Problems solved by technology

However, if these raw materials are directly added, there are generally problems such as insufficient life span and easy aging in the prepared leaky dung board products, which will affect the popularization and use of the products
Moreover, at present, LFT-D leaky manure board products are prone to waste or incomplete leaky manure board defective products in application, and the treatment of these products has become a technical problem in this field. So far, there is no better LFT-D composite There is an urgent need to study new recycling solutions for the recycling and reuse of material waste, and to ensure the life of the product

Embodiment 1

[0040] Embodiment 1: Raw materials are not modified and implemented

[0041] The weight ratio of Y2600PP raw material to glass fiber is 6:1, and the LFT-D leaking manure board with a size of 1500mm×600mm×35mm and a weight of 7.85kg is prepared, and the design service life is 8~10 according to the corresponding national standards. Intensity testing, the pressure in the experiment is 1300T, the holding time is tens of seconds, the obtained index is 53.5Mpa in tensile strength, 21.3Mpa in impact strength, 3.1% in elongation at break, and 40.4% in unnotched impact strength of the support beam. kJ / m 2 . According to laboratory tests, the service life at room temperature is 4 to 6 years, and the aging degree will be accelerated after that, and the service life of the original design cannot be reached.

Embodiment 2

[0042] Example 2: Implementation of Raw Material Modification + Waste

[0043] The weight ratio of Y2600PP raw material, CMG9801 compatibilizer, 1010 anti-aging agent and maleic anhydride MAH grafting agent is 100:1:0.5:1, and the inorganic polymer is grafted and connected by single-screw stirring and melting , the modified melting temperature is 240°C. After modification, take Y2600PP raw material: modified plastic particles: waste particles: glass fiber (weight ratio) is 5:1:0.5:0.6, and the size is 1500mm×600mm× 35mm leaking manure board products.

[0044] In accordance with the corresponding national standards for strength testing, the indicators are the tensile strength is 58.76Mpa, the impact strength is 47.4Mpa, the elongation at break is 4.8%, and the unnotched impact strength of the support beam is 42.0kJ / m 2 , exceed the intensity index of this industry standard product, also exceed the index of embodiment one. Its laboratory test has a service life of 6 to 8 years...

Embodiment 3

[0045] Example 3: Implementation of Raw Material Modification + Waste

[0046] The weight ratio of Y2600PP raw material, CMG9801 compatibilizer, 1010 anti-aging agent and maleic anhydride MAH grafting agent is 100:2:1:1.5, and the inorganic polymer is grafted and connected by single-screw stirring and melting , the modified melting temperature is 190°C. After modification, take Y2600PP raw material: modified plastic particles: waste particles: glass fiber (weight ratio) is 5:1:0.8:0.7, and the size is 1500mm×600mm× 35mm leaking manure board products.

[0047] According to the corresponding national standard for strength testing, the indicators are 64.52Mpa for tensile strength, 56.5Mpa for impact strength, 6.2% elongation at break, and 41.2kJ / m2 for unnotched impact strength of support beams, exceeding the industry standard products The intensity index also exceeds the index of embodiment one and embodiment two. Its laboratory test has a service life of 6 to 8 years at room ...

Abstract

The invention discloses a method for preparing an LFT-D dropping board by means of PP original materials and waste materials. According to the method, through the combination of temperature control, material improvement and a special technical formula, modified PP plastic and waste material particles are added to Y2600 original material particles in proportion and stirred and fused through double screws, and then glass fiber is added to obtain the finished product. The weather resistance and adverse environment resistance of the Y2600 original materials are poor, tenacity, weather resistance, aging resistance and the like can be improved greatly by adding modified plastic, so that the defect of poor strength is overcome and aging time is prolonged, tests on various mechanical performances of each machined product can meet the relevant dropping board inspection standards, and the purposes of improving the tenacity of the LFT-D dropping board and prolonging the service life of the LFT-D dropping board are realized. Recycling is achieved, and the method has great significance for environment protection.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a dung leaking board used for livestock breeding, especially a method for producing a dung leaking board that can be produced with special raw materials, special production technology and formula. Background technique [0002] At present, pigs, sheep, cattle, chickens and other livestock and poultry are generally raised in captivity, and the dung leaking board is an important device in the pen, on the one hand, it can ensure that the feces and urine of poultry and livestock can flow into the ditch, reduce the cost of manual cleaning, and maintain Effects on poultry growth. [0003] LFT-D (Long Fiber Reinforced Thermoplastic Composites) is compared with ordinary fiber reinforced thermoplastic materials. Usually, the fiber length in ordinary fiber reinforced thermoplastic materials is less than 1 mm, while in LFT-D, the fiber The length is generally 5 to 20 mm...
