Problems solved by technology

Toughening modification can be divided into elastomer modification and non-elastomer modification. At present, elastomer modification is generally used in China. The most used modifiers are CPE and ACR. Adding a sufficient amount of impact modifier, generally All of them can achieve almost ideal toughening effect, but the amount of impact modifier will lead to a decline in the performance indicators such as tensile strength, weld angle strength, bending strength, and Vicat softening point of the profile. Therefore, The increase in the amount of elastomer modifier is at the expense of the strength and rigidity of the material, and the cost will also increase

Embodiment 1

[0010] The manufacturing method of a toughened profile described in this embodiment includes the use of PVC resin material, which is characterized in that inorganic rigid particles after surface shock grinding treatment and coupling agent treatment are added to the PVC resin material. Particles and PVC resin materials are blended and extruded. When mixing, the temperature of the hot roll is set to 105 degrees Celsius, and the temperature of the cold roll is set to 60 degrees Celsius, so that the inorganic rigid particles are fully mixed with PVC to produce a certain image interface. In the extrusion production line Above, the cooling water temperature can be controlled constantly.

[0011] The inorganic rigid particles can be nano-calcium carbonate or nano-silicon dioxide. After the nano-calcium carbonate or nano-silicon dioxide is subjected to surface shock grinding and coupling agent treatment, it is fully mixed with PVC resin and extruded. , shaping, cooling, pulling, cutti...

Abstract

The present invention discloses a manufacture method for a toughened profile. The method comprises adopting a PVC resin material. The method is characterized in that: the PVC resin material is added with inorganic rigid particles, wherein the inorganic rigid particles are subjected to a surface vibrating and grinding treatment, and are further treated by a coupling agent; the inorganic rigid particles and the PVC resin material are blended and extruded, wherein the hot roll temperature is set to 105 DEG C and the cold roll temperature is set to 60 DEG C during the material blending process, such that the inorganic rigid particles and the PVC resin material are completely and uniformly mixed to generate a certain phase interface, and then are extruded. The manufacture method of the present invention adopts the inorganic rigid nano-particles to toughen the PVC profiled bar, such that the product has characteristics of excellent toughening and strengthening property, excellent aging resistance, good stability and large rigidity, and the cost of the formula is reduced.

Description

technical field [0001] The invention relates to a modified PVC material, in particular to a method for manufacturing a toughened profile. Background technique [0002] In rigid PVC profiles, the toughening modification is mainly through impact modifiers. Toughening modification can be divided into elastomer modification and non-elastomer modification. At present, elastomer modification is generally used in China. The most used modifiers are CPE and ACR. Adding a sufficient amount of impact modifier, generally All of them can achieve almost ideal toughening effect, but the amount of impact modifier will lead to a decline in the performance indicators such as tensile strength, weld angle strength, bending strength, and Vicat softening point of the profile. Therefore, The increase in the amount of elastomer modifier is at the expense of the strength and rigidity of the material, and the cost will increase accordingly. Contents of the invention [0003] The object of the pre...
