Embodiment 1

[0026] Example 1: A transparent reinforced filler masterbatch

[0027] The transparent reinforced filling masterbatch of the present invention is made of polyethylene, transparent glass powder (belonging to non-metallic silicate), polyethylene wax (dispersant) and aluminate (coupling agent) as raw materials, and is processed into granular form by conventional technology. Filler masterbatch or special material.

[0028] The melt index of polyethylene is 1.6-3g / min, and the relative density is 0.90-0.91g / cm 3 Low-density polyethylene or linear low-density polyethylene, choose one of them or use two at the same time according to requirements; SiO2 in transparent glass powder 2 ≥72.8%, Al 2 o 3 ≤2.35%, Na 2 O ≤ 14.58%, CaO ≤ 7.56%; the transparent glass powder is white powder, whiteness ≥ 95%, refractoriness is 650-700 ℃, fineness is 1200-1500 mesh; relative molecular weight of polyethylene wax is 1500- 9500, the relative density is 0.9~0.93g / cm 3 , The softening point is 10...

Embodiment 2

[0031] Embodiment 2: A transparent reinforcing filler masterbatch, which is basically the same as Embodiment 1, and the similarities will not be described again. The difference is:

[0032] The weight percent composition of the transparent reinforcing filler masterbatch of the present invention is as follows: 25% of low-density polyethylene, 65% of transparent glass powder, 7% of polyethylene wax and 3% of aluminate.

Embodiment 3

[0033] Embodiment 3: A transparent reinforcing filler masterbatch, which is basically the same as Embodiment 1, and the similarities will not be described again. The difference is:

[0034] The weight percent composition of the transparent reinforcing filler masterbatch of the present invention is as follows: 15% of low-density polyethylene, 77% of transparent glass powder, 7% of polyethylene wax and 1% of aluminate.

Abstract

The invention discloses a transparent reinforced filling mother stock which comprises the following materials in weight percentage: 10 to 25 percent of polythene, 65 to 85 percent of transparent glass powder, 3 to 7 percent of polyethylene wax and 1-3 percent of aluminic acid ester. The polythene is the low-density or linear low-density polythene, and the transparent glass powder is a nonmetal silicate. The transparent reinforced filling mother stock which has a higher addition level can reduce the contractibility of plastics and the deformation caused by contraction; the transparent reinforced filling mother stock can not only reinforce the rigidity of products but also increase the weight of the products. The filling mother stock has good dispersibility and good solubility with polypropylene and polyethylene. Even a great amount of filler stock is added, the products with good outside fineness can still be obtained. The filling mother stock can not only make the products keep good mechanical properties, but also prolong the service life of the products.

Description

1. Technical field: [0001] The invention relates to a filler masterbatch, in particular to a transparent reinforced filler masterbatch used in the production of various plastic products such as polypropylene and polyethylene. 2. Background technology: [0002] With the rapid development of the plastics industry and the wide application of plastic products, the filling modification technology of plastics has been paid more and more attention by people. Adding various filling materials to plastic products can not only greatly reduce the production cost of the product, but also significantly improve certain properties of plastics, such as mechanical properties, thermal properties, electrical properties, wear resistance and aging resistance, etc. (such as improving Product hardness, increase rigidity, improve heat deformation resistance, adjust gloss, reduce molding shrinkage, improve printing performance, etc.), thus endowing materials with new characteristics to meet the needs...
