Abstract
The invention provides a PVC environmental-protection nontoxic toughening agent comprising, by mass ratio, 10-70% of vegetable fatty acid and 30-90% of pentaerythritol. The toughening agent is high in plasticizing efficiency, low-temperature impact resistance, and tearing strength, relatively low in mobility, and good in lubricity, and is nontoxic and of environmental protection.
Description
Technical field
The present invention relates to a kind of PVC environment-protecting asepsis toughening agent.
Background technology
China is a big country having 1,300,000,000 populations, plastic cement and plasthetics thereof and daily life closely bound up.Except being applied to the product for civilian use, be also applied to industry and national defence, its product space is not second to iron and steel, and range of application is other material and irreplaceable.As everyone knows, the moulding process of plasthetics is completed by operations such as coordinating, plasticate, be shaping substantially.In this process, resin, auxiliary agent, processing units
(comprising mould) is indispensable fundamental.By contrast, the consumption of auxiliary agent in plastic formula is less, and general proportion is less than 8%, but its effect is very important, is to improve the goods processing of product and the principal element of application performance.Can say, after fluoropolymer resin structure is determined, the choice and application of auxiliary agent is the key determining goods success or failure.
Plastic cement auxiliary agent class is numerous and jumbled, Various Functions.Different according to function and efficacy, generally include stabilizing additive, process systems auxiliary agent and function endowing agent three major controls.With plastic cement industrial development, the increase of plastic resin structure, the raising that the progress of forming processing technology and Application Areas require product properties, greatly facilitates the expansion of plastic cement auxiliary agent class and produces the raising of consumption.
Additives for plastics has good development prospect in China, the particularly fast development of the high-tech area such as building, automobile, agricultural, packaging and electronics, space flight and aviation, information technology, can be more urgent to the demand of functionalization, customizations, nontoxic, oligosaprobic plastics and spare and accessory parts, Plastics Additives in expansion scale, increase production capacity, improve quality, increase the benefit while, the new variety of progressively central transference is nontoxic to independent research and development, efficient, multi-functional, customizations and high added value are come, and realizes industrialization as early as possible.
There is a lot of problems in current plastic cement industry softening agent used in PVC, the main raw material of common softening agent is two sad, and its composition has very large toxic side effect to human body.In other side, be embodied in that plasticizing efficiency is low, low temperature time unstable properties, volatility is high, transport property is larger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of PVC environment-protecting asepsis toughening agent, and plasticizing efficiency is high, low-temperature impact resistance and tearing toughness ability is high, volatility is low, transport property is less, oilness is good, asepsis environment-protecting.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of PVC environment-protecting asepsis toughening agent, be that the vegetable fatty acid of 10% ~ 70% and the tetramethylolmethane of 30% ~ 90% form by mass ratio, be made through 185 DEG C of high temperature particular polymeric techniques, described vegetable fatty acid is soybean oil or plam oil.
As preferably, the mass ratio of described vegetable fatty acid is 10%, and the mass ratio of tetramethylolmethane is 90%.
As preferably, the mass ratio of described vegetable fatty acid is 70%, and the mass ratio of tetramethylolmethane is 30%.
As preferably, the mass ratio of described vegetable fatty acid is 40%, and the mass ratio of tetramethylolmethane is 60%.
Beneficial effect: the present invention is owing to being that the vegetable fatty acid of 10% ~ 70% and the tetramethylolmethane of 30% ~ 90% form by weight ratio, plasticizing efficiency is high, low-temperature impact resistance and tearing toughness ability is high, volatility is low, transport property is less, oilness is good, asepsis environment-protecting.
Embodiment
Embodiment one:
The mass ratio of vegetable fatty acid is 10%, and the mass ratio of tetramethylolmethane is 90%, is made through 185 DEG C of high temperature particular polymeric techniques.
The key technical indexes:
Outward appearance: micro-tool fatty taste, yellow or pale yellow oily liquid body
Viscosity: 10 ~ 25mpa.s (80 DEG C)
Zero pour :-15C °
Flash-point: >=200 DEG C
Moisture :≤0.5%
Embodiment two:
The mass ratio of vegetable fatty acid is 70%, and the mass ratio of tetramethylolmethane is 30%, is made through 185 DEG C of high temperature particular polymeric techniques.
Embodiment three:
The mass ratio of vegetable fatty acid is 40%, and the mass ratio of tetramethylolmethane is 60%, is made through 185 DEG C of high temperature particular polymeric techniques.
A kind of PVC environment-protecting asepsis toughening agent of the present invention, plasticizing efficiency is high, low-temperature impact resistance and tearing toughness ability is high, volatility is low, transport property is less, oilness is good, asepsis environment-protecting.The product manufacturing of winter hardiness agricultural film, Frozen Food Packaging film, electric wire, cable, outdoor water pipe etc. can be widely used in, there is good economic benefit and social benefit.
