Problems solved by technology

The product structure of these internal lubricants is relatively simple, and the product performance is single. Some PVC products, such as foamed boards, have higher requirements for internal lubricants, such as good lubricating performance, fast dispersion, and high stability. The internal lubricant lacks auxiliary thermal stability and cannot meet the requirements of PVC resin molding processing

Embodiment 1

[0055] Prepare the internal lubricant for PVC resin molding processing of the present invention according to the following steps:

[0056] ①. Feeding and heating

[0057] Put 78.9 parts by weight of epoxy oleic acid, 20.9 parts by weight of methyl diethylene glycol, and 00.2 parts by weight of butyl titanate into the reaction kettle, and heat up to 100°C under stirring;

[0058] ②.Condensation reaction

[0059] Step ① Feeding the heated material, under the pressure of -0.09Mpa, continue to stir, slowly raise the temperature to 190°C, and keep it warm at 190°C for 5 hours to obtain a light yellow or transparent fluid liquid. Under normal pressure, cool down to a constant temperature of 100°C, and prepare slices;

[0060] ③. Slicing and packaging

[0061] Step ② The condensation reaction product is sliced ​​by a drum-type condensation crystal slicer, and packaged after passing the quality inspection.

Embodiment 2～ Embodiment 8

[0063] According to the method and steps of Example 1, according to the formula of Table 1, the internal lubricant for PVC resin molding processing of the present invention is prepared

Abstract

The invention discloses an internal lubricant for polyvinyl chloride (PVC) resin molding processing and a preparation method thereof. The internal lubricant for PVC resin molding processing is a polymer pretreatment organic auxiliary material prepared only through carbon-carbon unsaturated bond reactions. The internal lubricant for PVC resin molding processing is characterized by comprising: by weight, 50 to 95 parts of epoxy oleic acid, 4.5 to 49.5 parts of one or more aliphatic dihydric alcohols and 0.1 to 0.5 parts of butyl titanate. The preparation method comprises the following steps of 1, raw material feeding and heating, 2, a condensation reaction, and 3, slicing and packaging. The internal lubricant for PVC resin molding processing has excellent lubricating properties, good compatibility and dispersity, and certain auxiliary heat stability. Epoxy groups of the epoxy oleic acid have chemical activity and can absorb hydrogen chloride and thus PVC plastic accelerated ageing is avoided and a stabilization effect is obtained. The internal lubricant for PVC resin molding processing has good compatibility with other components of a PVC molding processing formula system and has a low production cost.

Description

technical field [0001] The invention relates to an internal lubricant for PVC resin molding and a preparation method thereof. It belongs to the pretreatment of organic ingredients with polymer materials obtained only by the reaction of carbon-carbon unsaturated bonds. Background technique [0002] my country is a big country in the production and consumption of PVC resin. In recent years, with the rapid development of the national economy, the PVC industry has achieved great development. According to statistics, in 2009, the production capacity of PVC resin in my country has reached more than 12 million tons, the actual production volume has reached 11.2 million tons, and the apparent consumption has reached 10.5 million tons, with an annual growth rate of 14.2%. The development of PVC industry, along with the continuous prosperity of our country's economy, maintains high-speed growth and has great development potential. Positive factors such as promoting energy-saving emi...
