Problems solved by technology

Traditionally produced adhesives for boats are not strong in weather resistance, water resistance, cohesiveness and medium resistance, resulting in serious degumming, which affects the normal work of boats. In order to pursue higher quality products, production and development needs, the existing adhesive needs to be modified to meet the needs

Embodiment Construction

[0020] A composite adhesive for inflatable boats, made of the following components in parts by weight, bisphenol F type epoxy resin 47, bisphenol A type epoxy resin 15, isophorone diisocyanate 5, dimethylol Propionic acid 20, mica powder 0.1, polyester diol 24, dibutyl phthalate 0.3, acrylamide 8, borax 0.3, 1,4-butanediol 20, methyl methacrylate 5, maple poplar Seed and bamboo powder mixed cooking liquid 4, sodium lignosulfonate 1, epoxy soybean oil 3;

[0021] The bisphenol F type epoxy resin is pretreated: heat the bisphenol F type epoxy resin to 140°C, then add 4% by mass of amino polysiloxane and bentonite mixture, stir at 450r / min for 40 minutes, That is, the aminopolysiloxane and nano-bentonite mixture are mixed at a mass ratio of 4:1, and the nano-bentonite is soaked in a maleic acid solution with a mass concentration of 6.4% at 38°C for 45 minutes, and filtered , drying at 48°C, the particle size of the nano-bentonite is 20-22nm;

[0022] The mica powder is pretreat...

Abstract

The invention discloses a composite adhesive for inflatable boats. The composite adhesive is prepared from bisphenol-F epoxy resin, bisphenol-A epoxy resin, isophorone diisocyanate, dimethylolpropionic acid, mica powder, polyester glycol, dibutyl phthalate, acrylamide, borax, 1,4-butanediol, methyl methacrylate and mixed cooking liquid of pterocarya stenoptera seeds and bamboo powder. According to the adhesive prepared by improving a production technology and formula, layering cannot be generated in the curing process, and the curing speed is high; heat emitted by curing is low, and the shrinkage rate is small; the cured product is flat in surface, bright, high in hardness, excellent in mechanical property, good in heat resistance, small in heat expansion coefficient and extremely good in water resistance; the adhesive is suitable for being applied to the inflatable boats such as drift boats, kayaks and assault boats.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a composite adhesive for inflatable boats. Background technique [0002] In the manufacture and maintenance of inflatable boats, a large amount of adhesives are needed. The application of epoxy adhesives on ships is mainly epoxy resin. There are many kinds of adhesives and they are widely used. Traditionally produced adhesives for boats are not strong in weather resistance, water resistance, cohesiveness and medium resistance, resulting in serious degumming, which affects the normal work of boats. In order to pursue higher quality products, production and development The needs of existing adhesives need to be modified to meet the needs. Contents of the invention [0003] The object of the present invention is to provide a composite adhesive for inflatable boats. [0004] The present invention is realized through the following technical solutions: [0005] A composite adhesive for in...
