Description
Technical Field
The invention belongs to the technical field of modified plastics, and particularly relates to a polybutylene terephthalate mixture and a preparation method thereof.
Background
The polybutylene terephthalate has excellent mechanical property, electrical property, heat resistance, fatigue resistance and creep resistance, and has low water absorption rate and good dimensional stability. The polybutylene terephthalate has fast crystallization and excellent chemical solvent resistance. The polybutylene terephthalate modified material is widely applied to a plurality of fields of automobiles, industry, electronics and electrics, IT, household appliances, OA and the like.
The polybutylene terephthalate has better barrier property, so the polybutylene terephthalate material also has certain application in the fields of film packaging and sealed containers. As the polybutylene terephthalate material has very outstanding organic solvent resistance, very few reports are made on the polybutylene terephthalateThe solvent resistance of the butanediol formate modified material can be improved. In some special fields, such as single-component rubber tubes and double-component rubber tubes, especially when used for containing chemically corrosive glue solution, the solvent resistance of the polybutylene terephthalate modified material can hardly meet the requirement. The rubber tube is usually filled with acrylic acid glue, epoxy resin, PU glue, electronic potting glue, bi-component organic silica gel and the like, and is required to have good glue corrosion resistance and good toughness to resist damage caused by accidental falling in the use process, and the impact strength of a cantilever beam notch under the ISO standard is usually required to be not lower than 6kJ/m2. Taking an acrylic adhesive as an example, the acrylic adhesive generally contains a methacrylic acid monomer, an acrylate copolymer, benzoin propyl ether, an alpha-methyl styrene oligomer, an activator and the like, has high requirements on barrier property and corrosion resistance of the rubber hose, and any decrease in corrosion resistance of the acrylic adhesive can cause yellowing of the rubber hose and surface sticking of plastic rubber, which affects normal use. The way in which toughness is improved by adding an elastomer has conventionally greatly influenced barrier properties and solvent resistance.
Chinese patent CN100548610C discloses that polybutylene terephthalate modified material has improved toughness by adding thermoplastic elastomer and improved solvent resistance by adding epoxy compound and aromatic carbodiimide. The problem with this patent is that the addition of thermoplastic elastomer and epoxy compound improves the compatibility with the glue, reduces the barrier properties of the material, and reduces the resistance to corrosion by the glue.
