First, technical field:
The present invention relates to glass fibre manufacturing technology field, be specifically to provide it is a kind of strengthen PP (polypropylene) or
PBT (polybutylene terephthalate (PBT)) alkali-free glass fibre rove sizes.
2nd, background technology:
PP composite reinforced by glass and enhancing PBT composite are widely used in engineering field, wherein strengthening
PP composites due to being substantially better than other conventional engineering plastics on sexual valence, meanwhile, the introducing of glass fibre is to PP composite woods
Every mechanical property of material has a huge impact, such as:High tensile strength, bending modulus is higher, and heat-resisting quantity is more preferable etc..Closely
Glass fiber reinforcement PP materials apply increasing in household electrical appliance, auto industry, building industry over a little years, to glass fibre
Demand also grow with each passing day.Glass fiber reinforcement PBT composite has outstanding heat resistance, long-term ageing and fire-retardant because of it
Performance, can be applicable to include automobile, electronic/electrical device, machinery industry:Home appliances (food processing blade, vacuum cleaner element,
Electric fan, Hair drier housing, coffee vessel etc.);Electric elements (press by switch, motor casing, fuse box, computer keyboard
Key etc.);Auto industry (radiator lattice window, body panel, wheel cover, door and window part etc.).Both the above composite is all fortune
With one of most commonly used composite, it popularizes the application that scope is even more than nylon products.But because PP and PBT resin exist
Generally in the range of extrusion design temperature, resin viscosity is low, due to close non-newtonian fluid, there is the characteristic of shear shinning, shearing speed
Rate is higher, and viscosity is lower, particularly PP resins, more sensitive to shear rate.When industrialized production rove strengthens PP and PBT
All easily there is glass fibre and shear problem bad, that dispersion is irregular, i.e., so-called " glass fibre does not melt ".Therefore, develop a kind of
Not only well but also glass fibre can be made to be easy to the size sheared to improve the production performance of glass fibre with PP and PBT resin compatibility
It is very necessary with mechanical property.Need to meet shearing requirement, while also needing to meet following general performance requirement (glass fibre
30%) content is:
Tensile property (according to ISO527 method of testings)
Resin | PP | PBT |
Tensile strength | ≥80 | ≥120 |
Cutting performance (shears the method for testing of dispersive property, the patent No. according to a kind of-glass fibre in thermoplastic
ZL201410286033.7)
Resin | PP | PBT |
Cutting performance | It is good | It is good |
For this reason, it may be necessary to pass through to develop a kind of new size:Can possess excellent compatibility with target resin, with full
The index request of sufficient mechanical performance, and with good cutting performance so that it is good using smoothness.
3rd, the content of the invention:
It is an object of the invention to provide a kind of strengthen PP or PBT alkali-free glass fibre rove sizes, the size
Not only with PP and PBT resin compatibility well but also can make glass fibre be easy to shearing, both can guarantee that the mechanical property of final composite,
The process of roving enhancing PP and PBT can be made smooth again.
To solve the above problems, the present invention is adopted the following technical scheme that:
