The tackifier is C5 petroleum resin, also called carbon five resin, has good tackifying property, heat resistance and water resistance, the tackifying effect is generally better than that of C9 resin, and within a certain range, the pressure-sensitive adhesive bonding property is reduced along with the increase of the consumption of the C5 petroleum resin, and the cohesive strength and the shear strength are increased.
The plasticizer is more than one of Polyisobutylene (PIB) which is a high molecular weight and low molecular weight molecular plasticizer. Compared with the common ester plasticizer, the molecular weight of the pressure-sensitive adhesive is larger, the pressure-sensitive adhesive is not easy to migrate at high temperature, and the prepared pressure-sensitive adhesive has good initial viscosity at low temperature and good elongation, flexibility and flexibility.
The filler is light calcium carbonate, also called precipitated calcium carbonate, and has the advantages of fine particles, regular shape and large specific surface area. The addition of the filler can improve the processing performance of the pressure-sensitive adhesive, improve the stability and the aging resistance of the adhesive and reduce the production cost.
The anti-aging agent is 4010NA (N-isopropyl-N' -phenyl-p-phenylenediamine), is an amine anti-aging agent, has a melting point of 70 ℃, is easily dispersed in rubber, and has an excellent protection effect on aging caused by heat, oxygen and light.
The modifier is chlorohydrin rubber (ECO) with chloromethyl-containing side chains and highly saturated structure, and a small amount of ECO is introduced to interact with polar groups on the surfaces of adherends such as butyl waterproof coiled materials, color steel plates and the like, so that the bonding strength on the surfaces of the two objects is improved.
