Embodiment 1

[0025] As shown in Figure 1, put caprolactam into the reactor 1 in sequence, add 2% defoamer and 2% NaOH, start the vacuum pump, start heating after the pressure is lower than 3mmHg, keep the pressure lower than 3mmHg throughout the process and the temperature reaches 108℃~ The melt was refluxed for 20 minutes at 116°C. Stop vacuuming when the uppermost end of the return line is hot. When the melt is heated to 132°C to 134°C, add TDI and stir well, spread the treated metal plate and glass felt (glass cloth or carbon fiber cloth) into the mold in turn, as shown in Figure 1, close the feeding pipe, start the vacuum pump, Vacuum the mold 2, when the pressure is lower than 3mmHg, open the feed pipe, and press the resin into the mold with high-pressure nitrogen at the same time, keep the mold temperature at 150°C-160°C, melt polymerize for 5-30 minutes, cool and demould Get products.

Embodiment 2

[0027] As shown in Figure 1, put caprolactam, 10% nylon 1212, 2% defoamer and 2% NaOH into the reactor in turn, start the vacuum pump, start heating after the pressure is lower than 3mmHg, keep the pressure lower than 3mmHg in the whole process and When the temperature reaches 160°C-200°C, keep the melt boiling until the nylon 1212 is completely dissolved, then add TDI into the reaction kettle and stir well. Lay the treated metal plate and glass mat (glass cloth or carbon fiber cloth) into the mold in turn, as shown in Figure 1, close the feeding pipe, start the vacuum pump, and vacuum the mold. After the pressure is lower than 3mmHg, open the feeding pipe, and at the same time Use high-pressure nitrogen to press the resin in the reaction kettle into the mold, keep the mold temperature at 160°C-200°C, melt polymerize for 5-30 minutes, cool and demould to obtain the product.

Embodiment 3

[0029] As shown in Figure 1, put caprolactam, 10% nylon 66, 2% defoamer and 2% NaOH into the reaction kettle in turn, start the vacuum pump, start heating after the pressure is lower than 3mmHg, maintain the whole process pressure below 3mmHg and When the temperature reaches 160°C-200°C, keep the melt boiling until the nylon 66 is completely dissolved, then add TDI into the reaction kettle and stir well. Lay the treated metal plate and glass mat (glass cloth or carbon fiber cloth) into the mold in turn, as shown in Figure 1, close the feeding pipe, start the vacuum pump, and vacuum the mold. After the pressure is lower than 3mmHg, open the feeding pipe, and at the same time Use high-pressure nitrogen to press the resin in the reaction kettle into the mold, keep the mold temperature at 160°C-200°C, melt polymerize for 5-30 minutes, cool and demould to obtain the product.

Abstract

The present invention relates to a continuous fiber reinforcing nylon and a metal parts preparation method. The method is that: a processed metal plate is placed at the bottom of a mold, the fiber with the same area with the metal plate is placed on the top of the metal plate; the mold is sealed and heated to the required temperature for the reacting of a monomer; the dehydrated caprolactam liquid is melted in the vacuum, or proper plasticizer is added into the vacuum, which is heated to a given temperature to be melted and mixed to get the mixed liquid. The mixed liquid is poured into the mold at certain temperature and kept reacting for 5 to 30 minutes, then the temperature is reduced, the mold is stripped, and the product is gained. Compared with the prior art, the present invention has the advantages of simple in technique, convenient and good interface mixing of the fiber and interface of the body.

Description

technical field [0001] The invention relates to a method for compounding fiber-reinforced nylon and metal materials to prepare composite material parts. In the method, nylon 6 monomer is polymerized in situ on the metal surface, and a composite product of nylon 6 and metal is formed at one time. Background technique [0002] Cast nylon (MC nylon) material is generally monomer caprolactam, which is made by vacuum dehydration and heating reaction molding. It has low polymerization temperature, simple process, high crystallinity, large molecular weight, wear resistance, self-lubrication, and service temperature range. Wider and other characteristics, it is an ideal substitute material for non-ferrous metals such as copper and aluminum, but compared with metal materials, it has the disadvantages of poor toughness and low impact strength. [0003] There are three main ways to solve the problem of poor toughness: the first is to add a plasticizer; the second is to develop a new c...
