Problems solved by technology

[0004] The cured adhesive layer of the epoxy resin coating layer is hard and brittle, and it is not resistant to yellowing, and the buffer protection effect is not good; the high price of solvent-based fluoroplastics limits its industrialization; polyurethane is prone to yellowing and luminous flux attenuation; and silicon Rubber and silicone resins are relatively viscous, making it difficult to form thinner coatings when applied

Abstract

The invention relates to the field of glue production technology and in particular relates to anti-explosion glue for a bulb. The anti-explosion glue comprises the following components by mass fraction: 15-25% of thermoplastic elastomer, 5-10% of butyl acetate, 50-75% of ethylcyclohexane, 10-20% of carbon hydrocarbon solvent, 0.1-0.5% of compound stabilizer and 0.2-1.0% of yellowing resistant tackifier. The anti-explosion glue has the technical effects that the anti-explosion glue has good cushion protection performance, is resistant to yellowing, is easy to coat, is lower in cost and adapts to the requirements of industrialization; when the thickness is more than 3.5mu m, the coated bulb can pass the drop test of a UL1993 standard method.

Description

technical field [0001] The invention relates to the technical field of glue production, in particular to a light bulb explosion-proof glue and a preparation method thereof. Background technique [0002] In the prior art, the outer cover of lamps and lanterns is generally made of glass. Compared with resin lamp shades, the lamp shade made of glass has better heat dissipation effect and lower cost, but the lamp shade made of glass is easy to be damaged. Glass shards will fly, threatening personal safety. [0003] For this reason, many manufacturers have produced explosion-proof lamps, most of which are coated with explosion-proof layers on the surface of the bulbs. These explosion-proof layers include epoxy resins, fluoroplastics, silicones, polyurethanes, and silicone resins. [0004] The cured adhesive layer of the epoxy resin coating layer is hard and brittle, and it is not resistant to yellowing, and the buffer protection effect is not good; the high price of solvent-base...
