Problems solved by technology

In addition, the fluency of insulating glass butyl glue on the market is not good, so workers are easily burned when coating; and if the glue temperature is low (110-120) and the fluency is not good, it is easy to break the line and cause breakpoints
If there is a breakpoint, it needs to be reprinted, and the process of reprinting is a waste of time
If it is not repaired, the sealing effect will not be achieved, which will affect the quality of the product

Abstract

The invention relates to the technical field of modified butyl rubber, in particular to special non-sticky non-scalding butyl rubber for hollow glass. The special non-sticky non-scalding butyl rubber comprises low-molecular-weight polyisobutene, medium-molecular-weight polyisobutene, a semi-reinforcing filler, butyl rubber, a reinforcing filler, tackifying resin and plasticizing resin. The preparation method comprises the following steps: adding the butyl rubber, the semi-reinforcing filler and the low-molecular-weight polyisobutene into a kneading machine for kneaded in advance, then adding the remaining materials into the kneading machine for kneading, and performing hollowing to obtain the rubber. The problem that the gluing temperature of butyl rubber for hollow glass is very high in a coating process in the prior art is solved. The gluing temperature of the non-sticky non-scalding butyl rubber is 105-120 DEG C, and the butyl rubber is non-sticky and non-scalding, can realize high-speed smoothness, and retains all performances of the original butyl rubber for hollow glass. The non-sticky non-scalding butyl rubber realizes high-speed smoothness, is not prone to a breakpoint phenomenon, improves gluing efficiency and yield, and can avoid hand scalding or scalds in a gluing process due to the fact that gluing temperature is low.

Description

technical field [0001] The invention relates to the technical field of modified butyl rubber, in particular to a non-sticky and non-scalding butyl rubber specially used for insulating glass and a preparation method thereof. Background technique [0002] Main features of insulating glass: [0003] 1. Superior energy-saving effect: The energy consumption of modern buildings is mainly air conditioning and lighting, the former accounts for 55% of energy consumption, the latter accounts for 23% of energy consumption, and glass is the thinnest and most easily heat-transmitting part of the building's outer wall Material. Due to the butyl seal on the aluminum frame and the internal desiccant passing through the gap above the aluminum frame to keep the air in the hollow glass dry for a long time, the insulating glass has excellent thermal insulation performance. [0004] 2. High sound insulation: Insulating glass can reduce the noise by 27-40 decibels because of the good sealing pe...
