Problems solved by technology

[0002] As we all know, the calcium carbonate used in traditional polyvinyl chloride pipes is easy to deform and soften polyvinyl chloride pipes, which cannot meet the ideal product quality requirements
Therefore, the strength and toughness of the produced polyvinyl chloride pipes are relatively poor, and the production cost is relatively high, the quality is unstable, and it is difficult to meet the needs of the market, which also limits its popularization and application.

Embodiment 1

[0014] Rigid compound calcium carbonate of the present invention is formulated by the following process procedures:

[0015] One, prepare the preparation of each component and parts by weight of the described stiffened synthetic calcium carbonate

[0016] 1. Preparation of polyvinyl chloride functional regulator:

[0017] According to the ratio of polyvinyl chloride functional regulator, take 1.5% of ethylene vinyl acetate and vinyl chloride graft copolymer, and 0.05% of aluminate coupling agent, put them together in the agitator, stir at room temperature, and stir evenly Then it can be ready for use.

[0018] 2. The preparation of each component and parts by weight:

[0019] Calcium carbonate 80; polyvinyl chloride function regulator 5; stearic acid 1, spare. (The calcium carbonate is heavy calcium carbonate or light calcium carbonate)

[0020] two. The preparation of described stiffened synthetic calcium carbonate:

[0021] Mixing: mix the above prepared components by ...

Embodiment 2

[0023] This embodiment is basically the same as Embodiment 1, the difference is that:

[0024] One, prepare the preparation of each component and parts by weight of the stiffened synthetic calcium carbonate:

[0025] 1. Preparation of polyvinyl chloride functional regulator:

[0026] According to the ratio of polyvinyl chloride functional regulator, take ethylene vinyl acetate and vinyl chloride graft copolymer 2, and aluminate coupling agent 0.07, put them into the mixer together, stir at room temperature, and stir evenly Then it can be ready for use.

[0027] 2. The preparation of each component and parts by weight:

[0028] Calcium carbonate 100; polyvinyl chloride function regulator 8; stearic acid 1.5, spare. (The calcium carbonate is heavy calcium carbonate or light calcium carbonate)

Embodiment 3

[0030] This embodiment is basically the same as Embodiment 1, the difference is that:

[0031] One, prepare the preparation of each component and parts by weight of the stiffened synthetic calcium carbonate:

[0032] 1. Preparation of polyvinyl chloride functional regulator:

[0033] According to the ratio of the polyvinyl chloride functional regulator, take 2.5% of ethylene vinyl acetate and vinyl chloride graft copolymer, and 0.10% of the aluminate coupling agent, put them together in the agitator, stir at room temperature, and stir evenly Then it can be ready for use.

[0034] 2. The preparation of each component and parts by weight:

[0035] Calcium carbonate 120; polyvinyl chloride function regulator 10; stearic acid 2, spare. (The calcium carbonate is heavy calcium carbonate or light calcium carbonate)

Abstract

The invention discloses a special reinforcing composite calcium carbonate for polyvinyl chloride pipes. The reinforcing composite calcium carbonate is made of, by weight, 80-120 parts of calcium carbonate, 5-10 parts of polyvinyl chloride functional modifier and 1-2 parts of stearic acid. The preparation process of the reinforcing composite calcium carbonate is mixing. The special reinforcing composite calcium carbonate has the advantages of reasonable conception, standard process, simplicity in operation, low cost and freeness of pollution, and using the special reinforcing composite calcium carbonate for processing of polyvinyl chloride pipes can improve product performance, lower product cost and the like. The special reinforcing composite calcium carbonate is applicable to industrial batch production and can be widely used for the field of processing of the polyvinyl chloride pipes.

Description

technical field [0001] The invention relates to a kind of calcium carbonate used for plastics, in particular to a kind of rigidified calcium carbonate specially used for polyvinyl chloride pipes. Background technique [0002] As we all know, the calcium carbonate used in traditional polyvinyl chloride pipes is easy to deform and soften polyvinyl chloride pipes, which cannot meet the ideal product quality requirements. Therefore, the strength and toughness of the produced polyvinyl chloride pipes are relatively poor, and the production cost is relatively high, the quality is unstable, and it is difficult to meet the needs of the market, which also limits its popularization and application. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the above-mentioned background technology, replace the calcium carbonate used in traditional polyvinyl chloride pipes, improve the quality of polyvinyl chloride pipes, and reduce the prod...
