Embodiment 1

[0040] Embodiment 1: Get 100 parts of PVC, 1.3 parts of organotin stabilizer, 8 parts of titanium dioxide, 8 parts of chlorinated polyethylene, 6 parts of activated calcium carbonate, 1.3 parts of ACR processing modifier, 1.2 parts of calcium stearate, oxidized polystyrene 0.2 parts of ethylene wax, 0.8 parts of Sasol wax.

[0041]The above-mentioned materials are mixed according to the following process to make a dry blend, and the process flow is as follows: figure 1 Shown:

[0042] First, the mixture was prepared by using the German Lemet automatic mixing system. The preparation process is as follows:

[0043] The main material PVC enters the PVC silo through the bag dumping station, and then is sent to the main scale by air. The auxiliary materials chlorinated polyethylene, ACR processing modifier, calcium stearate, titanium dioxide, and active calcium carbonate enter the auxiliary material scale through their respective auxiliary material tanks for weighing. scales. ...

Abstract

The invention relates to an organotin lead-free proximate matter which consists of the following matters (counted in weight portions): 100 portions of polyvinyl chloride, 1.3 to 1.5 portions of organotin stabilizing agents; 8 to 10 portions of titanium pigment, 8 to 10 portions of Haloflex, 1.3 to 1.5 portions of ACR processing modifiers; 2.0 to 29 portions of compound wax-hard calcium lubricating systems. After being counted according to a prescription, the matters are firstly processed into a mixture, and then the mixture is extruded to be the proximate matters by a double screw extruder. The proximate matter has the advantages of uniform and mild color, good impacting performance and high fillet intensity after a door and a window are assembled; besides, the output rate is high and completely accords with or exceeds the standard demands of GB / T8814-2004. The organotin stabilizing agent which is corresponding to the drinking water quality policy paper of the world health organization in particular completely abandons a lead salt stabilizing agent and thoroughly realizes free of lead.

Description

technical field [0001] The invention belongs to building enclosure materials, in particular to an organic tin lead-free plastic profile. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics in the world, and its products are widely used. Among them, the profiled materials for doors and windows have developed by leaps and bounds in recent years. Polyvinyl chloride is an amorphous high polymer. Due to the instability of its molecular structure to heat, its processing and mechanical properties are affected by heat, light and oxygen during molding, processing and storage. PVC resin and its products are due to their own structure. Defects, there are disadvantages of easy thermal degradation and aging, its processing temperature (above 160 ° C) is higher than the decomposition temperature (120-130 ° C), so PVC should be turned into products, and in order to prevent discoloration and To maintain the appearance and physical properties o...
