction 1-2 hour; Chloroprene rubber (A-90 NEC chemistry) is dissolved in dimethylbenzene, is heated to 60-70 DEG C, adds accelerant CZ, aluminate coupling agent DL-411, stir 40-60 minute; Aforementioned each reaction mass is mixed with other leftover materials, stirs 30-45 minute, obtain.
The invention has the beneficial effects as follows:
The present invention is by being polymerized with alkenyl succinic acid ethyl acetate, rosin, divinyl, isoprene-isobutylene rubber CBK139 chloroprene rubber (A-90 NEC chemistry) is adopted to the modification of methyltrimethoxy silane accelerant CZ, aluminate coupling agent DL-411, add its cohesiveness, network distribution structure is formed between inorganic point and organic molecule, significantly improve the water tolerance of product, weathering resistance and high temperature resistant, resistance to low temperature, strong adhesion, snappiness is better, and sealing property is excellent.
