Description
Technical Field
The invention relates to the field of polymer composite materials, in particular to a heat-conducting nylon engineering plastic with excellent toughness and a preparation method thereof.
Background
The heat-conducting polymer composite material has the advantages of simple processing and forming, low density, corrosion resistance, good insulating property and the like, and becomes a preferable material for solving the problem of heat dissipation of the LED lamp. With the rapid development of scientific technology, the demand for polymer materials with excellent thermal conductivity is increasing. However, the development of the existing heat-conducting polymer materials still faces many problems, for example, when the filling amount of the existing filling type heat-conducting materials which are researched more intensively is large, the physical and mechanical properties of the materials are obviously reduced, and the materials become seriously brittle, so that the application of the materials is greatly limited.
Magnesium hydroxide [ Mg (OH)2Abbreviated as MH]Belongs to an additive inorganic flame retardant, and compared with the similar inorganic flame retardants, the flame retardant has excellent flame retardant effect on high polymer materialsBesides, the magnesium hydroxide can also inhibit the generation of toxic gases such as smoke, hydrogen halide and the like, namely, the magnesium hydroxide has triple functions of flame retardance, smoke abatement and filling, and has the characteristics of no toxicity, no corrosion and the like. MH has higher decomposition temperature (300-320 ℃), is not easy to decompose at the melting processing temperature of nylon, and is an ideal flame retardant for flame-retardant nylon. The amount added is often very high (typically 60% to 200% of the resin) to achieve a certain flame retardant rating. Because magnesium hydroxide has large polarity and poor compatibility with a base material, the processing performance of the polymer and the mechanical property of the polymer are influenced by high addition amount.

(2) The N- (2-hydroxypropyl) benzene sulfonamide plasticizer does not belong to an environmentally-friendly limited o-benzene plasticizer, and the addition of the plasticizer improves the coating capability of the resin on the powder, and is safe and environmentally-friendly. The hydrogen bonding effect between nylon molecular chains is influenced, and the nylon becomes softer.
(3) The heat-conducting nylon engineering plastic provided by the invention has the advantages that the processing current is reduced by about 20% compared with the normal current due to the addition of the liquid plasticizer, the productivity is improved, the energy is saved, and the cost performance of the product is higher.

Example 2 | 100 | 250 | 2 | 1 | 0 |
Example 3 | 100 | 200 | 10 | 10 | 2 |
Example 4 | 100 | 250 | 10 | 20 | 5 |

Effects of the embodiment
The products obtained in examples 1-4 and comparative examples 1-2 were injection molded to prepare standard test sample strips, and the test results are shown in Table 2.
TABLE 2 Performance test results of examples 1 to 4 and comparative examples 1 to 2
In comparative example 1, a toughening agent is added, no plasticizer is added, and the material has strong rigidity and weak deformability.
In the comparative example 2, the plasticizer is used for replacing the toughening agent, the rigidity of the material is reduced, the elongation at break and the deflection are improved, the heat conductivity coefficient is also higher, and the extrusion current is reduced by 20%.
From examples 1-4, it can be seen that the addition of the toughening agent and the plasticizer greatly reduces the flexural modulus of the material, and the impact strength, the elongation at break and the deflection are all significantly increased, indicating that the ductility of the material becomes better and the deformation resistance is enhanced. The tensile strength of the composite material is always kept above 40MPa, which is higher than that of general plastics (such as polypropylene PP), and the requirement of products such as LED radiators and the like on the strength can be met. In example 3, the addition of the plasticizer reduced the extrusion current by about 10% compared to comparative example 1, but had substantially no effect on the thermal conductivity. The reduction in current means that the material is more fluid, that lower processing temperatures can be used or that a greater capacity is obtained, and is therefore very significant in terms of energy consumption and production efficiency.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
