Problems solved by technology

[0004] Its shortcoming lies in the use environment and working function of the air-conditioning outlet assembly, so that the temperature of the air-conditioning outlet assembly is lower than normal temperature when it is working. There is often moisture condensation inside the air-conditioning outlet assembly, and the plastic material is in a wet and cold state. Reduce and absorb water, so that the brittleness of the plastic material increases, resulting in a decrease in the strength of the plastic material, and the air-conditioning outlet assembly is easily damaged when it is compressed or hit. Therefore, a strong air-conditioning outlet suitable for the working environment of the air-conditioning outlet Air outlet assembly

Embodiment 1

[0047] The raw materials of the modified ABS material include the following components in parts by mass: 55-65 parts of ABS, 10-16 parts of shell powder, 2-4 parts of surfactant, 1-3 parts of anti-glass fiber exposure agent TAF, 5- 7 powder, 3-4 parts of flame retardant and 0.2-0.4 parts of graphene. Among them, ABS is a commercially available product, and LG Chem HF-380, HF-381 brand products and Yongxing HI-140, HI-130, HI-121H brand products are selected. Shell powder is a commercially available product with a particle size of 80nm. Sodium dodecylbenzene sulfonate or sodium lignin sulfonate is used as the surfactant, and grinding wheel ash is used as the filler powder, which is a commercially available product at Qinghe Renewable Resources Recycling Station, Pingshan New District, Shenzhen. The flame retardant is DOPO (9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide), which is a commercially available product. Graphene is a commercially available product from Beijing D...

Embodiment 2

[0073] An air-conditioning air outlet assembly, based on the basis of Example 1, the difference is that the raw material flame retardant of the modified ABS material is ODOPB, that is, 10-(2,5-dihydroxyphenyl)-10-hydrogen- 9-oxa-10-phosphaphenanthrene-10-oxide, the amount of flame retardant is the same as the amount of a flame retardant in the embodiment, and the other ingredients in the specific raw material amount are the same as in the first embodiment, based on the modification of the first embodiment The preparation method of the ABS material is to prepare the modified ABS material to obtain the examples 2A-2F corresponding to the examples 1A-1F.

[0074] For the modified ABS materials obtained in Examples 1A-1F and Examples 2A-2F, samples were prepared according to the detection method recorded in the flammability UL94 grade standard and the flame retardancy level of the modified ABS materials was tested. The test results are as follows.

Description

technical field [0001] The invention relates to a vehicle-mounted air conditioner, in particular to a high-strength air-conditioner air outlet assembly. Background technique [0002] The air outlet assembly of the automobile air conditioner is an important part of the automobile air conditioner system, and it is responsible for conveying air conditioning air. The existing air conditioner air outlet assembly is for example the Chinese patent "Automotive Air Conditioner Air Outlet Assembly" whose authorized notification number is CN102620401B, which includes a shell and a blade assembly. [0003] At present, most of the casing and blade components are made of rigid plastics, and the existing rigid plastics include ABS, ABS and alloy plastics. For example, the Chinese patent "A high-performance ABS / ABS alloy material and its preparation method" whose application publication number is CN108219429A discloses a kind of ABS / ABS alloy material, and its raw material formula is as fo...
