Description
Technical Field
The invention relates to the technical field of new high-molecular materials, in particular to semi-aromatic polyamide and a molding composition composed of the semi-aromatic polyamide.
Background
The polyamide has good comprehensive properties including mechanical property, heat resistance, abrasion resistance, chemical resistance and self-lubricity, low friction coefficient, certain flame retardance, easy processing and the like, and is widely suitable for being filled, reinforced and modified by glass fibers and other fillers, so that the performance is improved and the application range is expanded. Semi-aromatic polyamides have been developed in recent years with great emphasis on their superior heat resistance and mechanical properties.
However, the synthetic raw materials of the existing polyamide resins are mainly derived from petroleum cracked products. The petroleum-based polyamide contains some chemically unstable substances, and the substances are easy to generate chemical changes when contacting a high-temperature heat source in the production process, so that the color of the resin is deteriorated and the mechanical properties are lost. Under the conditions of long-time sunshine and long-time heating, the related products are easy to generate phenomena of yellowing, aging and the like, and the appearance and the quality of the products are greatly influenced.
Prior patent application 201710955052.8 discloses that the whiteness of polyamide materials can be increased by increasing the biobased content of the polyamide, with good colour levels. However, this can only improve the color developability by increasing the whiteness of the resin itself, and does not improve the color developability from the degree of binding between the polyamide resin matrix and the pigment. Meanwhile, only improving the whiteness and the anti-yellowing effect of the polyamide cannot obtain a polyamide product with good color.
Factors influencing the coloring property of the bio-based semi-aromatic polyamide are mainly factors such as interaction force between the pigment and the resin and dispersion uniformity of the pigment in the resin matrix. Therefore, the main factor affecting the colorability is the resin matrix itself.
Disclosure of Invention
The purpose of the present invention is to provide a semi-aromatic polyamide having an advantage of good colorability.
It is another object of the present invention to provide a polyamide molding composition comprising the above semi-aromatic polyamide, which can maintain good colorability.
The invention is realized by the following technical scheme:

Preferably, the semi-aromatic polyamide has an amino group content of 30 to 60 mol/ton and a carboxyl group content of 50 to 80 mol/ton.
The bio-based polyamide contains fewer chemically unstable substances, and the acting force between the pigment and the resin is less influenced; the proper concentration of the end group can also help the pigment enter molecular chains and improve the dispersibility of the pigment. The pigment is easier to disperse in the resin matrix by regulating the content of the bio-based groups, the proportion of the repeating units, the concentration of the end groups and the selection of the monomers, thereby improving the tinting strength of the pigment. Within the preferred range, the coloring property is better.

The relative colorability was determined to be 100% based on the colorability of comparative example 1.
From comparative example 1/2 and example 12, it is understood that even though the molar ratio of each monomer and the content of terminal groups are within the range of the present invention, the biobased content is low and the improvement in the coloring property is limited, the improvement is remarkable when the biobased content is higher than 39 mol%.
From comparative example 3/4, it is understood that the content of terminal groups is outside the range of the present invention and the improvement of colorability is limited.
As can be seen from comparative example 7, when neither the biobased content nor the terminal group content was within the range of the present invention, the coloring property was even worse.
It can be seen from the comprehensive comparison example that in order to achieve the increase of the relative tinting strength, according to the technical scheme of the invention, the molar ratio of each monomer, the content of the terminal amino group and the content of the bio-group are required to reach the range of the invention.
The proportions of the components of the molding compositions of example 5 and comparative example 1/4/6/7, which are composed of polyamide resin, and the preparation method are as follows: 100 parts of polyamide resin; 30 parts of talc; and 15 parts of nitrile rubber.
Method for producing a polyamide molding composition: according to the formula, polyamide resin, talc and butadiene acrylonitrile rubber are uniformly mixed in a high-speed mixer, then the mixture is added into a double-screw extruder through a main feeding port, and a reinforcing filler is fed laterally through a lateral feeding scale, extruded, cooled by water, granulated and dried to obtain the polyamide molding composition.
