Description
Technical field
The present invention relates to a kind of method that high-polarity polypropylene resin material is prepared in Rhizoma Seu Herba Bergeniae modification, belong to acrylic resin
Technical field of material.
Background technology
Polypropylene, is a kind of thermoplastic resin prepared by propylene polymerization.The highly crystallized in compound with regular structure, thus molten
Point may be up to 167 DEG C.Heat-resisting, corrosion-resistant, the sterilization of goods used vapour is its outstanding advantages.Density is little, is the lightest general plastic
Material.Shortcoming is that low-temperature impact resistance is poor, and electrostatic degree is high, contacts the most aging with copper, and dyeability, printing and adhesion are poor.Poly-third
Alkene is polymer nontoxic, that odorless, tasteless milky are highly crystalline, and density only has 0.90～0.91g/cm3, it is the most all moulding
One of kind the lightest in material.It is particularly stable to water, and the water absorption rate in water is only 0.01%, molecular weight about 80,000～150,000.
Good moldability, but because shrinkage factor is big (being 1%～2.5%).Thick article easily caves in, part higher to some dimensional accuracies, is difficult to
In reaching requirement.Therefore needing it modified, the method to its modification has blending and modifying and cross-linking modified method at present, and PA, ABS etc. are firm
Property polymer and PP intensity and the rigidity that then can toughness reinforcing while ensure material is blended.But due to this kind of rigid polymer
Being all polar polymer, and PP material is non-polar material, surface can be low so that it is both compatibilitys are poor, is difficult to infiltration, bonding
With printing, paintability is poor.Polyacrylic cross-linking modified during degraded and cross-linking reaction exist simultaneously, use crosslinking with radiation time
Cross-linking efficiency ratio is relatively low, and is typically all when using chemical crosslinking and promotes to hand over the cross-linking system that helps of unsaturated bond by addition
Connection reaction.
Summary of the invention
The technical problem to be solved: prepare polyacrylic resin material for blending modification method, due to polypropylene
Material is non-polar material, and surface can be low so that poor with PA, ABS compatibility, is difficult to infiltration, bonds and print, paintability
The drawback of difference, it is provided that one takes the mixing such as peptone, potassium phosphate, prepares Selective agar medium after high temperature sterilize, the yellow bar of inoculation
