Embodiment 1

[0034] The new material is made of PP resin, and the production scraps are recycled LFT-D manure leakage board fragments. The diameter of the crushed particles is about 5mm. The weight ratio of the production of scraps, virgin material and glass fiber is 11:3:6. The LFT-D fecal leakage board with a length, width and height of 1500×600×35 mm and a weight of 7.85 kg was prepared.

[0035] The strength test is carried out in accordance with the corresponding national standards. The pressure in the experiment is 1300T, and the pressure holding time is tens of seconds. The obtained indicators are as follows:

[0036] Bending strength: 24.4kgf, bending strength: 106.6MPa, bending modulus: 5Gpa, beam unnotched impact strength: 40.4kJ / m 2 Compared with products processed with new materials, some indicators have improved, and all of them exceed the strength indicators of the industry standard products.

Embodiment 2

[0038] The new material is made of PP resin, and the production scraps are recycled LFT-D manure leakage board fragments. The diameter of the crushed particles is about 5mm. The weight ratio of the production of scraps, virgin material and glass fiber is 1:3:2. The prepared LFT-D fecal leakage board is 1500mm×600mm×35mm in length, width and height respectively, and its weight is 7.9kg.

[0039] The strength test is carried out in accordance with the corresponding national standards, and the indicators are as follows: Tensile strength: 47.81Mpa Bending strength: 78.37Mpa Flexural modulus: 4.88Gpa, Support beam unnotched impact strength: 40.0kJ / m 2 , All exceed the strength indicators of the industry's standard products.

Embodiment 3

[0041] The new material is made of PP resin, and the production waste is recycled LFT-D dung leakage board fragments. The diameter of the crushed particles is about 8mm. The weight ratio of the production waste, the new material and the glass fiber is 1:4:1.8. The prepared LFT-D fecal leakage board with length, width and height of 1500mm×600mm×35mm and its weight of 7.95kg was tested in accordance with the corresponding national standards. The indicators are as follows: tensile strength: 47.85Mpa, bending strength : 78.41Mpa, flexural modulus of elasticity: 4.89Gpa, unnotched impact strength of support beam: 40.4kJ / m 2 , All exceed the strength indicators of the industry's standard products.

Abstract

The invention discloses a method for preparing an LFT-D (long fiber reinforced thermoplastic composite) dung draining plate by utilizing production leftovers. The method comprises the steps of crushing the recovered LFT-D production leftovers into particles in a size of 5mm to 8mm, adding a new material according to a weight ratio of (1:3) to (1:4), adding glass fibers according to a weight ratio of the glass fibers to wastes of (1:1.8) to (1:2.1), finally uniformly mixing and heating, and extruding the mixture to a dung draining plate mold to obtain a product. Various mechanical properties of each product processed in the method can reach relevant inspection standards of the dung draining plate, and the recycling of raw materials of the LFT-D dung draining plate wastes is realized, and an important significance on environmental protection can be realized.

Description

Technical field [0001] The invention belongs to the technical field of animal husbandry, and specifically relates to a method for producing a manure leakage board for livestock breeding, in particular to a method for recycling and preparing a new manure leakage board by using waste LFT-D production scraps. Background technique [0002] At present, pigs, sheep, cattle, chickens and other livestock and poultry are generally kept in captivity. The manure leakage board is an important device in the pen. On the one hand, it can ensure that the manure and urine of the livestock can flow into the manure ditch, reduce the cost of manual cleaning, and maintain The house is clean, and at the same time, the polluted air from the indoor fly is discharged to the outside to keep the air fresh and minimize the impact of pathogens on the growth of livestock. [0003] At present, the dung leakage board is mostly made of cement or plastic. Among them, the dung leakage board made of plastic is widely...
