Description
Technical field
The present invention relates to detection and analysis technical field, talcum powder content analysis and analysis in specially a kind of polypropylene plastics
Method.
Background technology
Decaying total reflection (ATR) is a kind of sample mode of infrared spectrum, is difficult to detect in sample, non-destructive testing and sample
There is advantageous advantage in terms of the acquisition of product surface information.Plastics in process of production, due to additives such as addition color masterbatch, lead to
Translucidus is not often had, therefore conventional projective method sampling is difficult to directly prove effective.The convenience of ATR is mainly reflected in sample
Surface information directly acquires, and sampling efficiency is improved relative to traditional solvent method.
Polypropylene (PP) is a kind of thermoplastic resin made of propylene polymerization, and methyl is arranged in the same side of molecular backbone
Claim isotactic polypropylene, if the chaotic both sides for being arranged in molecular backbone of methyl claim random polypropylene, when methyl is arranged alternately in
The both sides of molecular backbone claim syndiotactic polypropylene.In the acrylic resin of general industry production, isotactic structural content is about 95%,
Remaining is random or syndiotactic polypropylene.Industrial products are using isotactic object as main component.Polypropylene also includes propylene and a small amount of ethylene
Including copolymer.Usually translucent colorless solid is odorless nontoxic.The highly crystallized due to compound with regular structure, therefore fusing point can be high
Up to 167 DEG C.Heat-resisting, corrosion-resistant, product can be its outstanding advantages with moise-heat sterilization.Density is small, is most light general-purpose plastics.Disadvantage
It is that low-temperature impact resistance is poor, it is more easy to aging, but can be overcome respectively by modification.
PP has stronger competitiveness for auto industry, but because its modulus and heat resistance are relatively low, impact strength is poor, because
This cannot be directly used as auto parts machinery, and what is used in car is MODIFIED PP product.Talcum powder is in the row such as medicine, food, makeups
The application of industry is relatively broad.It is then often used in the adjustment of plastics mechanical property in plastic industry, the talcum powder of different content adds
Add, the performance of base material can be influenced in various degree.
Practical content
The purpose of the present invention is to provide talcum powder content analysis and analysis methods in a kind of polypropylene plastics, in solution
State the problem of being proposed in background technology.

(6) from the polypropylene plastics infrared spectrogram that talcum powder content is 5%, 10%, 15%, 20%, 25%, 30%
Determine characteristic peak 1458.10cm-1And 1006.74cm-1Peak height, calculating compares；
(7) matched curve, y=0.369x-1.048 are done according to content and ratio；
(8) polypropylene specimen for scanning unknown talcum powder content, passes through characteristic peak 1458.10cm-1And 1006.74cm-1's
Peak height ratios bring curve into, acquire talcum powder content
Compared with prior art, the beneficial effects of the invention are as follows：
1, in the polypropylene plastics talcum powder content analysis new method, it is easy to operate, it is easy to use, can be rapidly and efficiently
Retrieval PP in talcum powder content；
2 at the same the polypropylene plastics in talcum powder content analysis new method cost it is quick with respect to other analysis modes；
3 and suitable for QC departments carry out typical products in mass production tracking and analysis.
