Embodiment 1

[0039] A method for producing a rubber adhesive, the rubber adhesive is a double-ended hydroxyl polystyrene butadiene liquid rubber adhesive, and the production method comprises the following steps:

[0040] S1 lithium initiator synthesis:

[0041] S1-1: Continuously evacuate the reaction vessel, fill it with argon, and bake it for 3 times to discharge water and air. The baking temperature is 55°C, then fill it with argon to maintain the argon atmosphere, and keep the temperature at 22°C;

[0042] S1-2: In parts by weight, add 1 part of tert-butyldimethylsilyl chloride, 1.25 parts of imidazole and 2.75 parts of cyclohexane into the reaction vessel, mix and stir for 1 hour, the stirring speed is 100 rpm, and the stirring method is magnetic stirring. Then add 0.5 parts of 3-chloro-1-propanol dropwise to the reaction vessel, continue to add dropwise for 1 hour, raise the temperature to 42°C and stir for 2 hours, then let stand for 6 hours, filter out the insoluble matter to obtai...

Embodiment 2

[0049] This embodiment is basically the same as Embodiment 1, except that the temperature control in step S1-1 is different.

[0050] S1 lithium initiator synthesis:

[0051] S1-1: Vacuumize the reaction vessel continuously, fill it with argon, and bake it for 3 times to discharge water and air. The baking temperature is 60°C, then fill it with argon to maintain the argon atmosphere, and keep the temperature at 25°C.

Embodiment 3

[0053] This example is basically the same as Example 1, the difference lies in: the composition ratio of the intermediate solution in step S1-2 is different.

[0054] S1-2: In parts by weight, add 1 part of tert-butyldimethylsilyl chloride, 1.5 parts of imidazole and 2.5 parts of cyclohexane into the reaction vessel, mix and stir for 1 hour, the stirring speed is 150 rpm, and the stirring method is magnetic stirring. Then, 0.5 part of 3-chloro-1-propanol was added dropwise to the reaction vessel for 1 hour, the temperature was raised to 45° C. and the reaction was stirred for 3 hours, then allowed to stand for 7 hours, and the insoluble matter was filtered off to obtain an intermediate solution, which was sealed with argon.

Abstract

The invention discloses a method and a device for producing a rubber adhesive. The rubber adhesive is a dihydroxy-terminated polybutylbenzene liquid rubber adhesive, and the production method comprises the following steps: S1, synthesizing a lithium initiator; S2, conducting polymerization reaction: weighing 2 parts by weight of styrene, 4.6-5 parts by weight of tetrahydrofuran, 1.1-1.3 parts by weight of butadiene and 0.015-0.03 part by weight of a lithium initiator, and conducting reacting to obtain a polymerization solution; S3, carrying out an end-capping reaction; S4, conducting post-processing; and S5, carrying out ultraviolet light curing. The production device comprises a stirring barrel, an ultraviolet irradiation bin, an ultraviolet generating device and a feeding device, and a stirring telescopic rod and a lifting plate are arranged in the stirring barrel. The rubber adhesive is high in adhesive force, water resistance and corrosion resistance, oligomer active short chains with activity at the two ends are generated, and therefore the rubber adhesive is good in heat resistance and impact resistance and good in stability, extrusion conveying of the rubber adhesive is completed through a telescopic stirring rod and a lifting plate, and subpackaging operation is convenient.

Description

technical field [0001] 本发明涉及橡胶粘合剂生产制造技术领域,具体是涉及一种生产橡胶粘合剂的方法及生产装置。 Background technique [0002] 橡胶粘合剂是一类以氯丁、丁腈、丁基硅橡胶、聚硫等合成橡胶或天然橡胶为主体材料配制成的胶粘剂,其具有优良的粘弹性,适用于粘接柔软的或热膨胀系数相差悬殊的材料,例如橡胶与橡胶、橡胶与金属、塑料、皮革、木材等材料之间的粘接,在飞机制造、汽车制造、建筑、轻工、橡胶制品加工等部门有着广泛的应用。橡胶胶粘剂主要分两大类:结构型胶粘剂和非结构型胶粘剂,结构型又分溶剂胶液型和胶膜胶带型,它们多为复合体系(除聚氨酯胶外),非结构型橡胶胶粘剂可分溶液型和乳液型两大类,其中以溶液型橡胶胶粘剂(简称橡胶胶液)为主要类型。 [0003] 当我们评价一类橡胶粘合剂的性能好坏时,不光要看其粘结性能的强弱,还要考虑橡胶粘合剂的耐热性能、耐冲击性能和环保性能等,综合性能越强的橡胶实用性也越强,应用范围也越广。现有的橡胶粘合剂及其制备工艺种类多样,由于橡胶粘合剂大多使用在户外,需要经历天气条件的影响,因此,橡胶粘合剂的稳定性需要达到使用要求,而一些橡胶粘合剂在高温等条件下容易发生变质或者散发出有害物质,或者因工艺手段的缺陷使用寿命短,因此需要有更加稳定且无害的橡胶粘合剂来提高实用性。 [0004] 专利CN112321896A公开了一种橡胶改性剂、橡胶材料及制备方法和应用,采用橡胶改性剂改性得到,所述橡胶改性剂的制备方法为:将石墨粉与十六烷基三甲基溴化铵在水中搅拌分散,使石墨改性,得到混合溶液;将聚四氟乙烯微球用萘钠溶液进行表面改性处理;将聚四氟乙烯微球加入到混合溶液中搅拌反应,后处理得到橡胶改性剂。本发明制得的橡胶材料具有良好的耐高温、耐腐蚀、耐溶剂、耐老化和耐辐射性能,同时,有自润滑性和不透气性。但是,其中所含有的致癌物质萘可能会对人体健康造成危害。 Contents of the invention [0005] 针对上述存在的问题,本发明提供了一种生产橡胶粘合剂的方法及生产装置。 [0006] Technical scheme of the present invention is: [0007] 一种生产橡胶粘合剂的方法,所述橡胶粘合剂为双端羟基聚丁苯...
