Problems solved by technology

In some outdoor environments, the environment is relatively harsh, and the performance requirements for pressure-sensitive adhesives are relatively high. Some traditional pressure-sensitive adhesives have insufficient cold and heat resistance, and are prone to fall off due to insufficient viscosity during use.

Abstract

The invention discloses a heat-resistant cold-resistant outdoor pressure-sensitive adhesive and a preparation method thereof, and particularly relates to the technical field of pressure-sensitive adhesive. The pressure-sensitive adhesive comprises the following components in parts by weight: 100-150 parts of natural rubber, 100-150 parts of tackifying resin, 30-50 parts of a plasticizer, 5-10 parts of a vulcanizing agent, 5-10 parts of an anti-aging agent, 10-20 parts of a softening agent, 10-20 parts of a mixed filler and 1-5 parts of titanium dioxide, wherein the tackifying resin is a mixture of rosin resin, terpene resin, maleic resin and water white resin, and the softening agent is a mixture of lanolin, lecithin, dibutyl phthalate and glycerol. According to the invention, the body viscosity of the pressure-sensitive adhesive can be reduced, and adhesiveness and coating process of the pressure-sensitive adhesive to a base material are improved. The initial viscosity at low temperature is improved, and cold resistance and heat resistance of the pressure-sensitive adhesive are improved, so that the pressure-sensitive adhesive does not fall off easily when being used in a severe outdoor environment.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, more specifically, the invention relates to a heat-resistant and cold-resistant outdoor pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Adhesive bonding (bonding, bonding, cementation, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives. It has the characteristics of continuous stress distribution, light weight, or sealing, and low temperature in most processes. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is the fastest growing in modern times, with a wide range of applications, and has a major impact on the progress of high-tech science and technology and the improvement of people's daily life. Therefore, it is very important to research, develop and produce vario...
