Performance testing
1. Test method
(1) Flexural modulus: the test speed is 2mm/min according to the standard test of GB/T9341-2008 'determination of plastic bending property'. Wherein the flexural modulus is better when the flexural modulus is more than 1500MPa, the flexural modulus is more than 1300-1500 MPa, and the flexural modulus is worse when the flexural modulus is less than 1300 MPa.
(2) Notched izod impact strength: according to the standard test of GB/T1843-1996 Plastic cantilever beam impact test, type A notch, 23 ℃, 50% humidity. Wherein the impact strength is more than 18kJ/m2Is good, 18 to 10kJ/m2Is generally less than 10kJ/m2Is a difference.
(3) Surface gloss: the ABS material is injected into a square plate by a high-gloss mold, and then the gloss is tested by a surface gloss instrument according to GB/T8807-1988 plastic mirror surface gloss test method at an angle of 60 degrees. Wherein less than 20% is low gloss.
(4) Rockwell hardness: the test samples were 6mm thick discs with a diameter, measured according to GB/T230.1-2004 "Rockwell hardness test method".
(5) Coefficient of dynamic friction: the test was carried out according to ASTM D1894-2014 Standard test methods for static and dynamic coefficients of Friction of Plastic films and sheets. The coefficient of dynamic friction should be controlled to 0.12-0.23, and if too high, a noticeable harshness may result. If it is too low, the smooth feeling is too good, and the soft feeling is hardly masked, so that only the smooth feeling is exhibited.
(6) Skin feel evaluation: the skin feel of the sample is mainly influenced by the dynamic friction coefficient and the Rockwell hardness, and the dynamic friction coefficient is controlled to be 0.12-0.23 and the Rockwell hardness is controlled to be lower than 80 to achieve proper skin feel. Skin feel evaluation was also performed using the tactile panel to verify. The method comprises the following specific steps: the feeling after touching the sample was evaluated by using 5 trained and screened persons as judges of the tactile group, mainly by sliding the finger on the surface of the sample with moderate force. Grade 1 represents smooth and soft touch of the skin, grade 5 represents astringent and hard touch, grade 2-4 represents different grades of change from smooth and soft to astringent and hard, and grade 1-5 sequentially corresponds to best, better, moderate, worse and very poor skin touch. The evaluation results of 5 individuals were averaged, and the average was rounded off as the evaluation result. The skin feel of the present invention is at least moderate and above, i.e., grade 3 and below.
2. Test results
TABLE 3 results of Performance test of each example and comparative example
From the test results in table 3, it can be seen that in examples 1 to 13 of the present invention, by introducing a thermoplastic elastomer having a specific structure into a high-fluidity ABS resin, the soft skin feel of the material can be significantly improved without affecting the mechanical properties. Meanwhile, the lubricant is introduced, so that the dynamic friction coefficient of the material can be obviously reduced, and the material is endowed with smooth skin feeling. The addition of the flatting agent can reduce the surface gloss of the material and avoid bringing a hard plastic feeling in vision. However, from the results of comparative example 1, it is clear that the pure ABS has very poor skin feel effects. Comparative example 2 shows that the mere addition of POE thermoplastic elastomer results in poor compatibility with ABS resin, and consequently poor impact properties. As can be seen from comparative example 3, if the amount of the thermoplastic elastomer is too large, the flexural modulus is poor. Comparative example 4 shows that the material had a large coefficient of dynamic friction without adding a lubricant, and had a harsh feeling, which adversely affected the skin feeling effect. From comparative example 5, it is known that the melt flow rate of ABS is too low, resulting in uneven surface roughness of the material, an increased coefficient of dynamic friction, and an adverse effect on skin feel.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
