Problems solved by technology

Especially for some high-end electronic products, such as rigid plastic shells of tablet computers and smart phones, the currently mainly used thermoplastic elastomer coating materials have not fully met the requirements for its halogen-free flame retardancy, permanent antistatic, and surface wear resistance. , suitable softness, comfortable touch, firm adhesion, permanent pressure change resistance, easy coloring, shock resistance and non-slip, easy processing and molding, and easy recycling. Therefore, the development of high-end environmentally friendly flame-retardant thermoplastic elastomer bags that meet the above requirements Soft material is very important

Embodiment 1

[0045] Example 1: Use 4006# naphthenic oil to premix SEBS-YH502 and SEBS-G1654 as TPE-S, and form the base material with TPU-WHT1185 and TPEE-5526, and use MPP, MCA and OMMT to form a composite flame retardant. Ciba’s P20 is an antistatic agent, and other components are detailed in Example 1 of Table 2. From the test results of Example 1 in Table 3, it can be seen that the prepared TPE composite material is soft and has good mechanical properties. Up to 8.7N / mm, strong adhesion; the test hardness is Shore 86A, the tensile strength is 15.5Mpa, and the elongation at break is 355%; UL94 vertical combustion reaches V-0 level, excellent flame retardant performance, high temperature and high humidity Test: no precipitation; good aging resistance, permanent compression deformation rate is only 28%, surface resistivity is 5.6×10 10 , and good washing resistance, after washing 100 times, it is still 5.3×10 10 ;The surface of the material is smooth and matte, with good wear resistance ...

Embodiment 2

[0046] Example 2: 4006# naphthenic oil was used to premix SEBS-YH502, only SEBS-G1654 was removed, and other components were equal to Example 1. The test results of Example 2 in Table 3: Compared with Example 1, the melt index of the prepared TPE coating material increased slightly, from the original 8.4g / 10min to 9.3g / 10min, and the UL94 flame retardancy was V-0 , Peel strength 8.2N / mm, excellent overall performance.

Embodiment 3

[0047] Example 3: 4006# naphthenic oil was used to premix SEBS-G1654, only SEBS-YH502 was removed, and other components were equal to Example 1. The test results of Example 3 in Table 3: Compared with Example 1 and Example 2, the physical properties of the prepared TPE coating material are basically unchanged, and the overall performance meets the requirements for the use of environmentally friendly TPE flame retardant materials for coating.

Abstract

The invention discloses a TPE flame resistant material for coating plastic and preparing method of the TPE flame resistant material. The TPE flame resistant material is composed of TPE-S, TPO, TPU, TPEE, a composite flame retardant, an antistatic agent, an antioxidant, a compatibilizer, a lubrication release agent and other auxiliaries. The prepared TPE flame resistant material coating plastic is good in fluidity, simple in processing technology, convenient to process and capable of being processed and formed by using an injection molding machine at the temperature between 180 DEG C and 210 DEG C, and production efficiency is high. The processing temperature is lower than 200 DEG C, processing can be conducted at 190 DEG C, energy consumption is lowered due to the low processing temperature, and energy resources are saved.

Description

technical field [0001] The invention relates to a TPE flame-retardant material and a preparation method thereof, in particular to a TPE flame-retardant material for covering plastic casing materials such as PC and ABS of electronics and toy products and a preparation method thereof. Background technique [0002] In recent decades, with the rapid economic development, people have higher and higher requirements for the quality of life. In the application field of polymer materials, especially in many occasions that are in direct contact with human skin, materials are required to have good flexibility, low hardness, wear resistance and comfortable touch. Many rigid plastic products have the surface of Soft materials such as natural or artificial leather, vulcanized rubber, and thermoplastic elastomers are used for covering, and the market space in this field is very large. Especially for some high-end electronic products, such as rigid plastic shells of tablet computers and sm...
