Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-temperature-resistant modified acrylate pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is an adhesive that is sensitive to external pressure. It only needs to provide a slight pressure to make it stick to the object. It is suitable for various fields, such as electronic machinery manufacturing, automobile Manufacturing and daily necessities, among which pressure-sensitive adhesives are widely used in consumer electronics fields such as mobile phones and car displays, which require that the pressure-sensitive adhesives used in them are resistant to high temperatures without residual glue, and the peeling force climbs less than 1 times after high temperatures. However, the raw materials for the preparation of existing pressure-sensitive adhesives are expensive, which makes the production cost relative...
