Embodiment 1

[0040] A PC and PVC composite board and its production process;

[0041] The technical problem to be solved by the present invention adopts the following technical solutions to realize:

[0042] A PC and PVC composite board and its production process, comprising the following steps:

[0043] (1) Butadiene rubber and nano-modified alkyd resin are added in the mixed acid solution of 80 times of its weight, and the mixed acid is composed of 60% carbonic acid and 87% hydrochloric acid solution with a mass ratio of 3:1, Sonicate at 55°C for 17 minutes, filter, wash the precipitate twice with water, and dry in vacuum at 70°C for 30 minutes to obtain acidified modified butylpyridine rubber;

[0044] (2) Get 47% of the weight of the above-mentioned acidified modified butylpyridine rubber, mix it with easy-to-mix tank black, foam regulator DLF, vaseline, light calcium carbonate, antimony trioxide, zinc carbonate, and add to the mixture weight 70 In N-cyclohexyl-2-benzothiazole sulfen...

Embodiment 2

[0058] A PC and PVC composite board and its production process;

[0059] The technical problem to be solved by the present invention adopts the following technical solutions to realize:

[0060] The prepared PC and PVC composite board Chen Hua method comprises the following steps:

[0061] Fix the newly produced PC and PVC composite boards. When arranging the boards, the partitions should be kept flush with both ends of the PC and PVC composite boards, and the upper and lower partitions should be kept vertical to prevent excessive moisture at the ends of the PC and PVC composite boards. Dissipation, uneven shrinkage leads to end cracks, and the upper and lower partitions are kept vertical to prevent the PC and PVC composite boards from bearing gravity balance or not to prevent warping; and each PC and PVC composite boards are arranged alternately, and each PC and PVC composite board at the same level Leave 0.8cm between the composite boards; for PC and PVC composite boards of...

Abstract

The invention discloses a PC-PVC composite plate and a production process thereof. The PC-PVC composite plate comprises the following parts: in parts, 10-13 parts of easily mixed channel black, 0.5-3parts of a foaming regulator DLF, 20-25 parts of PVCS-700 resin, 22-28 parts of polycarbonate, 5-12 parts of vaseline, 10-15 parts of light calcium carbonate, 7-13 parts of antimony trioxide, 11-14 parts of zinc carbonate, 6-15 parts of stearic acid, 6-15 parts of salicylic acid, 20-35 parts of pottery clay, 10-20 parts of graphite, 5-10 parts of aloe vera gel, 15-27 parts of diatom mud, 14-29 parts of activated carbon, 6-15 parts of nano modified alkyd resin, 2.5-5 parts of an impact modifier ACM, 0.5-4 parts of polyethylene wax, 0.5-1 part of stearic acid, 0.5-5 parts of an anti-aging agent,77-94 parts of pyridine butadiene rubber, 37-48 parts of Camphora officinarum powder, 4-12 parts of an accelerator TMTM, 1-3 parts of N-cyclohexyl-2-benzothiazole sulfenamide and 16-19 parts of N-phenyl-1-naphthylamine. The PC-PVC composite plate has efficient impact resistance, environmental protection, high heat resistance, toughness, fatigue resistance, self lubrication, low friction coefficient, weather resistance, resistance to corrosion of hot water, alkali, acid, oil and halogenated hydrocarbons and strong hydrolysis resistance, and has a high practical value.

Description

Technical field: [0001] The invention relates to the related technical field of composite boards, in particular to a PC and PVC composite board and a production process thereof. Background technique: [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. [0003] The natural color of polyvinyl chloride (PVC) is light yellow translucent and shiny. Transparency is better than polyethylene and polypropylene, and worse than polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. Soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. And...
