Problems solved by technology

During the production, storage, transportation and use of these craft products, they are affected by external environmental factors, which will lead to unexpected damage effects
On the one hand: the product is subject to collision, scratch, surface layer peeling, peeling, etc., and is affected by natural water, light, heat and oxygen and artificial household cleaning during use, and the thin surface layer of the product is affected by aging. and damage, which seriously affects the appearance of the product and the effect of imitating natural wood grain and marble, shortening the service life of the product
On the other hand: the production process of such products is complicated, and it is necessary to increase the production equipment of spraying, printing, pasting, and laminating. Long, large investment, high cost, and flammable and explosive chemical solvents are used in the secondary processing process, which pollutes the environment and affects the ecology
The price of the recently launched two-color machine is relatively high, and the wood grain / marble effect product formed at one time can solve the above problems, but the disadvantage is that the wood grain and cloud (grain) stone effect of the product is poor, vulgar and single, the feeling is very bad, and the product grade is not high. , and new production equipment and costs will be added
The above unfavorable factors have inhibited the application and development of plastic products

Embodiment 1

[0032] Embodiment 1: the selection of polyolefin imitation natural multifunctional color masterbatch carrier resin

[0033] The basic resin (B) selects polypropylene as the research object, that is, determines that polypropylene is the B resin. According to the characteristic performance parameters of polypropylene B, polypropylene resin A is selected, and the best resin X is selected among resin varieties that can be alloyed with PP, such as polyester PBT, PET, polycarbonate PC and nylon PA. Black and white stripes are selected as the research objects for the color stripes, and the raw materials and content percentages of the screening experiments are shown in Table 2.

[0034] Table 2: Screening Example Formulations for Resin X (PP)

[0035]

[0036] According to the selected raw materials, the best resin X is screened with the examples, and the formula of the screening examples is shown in Table 2. According to the formula shown in Table 2, two kinds of bla...

Embodiment 2

[0041] Embodiment 2: the selection of the imitation natural multifunctional color masterbatch carrier resin of ABS

[0042] In ABS plastic products, ABS resin is first selected as A resin. According to the characteristic performance parameters of the two kinds of ABS resins A and B, it is planned to screen the best resin X among resin varieties such as polycarbonate (PC) and polyester PET that can be alloyed with ABS. Black and white stripes were selected as the research objects for color stripes, and the screening experimental formula is shown in Table 4.

[0043] Table 4: Screening Formulation for Resin X (ABS)

[0044]

[0045] According to the formula shown in Table 4, two black masterbatches and two white masterbatches were successively prepared. Add the four kinds of masterbatches to ABS resin (B resin) at a ratio of 1%, adjust the injection molding temperature to 210-235°C, and reasonably adjust the injection molding process and back pressure to obta...

Embodiment 4

[0063] Embodiment 4: the production of monochrome masterbatch

[0064] In view of the multi-color pattern structure and multi-functional requirements of the six swatches formulated, several single-color masterbatches must be manufactured in advance. Six kinds of single-color masterbatch production formulas shown in Table 8:

[0065] Table 8: Six single-color masterbatch formulations:

[0066]

[0067] According to the formula shown in Table 8, six kinds of single-color masterbatches were successively prepared. Taking polypropylene and ABS products as an example, add six kinds of masterbatches to polypropylene PP700 or ABS757 (B resin) at a ratio of about 1%, and adjust the injection temperature to 190-210°C for polypropylene and 210-235°C for ABS. Six kinds of cloud (grain) products were obtained by injection molding process and back pressure. The characteristic properties and swatch effects of the six monochrome masterbatches are shown in Table 9. ...

Abstract

The present invention features that the color concentrate is prepared with main carrier resin A, matched carrier resin X, compatizer, pigment, inorganic stuffing, antistatic agent, light stabilizer, antioxidant and pigment lubricating dispersant. The main carrier resin an and the matched carrier resin X, which has obviously different compatibility and smelting behavior from that of the basic resin B in the product, may constitute alloy carrier resin. The said materials may be altered to result in various decoration effects.

Description

technical field [0001] The invention relates to a natural imitation multifunctional color masterbatch and its application. The feature is that it can use plastic injection molding to imitate cloud (grain) stone, marble color, and extrude imitation natural effects such as imitation wood grain. The invention belongs to the technical field of synthetic imitation natural materials. Background technique [0002] As the fourth largest material after steel, wood, and cement, synthetic polymer materials are widely used in industries such as electronics, construction, and automobiles. Especially in industries involving human daily life, travel, and entertainment, more and more synthetic polymer materials are used. The pursuit of nature and returning to basics makes consumers not only need the direct use performance of synthetic material products, but also require the appearance of products to meet their tactile and visual needs, and require the appearance of synthetic material prod...
