Problems solved by technology

However, because polypropylene is a non-polar polymer, the low-temperature performance and aging resistance of homopolymer are also poor, and the molding shrinkage rate is large, which limits the further development and application of polypropylene.

Embodiment Construction

[0022] Below in conjunction with embodiment the present invention is described in detail.

[0023] A kind of super strong super tough polypropylene modified resin, it is made by the raw material of following weight (kg):

[0024]

[0025]

[0026] The modified POE is prepared from the following weight (kg) raw materials: POE140, SBS8, white ointment 2, p-toluenesulfonyl hydrazide 2, tributyltin chloride 2, zinc oxide 4, microencapsulated red Phosphorus 1, di-n-nonyl phthalate 0.5, monoglyceride succinate 1.5, opal powder 5, lanolin 0.3, gum arabic powder 7, antioxidant 6260.8;

[0027] The preparation method of the modified POE is as follows: After mixing the raw materials, put them into the extruder for mixing, and control the temperature of the extruder at 150°C to obtain the extrudate;

[0028] The sub-micron compound modified heavy calcium carbonate is prepared from the following weight (KG) raw materials: heavy calcium carbonate 80, light calcium carbonate 13, carb...

Abstract

The invention discloses a super-strength and super-toughness polypropylene modified resin. The resin is characterized in that the resin is prepared by using the following raw materials, by weight, 100 parts of PP, 4-6 parts of PP-g-MAH, 14-16 parts of modified POE, 0.008-0.01 parts of an antioxidant 1010, 0.005-0.006 parts of an antioxidant DLTP, 0.004-0.006 parts of ZnSt, and 20-25 parts of submicron composite modified heavy calcium carbonate; and in the above formula system, the modified POE has a better compatibility with a PP matrix than EPDM (ethylene-propylene diene monomer) and SBS (styrene butadiene elastomer) as a polyolefin thermoplastic elastomer. The addition of the PP-g-MAH (PP grafted maleic anhydride) further enhances the compatibility with the PP matrix, so the toughness of the obtained blend is greatly improved.

Description

technical field [0001] The invention relates to the field of polypropylene rods, in particular to a super-strength and super-tough polypropylene modified resin and a preparation method thereof. Background technique [0002] Substituting plastic for steel and plastic for wood has become a trend in material development. At present, the materials that mainly replace steel (or copper, alloy) and other metals on the market are mainly engineering plastics such as nylon (PA); nylon (PA) has good toughness, strong wear resistance, oil resistance, shock resistance, tensile and bending strength. . Therefore, it is widely used to process various wear-resistant high-strength parts, instead of copper and alloys as wear-resistant parts of equipment. However, because nylon itself is easy to absorb water, has poor light resistance, poor dimensional stability, and is relatively expensive, it greatly hinders the application range of nylon rods. [0003] As one of the five general-purpose p...
