Abstract
The invention relates to preparation of matrix particles capable of producing degradable mulching films, in particular to alloy matrix particles for preparing the degradable mulching films. The alloy matrix particles for preparing the degradable mulching films comprises the following components in percentage by weight: 0.01 to 0.03 percent of tert-butyl peroxy isopropyl benzene, 1.50 to 2.25 percent of fumaric acid, 4.50 to 5.60 percent of microcrystalline wax, 3.60 to 5.40 percent of polyethylene wax, 3.00 to 4.20 percent of MG70, 9.00 to 13.0 percent of N210 and 68 to 80 percent of corn starch. The alloy matrix particles for preparing the degradable mulching films have the advantages that: the alloy matrix particles can be restructured with PE structures to form a network bridge, so the prepared mulching films can be degraded quite uniformly; the problem of balancing the water tolerance and the hydrophilicity is solved, so the prepared mulching films can be attached to the ground surface, are difficult to blow away by wind, and have better function when used as the mulching films; and the mulching films can be blown to the thickness of 0.005mm and have small specific gravity, so the same amount of raw materials can produce more mulching films.
Description
[technical field]
The present invention relates to technical field of biological material, relate to the preparation of the master batch of producing Biodegradable mulch, specifically, is a kind of raw material of producing Biodegradable mulch.
[background technology]
Agricultural mulching is the agriculture important production means after seed, chemical fertilizer, agricultural chemicals.Mulch film has the good soil moisture conservation effect that heats, and can significantly improve the output of farm crop.But,, cause the mulch film fragment to remain in the soil in a large number along with the common plastic film of extensive use.Along with the accumulation of mulch film fragment, a large amount of residual ground film destroys Soil structure, cause soil compaction, permeability variation, soil fertility to descend, have a strong impact on growing and output of farm crop, make crop production reduction.If every mu of residual mulch film in ground surpasses 22kg, farm crop are with the underproduction 25%; If every mu of residual mulch film in ground surpasses 50kg, the soil can't be cultivated, and will cause desertification, and they constitute serious threat to the Sustainable development of agricultural.
Be normal farming of solution farm crop and the contradiction between protection environment and the arable land, market presses for degradable agricultural mulching, especially the every mu of residual reclamation area, Xinjiang of 35kg and the Northwest of China of surpassing of arable land plastic film.In areas such as the extremely strict Japan of environmental requirement, Europe, North Americas, regulatable degradative plastic film all there is urgent demand.
The manufacturing technology that photodegradation, oxidative degradation, several degradative plastic films of biological degradation are arranged at present.But, because mulch film need satisfy the different insulation of different crops, the requirement of soil moisture conservation phase in the totally different weather in various places, edatope, and can degrade on time, can not shift to an earlier date, can not postpone.So degradative plastic film must be according to the requirement design degraded life-span of various places weather, edatope and different crops insulation soil moisture conservation phase, this has the technical requirements of high accuracy controlling degradation cycle to mulch film manufacturers.Because technical difficulty is big, production cost is higher, rarely has the degradative plastic film product of success so far on the market.
The master batch of existing Biodegradable mulch also comes with some shortcomings owing to technical problem, for example: 1. can not with polyethylene (PE) structural rearrangement, it is a kind of form of parcel, can not form the structure that network is built bridge, cause the degraded of degradable mulch inhomogeneous, it is not thorough to degrade, and residual particles or fragment easily cause secondary pollution; 2. can not solve water tolerance and hydrophilic equilibrium problem, it shows as, and the mulch film of making can not be close to the face of land, is blown away functional relatively poor relatively as mulch film easily by wind; 3. raw material particle size is had high requirement, the film that blows out is thicker, and feed consumption is many, and cost is higher.
[summary of the invention]
The object of the present invention is to provide a kind of master batch of producing Biodegradable mulch, thinner with its film that blows out, subsides ground property is better, and can degrade fully.
For realizing above purpose, the technical scheme that the present invention takes is:
A kind of alloy master batch for preparing degradative plastic film, the weight percent of its component is:
Tert-butyl peroxy isopropyl benzene (BIPB): 0.01～0.03%;
Fumaric acid (FUMARIC ACID TECH GRADE): 1.50～2.25%;
Microcrystalline Wax: 4.50～5.60%;
Polyethylene wax: 3.60～5.40%;
MG70(LDPE)：3.00～4.20％；
N210：9.00～13.0％；
W-Gum: 68～80%.
Described W-Gum is 98 purpose industrial starch.
The positively effect that the present invention prepares the alloy master batch of degradative plastic film is:
(1) can with the PE structural rearrangement, form network and build bridge, make the ground membrane degradation of making very thorough, and evenly;
(2) solved water tolerance and hydrophilic equilibrium problem, made the mulch film of making to be attached to the face of land, be difficult for being blown away, be used as the functional better of mulch film by wind;
(3) mulch film can be blown to the thickness of 0.005mm, proportion is little, and equal raw material can be made more mulch film.
(4) can use 98 order industrial starch and PE network to build bridge, greatly reduce the manufacturing cost of product.
[description of drawings]
Accompanying drawing is the degradation effect detection curve figure of the mulch film made of alloy master batch of the present invention.
[embodiment]
Prepare in the concrete enforcement of alloy master batch of degradative plastic film in the present invention, can take the production of preparing burden of the existing granulation technique of said components utilization, the source of its raw material can be:
Tert-butyl peroxy isopropyl benzene (BIPB) can adopt Shanghai Fang Rui to reach the product of chemical company limited;
Fumaric acid (FUMARIC ACID TECH GRADE) adopts the product of Changzhou biochemical engineering limited-liability company;
The product that Microcrystalline Wax can adopt Jingmen, Hubei to produce;
