Abstract

The invention discloses a low-foaminess PVC section bar used for door and window frames. The low-foaminess PVC section bar comprises following ingredients, by mass, 100 parts of PVC, 2 to 6 parts of titanium dioxide, 1 to 3 parts of AC foaming agent, 0.1 to 1 part of UV-9, 2 to 5 parts of paraffin, 10 to 15 parts of CPE, 0.1 to 0.5 part of PE wax, 2 to 5 parts of tribasic lead sulfate, 2 to 4 parts of dibasic lead phosphate, 8 to 10 parts of a modifier, 5 to 10 parts of calcium carbonate, 0.5 to 1 part of calcium stearate, and 0.5 to 2.5 parts of lead stearate. Product relative density ranges from 0.75 to 0.85, tensile strength ranges from 30 to 40MPa, bending elasticity modulus range from 35 to 40MPa, bending rupturing load ranges from 14000 to 15000MPa, bending strength ranges from 35 to 45MPa, and elongation ranges from 25 to 30%. The low-foaminess PVC section bar possesses light resistance and ultraviolet irradiation resistance, and can be used for replacing existing materials continuously; and large-scaled production can be realized.

Description

technical field [0001] The application belongs to the field of plastic materials, in particular to a low-foaming PVC profile for door and window frames. Background technique [0002] PVC profiles are PVC products for industrial and domestic use that are extruded at high temperature after adding various functional additives to PVC resin; they can be divided into hard and soft according to performance. Rigid PVC profiles are mostly used in construction, such as making PVC doors and windows, PVC floors, PVC pipes, etc.; soft PVC profiles are used in PVC hoses, power transmission cables, etc. PVC profiles added with functional additives have anti-aging, anti-ultraviolet, Corrosion resistance, high strength, cheap price, good heat preservation and heat insulation performance, can partially replace aluminum profiles, steel materials, etc.; In the proposal, it is clearly pointed out that the further strengthening of infrastructure construction and the implementation of the urbaniz...
