Embodiment 1

[0088] Example 1 (20% by weight of the wear-resistant layer + 40% by weight of the reinforcement layer + 40% by weight of the toughened layer):

[0089] (1) Weigh 320 kg of caprolactam raw materials, add them to the melting tank, and heat until they are completely melted.

[0090] (2) The temperature is raised to 125°C, 0.9 kg of sodium methoxide is added, the stirring device is turned on, the dehydration device is turned on, and the dehydration is performed for 40 minutes to complete dehydration to obtain activated caprolactam.

[0091] (3) Transfer 64kg of activated caprolactam to 1# reaction tank, add 5.12kg of polyethylene glycol lubricating grease, continue dehydration, stir and heat to 140°C.

[0092] (4) Transfer 128kg of activated caprolactam to 2# reaction tank, add 19.2kg of poly(butyl acrylate-styrene) whiskers, continue dehydration, stir and heat to 140°C.

[0093] (5) Transfer 128kg of activated caprolactam to 3# reaction tank, add 19.2kg of EVA-g-MAH, continue dehydration,...

Embodiment 2

[0099] Example 2 (30% by weight of the wear-resistant layer + 20% by weight of the toughened layer + 50% by weight of the reinforced layer):

[0100] (1) Weigh 100 kg of caprolactam raw materials, add them to the melting tank, and heat until they are completely melted.

[0101] (2) The temperature is raised to 120°C, 0.4 kg of sodium methoxide is added, the stirring device is turned on, and the dehydration device is turned on, and dehydrated for 30 minutes to complete dehydration to obtain activated caprolactam.

[0102] (3) Transfer 50kg of activated caprolactam to 1# reaction tank, add 5kg of potassium polytitanate whiskers, continue dehydration, stir and heat to 135°C.

[0103] (4) Transfer 20kg of activated caprolactam to 2# reaction tank, add 2kg of EVA-g-MAH, continue dehydration, stir and heat to 135°C.

[0104] (5) Transfer 30kg of activated caprolactam to 3# reaction tank, add 1.5kg of polyolefin base lubricating grease, continue dehydration, stir and heat to 135°C.

Embodiment 3

[0111] Example 3 provides a multilayer modified cast nylon board, which is made of the multilayer modified cast nylon of the present invention. figure 1 Show the cross-sectional view of the nylon plate, such as figure 1 As shown, the layers of the multilayer nylon board are toughened layer 1, reinforced layer 2, and wear-resistant layer 3 in sequence.

[0112] The middle layer of the multi-layer nylon board is reinforced layer 2, which has high mechanical strength, one side surface layer is toughened layer 1, which has high impact resistance, and the other side surface layer is wear-resistant layer 3, which has High anti-wear performance. The multi-layer modified composite nylon board has a reinforced matrix, abrasion resistance on one side and impact resistance on one side, and can be applied to various complicated working environments.

Abstract

The invention relates to a multilayer modified casting nylon material. The multilayer modified casting nylon material comprises at least two of an anti-abrasion layer, a toughening layer and a reinforcing layer. The anti-abrasion layer is made of anti-abrasion casting nylon. The toughing layer is made of toughening casting nylon. The reinforcing layer is made of reinforced casting nylon. The multilayer modified casting nylon material has different properties on different levels and can meet the requirements of different use positions of parts for different properties.

Description

Technical field [0001] The invention relates to the field of polymer materials, in particular to a multilayer modified cast nylon material and a preparation method thereof. Background technique [0002] With the development of the chemical industry and machinery industry, the amount of engineering plastics such as nylon is increasing in national construction and production. Some key metal parts are gradually replaced by low-density, high-performance, and low-price nylon material parts to improve product performance. The increase in weight and cost have been greatly reduced, thus promoting the rapid development of "plastics instead of steel". [0003] Cast nylon, also known as MC nylon or monomer cast nylon, the English name is MonomerCast Nylon. Casting nylon is obtained by using the molten raw material caprolactam monomer as a catalyst with an alkaline substance, together with an activator and other additives, and directly injecting it into a preheated mold. The material is obtai...
