塑料黑色母粒是一種常用于塑料制品生產(chǎn)中的顏料。它的主要成分是黑色顏料和樹脂基材，可以用于塑料中添加顏色并提高其光澤、耐磨性和耐光性。

一、塑料黑色母粒的用途

塑料黑色母粒的主要用途是塑料制品中添加顏色。在實(shí)際生產(chǎn)中，塑料黑色母?？捎糜诟鞣N注塑、擠出、吹塑和壓延等工藝中，制造黑色塑料制品。常見的黑色塑料制品有黑色桶、黑色管道、黑色家具、黑色汽車配件、黑色手機(jī)殼等等。

二、塑料黑色母粒的生產(chǎn)工藝

塑料黑色母粒的生產(chǎn)工藝主要分為三個(gè)步驟：顏色分散、熱加工和制粒。下面我們將分別介紹這三個(gè)步驟的工藝流程。

顏色分散是將各種顏色顏料分散到樹脂基材中的過程。它是將顏料先在較低的溫度下與樹脂材料混合，并在高速攪拌下達(dá)到良好的顏色分散度。通常，顏料的用量為5%-30%不等。

熱加工是將顏色分散后的原料在高溫高壓下進(jìn)行塑化過程，使其達(dá)到可擠出的狀態(tài)。在這個(gè)步驟中，原料需要經(jīng)過一段時(shí)間的高溫處理，以使顏料在熔融樹脂熔融期間充分分散，從而獲得優(yōu)秀的黑色母粒。

制粒是將塑化后的原料通過磨粉機(jī)或切割機(jī)進(jìn)行切割，得到相對均勻的顆粒，成為黑色母粒。粒徑大小是一個(gè)非常重要的指標(biāo)，通常為2.5mm~3.0mm，在不同的塑料制品加工過程中，顆粒的大小會(huì)產(chǎn)生不同的影響。

三、塑料黑色母粒的性能

良好的著色性能

塑料黑色母粒具有良好的著色性能，其添加量可控制在5%~30%之間，可以滿足大多數(shù)黑色塑料制品的生產(chǎn)需求。

良好的光澤性能

黑色母粒的光澤度高，黑色塑料制品通常具有較高的表面光澤度。

良好的耐磨性能

黑色母粒中的顏料有很高的耐磨性能，所以黑色塑料制品具有較好的耐磨性能，不易劃傷和磨損。

良好的耐光性能

黑色母粒具有良好的耐光性能，可防止黑色塑料制品在陽光下褪色和變黃。

Plastic black masterbatch is a pigment commonly used in the production of plastic products. Its main components are black pigment and resin substrate, which can be used in plastics to add color and improve its luster, abrasion resistance and light resistance.

First, the use of plastic black masterbatch

The main use of plastic black masterbatch is to add color in plastic products. In actual production, plastic black masterbatch can be used in a variety of injection molding, extrusion, blow molding and calendering processes, manufacturing black plastic products. Common black plastic products are black barrels, black pipes, black furniture, black auto parts, black cell phone cases and so on.

Second, the production process of plastic black masterbatch

The production process of black masterbatches is mainly divided into three steps: color dispersion, thermal processing and granulation. Below we will introduce the process flow of these three steps.

Color dispersion is the process of dispersing various color pigments into the resin substrate. It involves mixing the pigments with the resin material at a lower temperature first, and achieving a good color dispersion under high-speed mixing. Usually, the amount of pigment varies from 5% to 30%.

Thermal processing is the process of plasticizing the raw material after color dispersion under high temperature and high pressure to make it reach the extrudable state. In this step, the raw material needs to be processed at high temperature for a period of time in order to fully disperse the pigment during the melting of the molten resin, so as to obtain excellent black color masterbatch.

Pelleting is the process of cutting the plasticized raw material through a mill or cutter to obtain relatively homogeneous particles that become the black masterbatch. The size of the granules is a very important index, usually 2.5mm~3.0mm, and the size of the granules will have different effects in the processing of different plastic products.

Third, the performance of plastic black masterbatches

Good coloring performance

Plastic black masterbatch has good coloring performance, and its additive amount can be controlled between 5% and 30%, which can meet the production needs of most black plastic products.

Good gloss performance

Black masterbatch has high gloss, black plastic products usually have high surface gloss.

Good abrasion resistance

The pigments in black masterbatches have high abrasion resistance, so the black plastic products have good abrasion resistance and are not easy to be scratched and abraded.

Good light resistance

Black masterbatches have good light resistance, which can prevent black plastic products from fading and yellowing under sunlight.
