Abstract

The invention relates to the technical field of modified butyl rubber, in particular to a special thermoplastic butyl spacing bar for hollow glass. The special thermoplastic butyl spacing bar comprises polyisobutene, a semi-reinforcing filler, butyl rubber, a reinforcing filler, tackifying resin, a water absorbent and a curing agent. The preparation method comprises the following steps: kneading the butyl rubber, the semi-reinforcing filler and a part of the polyisobutene, adding the reinforcing filler, the tackifying resin, the water absorbent and the rest of polyisobutene into a kneading machine, carrying out kneading, performing cooling, and adding the curing agent to obtain the special thermoplastic butyl spacing bar. The problems that production procedures of the hollow glass at a present stage are tedious and a technological process is complex in the prior art are solved in the invention. The thermoplastic butyl spacing bar has good thermoplasticity, aging resistance, ultraviolet resistance and oxidation resistance, and also has excellent heat insulation performance, excellent water vapor permeability and permanent non-curing performance. In the coating process of the hollow glass, four working procedures are changed into one working procedure, so labor cost is saved. The thermoplastic butyl spacing bar has a very wide application prospect.

Description

technical field [0001] The invention relates to the technical field of modified butyl rubber, in particular to a thermoplastic butyl spacer specially used for insulating glass and a preparation method thereof. Background technique [0002] Insulating glass has the following main characteristics: [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: The insulating glass can reduce the noise by 27-40 decibels because of the goo...
