Description
Technical Field
The invention relates to the technical field of compositions of high molecular compounds, in particular to a red nylon composite material and a preparation method and application thereof.
Background
PA6 has excellent mechanical strength, rigidity, mechanical shock absorption, wear resistance, electrical insulation and chemical corrosion resistance, is generally used for products such as automobile parts, mechanical parts, electronic and electric products, engineering accessories and the like, has different requirements on nylon materials in different application fields, and particularly has increasingly diversified color requirements on materials in garden tools and industrial electronic products, and particularly has red color with striking characteristics, and is widely applied to the two products. The appearance color of the nylon product is mainly determined by the toner or pigment in the nylon composite material, and the common red toner mainly comprises naphthalenone red, cerium sulfide, fuchsin and the like, but the color brightness and the coloring stability of the toner after being mixed with nylon resin have different degrees of problems.
At present, the problems are mainly solved by developing a new pigment or improving a formula of a nylon composition, for example, the prior art discloses a red reactive dye suitable for nylon dyeing and a preparation method thereof, wherein (m) -beta-hydroxyethyl sulfone sulfate aniline and cyanuric chloride are subjected to condensation reaction to obtain a primary condensation liquid, and H acid is added to obtain a secondary condensation liquid; meanwhile, adding 3- (hydroxyethylamino sulfonyl) -4-chloroaniline into an acid solution and carrying out diazotization reaction on the acid solution and the sodium nitrite solution to obtain diazonium solution; and then coupling reaction is carried out on the secondary condensation liquid and the diazonium liquid to obtain a coupling reaction liquid, and then hydrolysis reaction is carried out on the coupling reaction liquid to obtain the red reactive dye which is bright in luster and good in colorability.
For another example, the prior art discloses a red cast nylon material and a preparation method thereof, and the red cast nylon material comprises the following raw materials in parts by weight: 98.6 to 98 portions of polyamide resin, 0.25 to 0.35 portion of active yellow, 0.6 to 0.8 portion of fuchsin, 0.15 to 0.25 portion of activator and 0.4 to 0.6 portion of catalyst promoter, and the red cast nylon material provided by the invention has the advantages of higher tensile strength, bending strength, good wear resistance, dimensional stability and the like through grouping ingredients and step-by-step activation technology.
However, the processing temperature of the conventional nylon product is high, and the nylon composite material has poor color stability due to the fact that the nylon composite material is easy to absorb water. In order to solve the problem, the prior art discloses nylon with high color stability and a preparation method thereof, wherein 63-65 parts of PA6 resin, 30-35 parts of glass fiber, 0.1-0.2 part of antioxidant, 0.25-0.35 part of nucleating agent and 0.45-0.55 part of lubricant, the nylon also comprises pigment, the pigment comprises 0.25-0.35 part of white powder, 0.2-0.4 part of red powder A and 0.2-0.4 part of red powder B, the red powder B comprises cerium sulfide, and the product is modified by taking cerium sulfide with specific content as pigment, so that the obtained nylon is firmly colored, and the color change condition of the nylon after moisture absorption is remarkably improved; however, the vividness of the red toner is insufficient, and the nylon composite material has poor weather resistance due to fluorescence.
Disclosure of Invention
The invention aims to overcome the defect and the defect that the existing nylon composite materials with various colors are difficult to have good weather resistance and vividness at the same time, and provides a red nylon composite material.
The invention further aims at providing a preparation method of the red nylon composite material.
It is still another object of the present invention to provide the use of the above red nylon composite in the preparation of gardening tools or industrial electronics.
The invention provides a garden tool part made of the red nylon composite material.
The above object of the present invention is achieved by the following technical scheme:
the invention discloses a red nylon composite material, which comprises the following components in parts by weight:
the toner is bis (p-chlorophenyl) -1, 4-diketopyrrolopyrrole;
the nucleating agent is linear saturated carboxylate and/or sand resin with carbon chain length more than or equal to C28;
the viscosity of the nylon resin is less than 3.3 measured according to GB/T38138-2019 standard.
The red nylon composite material disclosed by the invention has the advantages that nylon resin with specific viscosity is taken as a matrix to be combined with toner bis (p-chlorophenyl) -1, 4-diketopyrrolopyrrole (DPP red), so that the dispersion uniformity of the bis (p-chlorophenyl) -1, 4-diketopyrrolopyrrole (DPP red) in the nylon resin is improved, the coloring uniformity is improved, and the nylon resin is converted into heterogeneous nucleation from the original homogeneous nucleation by matching with a specific type of nucleating agent, so that the crystallization speed of the nylon resin is accelerated, and the three interact, so that the weather resistance of the composite material is improved while the good brightness is maintained. When the viscosity of the nylon resin is too high, a large amount of heat is generated in the melt shearing process to cause the decomposition of bis (p-chlorophenyl) -1.4-diketopyrrolopyrrole (DPP red), a large amount of black spots are generated while the bright red is reduced, the appearance is influenced, and unstable substances are generated after the decomposition of the bis (p-chlorophenyl) -1.4-diketopyrrolopyrrole (DPP red), so that the weather resistance of the composite material is influenced.
In a specific embodiment, the nylon resin is aliphatic nylon resin (such as PA6 and PA 66), and the viscosity of the nylon resin can be measured by using GB/T38138-2019 standard; optionally, the viscosity of the nylon resin is 2.4-2.8 and 2.5-2.7.
Optionally, the nucleating agent is linear saturated carboxylic acid sodium salt and/or carboxylic acid calcium salt with carbon chain length more than or equal to C28. Preferably, the nucleating agent is a linear saturated carboxylic acid sodium salt having a carbon chain length of C28-C32; specifically, the nucleating agent LICOMONT NAV101 PWD may be selected.
Preferably, the toner is 0.45 to 0.55 parts by weight. When the addition amount of the toner is 0.45-0.55 weight parts, the red nylon composite material has better vividness and weather resistance. Alternatively, the toner is 0.45 to 0.5 parts by weight, or the toner is 0.5 to 0.55 parts by weight.
Optionally, the antioxidant is one or more of phenolic antioxidants and phosphite antioxidants.
In a specific embodiment, the antioxidant of the present invention may be one or more of antioxidant 1010, antioxidant 1076, antioxidant 168 and antioxidant 2246.
The preparation method of the red nylon composite material comprises the following steps:
the nylon resin, the antioxidant, the nucleating agent and the toner are uniformly mixed, then the mixture is added into a double-screw extruder at a feeding speed of 230-250 kg/h, and the mixture is melt blended, extruded and granulated at the temperature of 210-240 ℃ to obtain the red nylon composite material.
When the feeding speed is low, bis (p-chlorophenyl) -1, 4-diketopyrrolopyrrole (DPP red) is easy to decompose, so that the vividness and weather resistance of the nylon composite material are reduced; when the feeding speed is high, the nylon composite material is plasticized poorly, so that the toner is unevenly dispersed in the nylon resin matrix, and toner points are generated. When the extrusion temperature is low, the nylon resin and the components such as the antioxidant, the nucleating agent and the like cannot be fully fused; and when the extrusion temperature is high, the decomposition of bis (p-chlorophenyl) -1, 4-diketopyrrolopyrrole (DPP red) is also caused.
Preferably, the temperature of the melt blending extrusion is 220-230 ℃.
The invention also protects the application of the red nylon composite material in preparing garden tools or industrial electronic products.
The garden tool part prepared from the red nylon composite material is also within the protection scope of the invention.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a red nylon composite material, which is characterized in that nylon resin with specific viscosity is taken as a matrix to be combined with toner bis (p-chlorophenyl) -1, 4-diketopyrrolopyrrole to improve the dispersion uniformity of the toner in the nylon resin so as to improve the coloring uniformity, and a specific nucleating agent is matched to convert the original homogeneous nucleation of the nylon resin into heterogeneous nucleation, so that the crystallization speed of the nylon resin is accelerated, and the three interact, thereby improving the weather resistance of the composite material while keeping good brightness.

Wherein, the rotating speed of the double-screw extruder is 240r/min, and the length-diameter ratio is 42-48.
3. Performance testing
(1) Vividness assessment
After the red nylon composite materials of the examples and the comparative examples are dried in a blast oven at 100 ℃ for 4 hours, an injection molding machine is adopted to carry out injection molding for 30 seconds at 260 ℃ to obtain a smooth color plate with 83mm 54mm 2mm size and no dermatoglyph on the surface, then an X-rite7000A color difference meter is used to measure an A value under a D65 light source, and the larger the A value is, the better the vividness of the material is indicated.
(2) Weather resistance test
After the red nylon composite materials of the examples and the comparative examples were dried in a forced air oven at 80 ℃ for 4 hours, smooth panels with no skin lines on the surfaces were injection molded using an injection molding machine at 83mm 54mm 2mm, and the injection molding conditions were that the materials remained at 240 ℃ for 30s.
The test was carried out in a UVA-340 test box as specified in GB/T16422.3-2004 for a total of 72h for 6 cycles with 8h drying+4 h condensation to 1 cycle. The data of the color plate under the D65 light source is measured by an X-rite7000A color difference meter before and after the color plate is put into a UVA-340 test box, the color difference before and after the comparison is represented by delta E, and the larger delta E represents the poorer weather resistance.

The results of the performance test on the red nylon composite in each of the examples and comparative examples according to the above-mentioned method are shown in table 3.
Table 3 test results for each of examples and comparative examples
| Numbering device | Weather resistance (delta E) | Vividness (A value) |
| Example 1 | 1.7 | 49.0 |
| Example 2 | 1.2 | 50.0 |
| Example 3 | 1.6 | 48.0 |
| Example 4 | 1.7 | 47.1 |
| Example 5 | 2.0 | 49.1 |
| Example 6 | 1.9 | 48.1 |
| Example 7 | 1.6 | 48.1 |
| Example 8 | 1.7 | 49.1 |
| Example 9 | 1.8 | 49.1 |
| Comparative example 1 | 2.4 | 49.0 |
| Comparative example 2 | 2.5 | 45.9 |
| Comparative example 3 | 2.5 | 45.9 |
| Comparative example 4 | 2.3 | 49.1 |
| Comparative example 5 | 2.5 | 48.1 |
| Comparative example 6 | 2.7 | 46.5 |
The vividness of the red nylon composite material reaches 47.1-50, the weather resistance delta E reaches 1.2-2.0, meanwhile, as can be seen from examples 1-3 and comparative example 6, the viscosity of the nylon resin has an effect on the weather resistance and vividness of the red nylon composite material, when the viscosity of the nylon resin is too high, a large amount of heat is generated in the melt shearing process to cause the decomposition of bis (p-chlorophenyl) -1.4-diketopyrrolopyrrole (DPP red), the vividness of red is reduced, meanwhile, unstable substances are generated after the decomposition of the bis (p-chlorophenyl) -1.4-diketopyrrolopyrrole (DPP red), and the weather resistance of the red nylon composite material is further reduced.
From examples 2, 4, 9 and 1, it was found that a specific kind of nucleating agent was required to be selected to effectively improve the weatherability of the red nylon composite while maintaining the vividness thereof, and that sodium carboxylate nucleating agent and sand resin nucleating agent were preferable.
It can be found from examples 2, 5, 6, 7 and 8 that the amount of bis (p-chlorophenyl) -1.4-diketopyrrolopyrrole (DPP red) also causes vividness and weather resistance of the red nylon composite, and is more advantageous to improve vividness and weather resistance at the same time when the amount of bis (p-chlorophenyl) -1.4-diketopyrrolopyrrole (DPP red) is added in an amount of 0.45 to 0.55 parts by weight.
